The driver now uses the default voltage settings found in the devicetree,

2. The regulator name used to power on or power off the phy was put in the devicetree
variable "phy_regulator", which is not standard and added a lot of code for nothing.
The driver now uses the devicetree property "phy-supply" and the corresponding functions
to manipulate this regulator.
The corresponding devicetree files are also updated. As this new binding for
rk3288 has not been released with any official kernel yet (not until 3.20),

Interhost aggregate 24 Gb/s 24 Gb/s
Intrahost single stream 14 Gb/s 14 Gb/s

However, this can increase the number of grant ops per packet which

net: bridge: reject DSA-enabled master netdevices as bridge members
DSA-enabled master network devices with a switch tagging protocol should
strip the protocol specific format before handing the frame over to
higher layer.
When adding such a DSA master network device as a bridge member, we go
through the following code path when receiving a frame:
__netif_receive_skb_core
-> first ptype check against ptype_all is not returning any
handler for this skb
-> check and invoke rx_handler:
-> deliver frame to the bridge layer: br_handle_frame
DSA registers a ptype handler with the fake ETH_XDSA ethertype, which is
called *after* the bridge-layer rx_handler has run. br_handle_frame()
tries to parse the frame it received from the DSA master network device,
and will not be able to match any of its conditions and jumps straight
at the end of the end of br_handle_frame() and returns
RX_HANDLER_CONSUMED there.
Since we returned RX_HANDLER_CONSUMED, __netif_receive_skb_core() stops
RX processing for this frame and returns NET_RX_SUCCESS, so we never get
a chance to call our switch tag packet processing logic and deliver
frames to the DSA slave network devices, and so we do not get any
functional bridge members at all.
Instead of cluttering the bridge receive path with DSA-specific checks,
and rely on assumptions about how __netif_receive_skb_core() is
processing frames, we simply deny adding the DSA master network device
(conduit interface) as a bridge member, leaving only the slave DSA
network devices to be bridge members, since those will work correctly in
all circumstances.

The logic to configure a network interface for kernel IP
auto-configuration is very simplistic, and does not handle the case
where a device is stacked onto another such as with DSA. This causes the
kernel not to open and configure the master network device in a DSA
switch tree, and therefore slave network devices using this master
network devices as conduit device cannot be open.
This restriction comes from a check in net/dsa/slave.c, which is
basically checking the master netdev flags for IFF_UP and returns
-ENETDOWN if it is not the case.
Automatically bringing-up DSA master network devices allows DSA slave
network devices to be used as valid interfaces for e.g: NFS root booting
by allowing kernel IP autoconfiguration to succeed on these interfaces.
On the reverse path, make sure we do not attempt to close a DSA-enabled
device as this would implicitely prevent the slave DSA network device
from operating.

- Removed big endian support for initial version (will add it later)
v6->v7
- Fixed some minor documentation error and also modified the netcp driver
to fix the set* functions to include correct le/be macros.

v4->v5
- Sorry to spin v5 quickly but I missed few check-patch warnings which
were pointed by Joe Perches(thanks). I folded his changes [5] along with
few more check-patch warning fixes. I would like get this in for v3.18
merge window if David is happy with this version.
v3->v4
- Couple of fixes in in error path as pointed [4] out by David. Rest of

The network coprocessor (NetCP) is a hardware accelerator that processes
Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet
switch sub-module to send and receive packets. NetCP also includes a packet
accelerator (PA) module to perform packet classification operations such as
header matching, and packet modification operations such as checksum
generation. NetCP can also optionally include a Security Accelerator(SA)
capable of performing IPSec operations on ingress/egress packets.
Keystone SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which

====================
netns: allow to identify peer netns
The goal of this serie is to be able to multicast netlink messages with an
attribute that identify a peer netns.
This is needed by the userland to interpret some information contained in
netlink messages (like IFLA_LINK value, but also some other attributes in case
of x-netns netdevice (see also
http://thread.gmane.org/gmane.linux.network/315933/focus=316064 and
http://thread.gmane.org/gmane.linux.kernel.containers/28301/focus=4239)).
Ids of peer netns can be set by userland via a new rtnl cmd RTM_NEWNSID. When
the kernel needs an id for a peer (for example when advertising a new x-netns
interface via netlink), if the user didn't allocate an id, one will be
automatically allocated.
These ids are stored per netns and are local (ie only valid in the netns where
they are set). To avoid allocating an int for each peer netns, I use
idr_for_each() to retrieve the id of a peer netns. Note that it will be possible
to add a table (struct net -> id) later to optimize this lookup if needed.
Patch 1/4 introduces the rtnetlink API mechanism to set and get these ids.
Patch 2/4 and 3/4 implements an example of how to use these ids when advertising
information about a x-netns interface.
And patch 4/4 shows that the netlink messages can be symetric between a GET and
a SET.
iproute2 patches are available, I can send them on demand.
Here is a small screenshot to show how it can be used by userland.

netlink: make nlmsg_end() and genlmsg_end() void
Contrary to common expectations for an "int" return, these functions
return only a positive value -- if used correctly they cannot even
return 0 because the message header will necessarily be in the skb.
This makes the very common pattern of
if (genlmsg_end(...) < 0) { ... }
be a whole bunch of dead code. Many places also simply do
return nlmsg_end(...);
and the caller is expected to deal with it.
This also commonly (at least for me) causes errors, because it is very
common to write
if (my_function(...))
/* error condition */
and if my_function() does "return nlmsg_end()" this is of course wrong.
Additionally, there's not a single place in the kernel that actually
needs the message length returned, and if anyone needs it later then
it'll be very easy to just use skb->len there.
Remove this, and make the functions void. This removes a bunch of dead
code as described above. The patch adds lines because I did
I could have preserved all the function's return values by returning
skb->len, but instead I've audited all the places calling the affected
functions and found that none cared. A few places actually compared
the return value with <= 0 in dump functionality, but that could just
be changed to < 0 with no change in behaviour, so I opted for the more
efficient version.
One instance of the error I've made numerous times now is also present
in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't
check for <0 or <=0 and thus broke out of the loop every single time.
I've preserved this since it will (I think) have caused the messages to
userspace to be formatted differently with just a single message for
every SKB returned to userspace. It's possible that this isn't needed
for the tools that actually use this, but I don't even know what they
are so couldn't test that changing this behaviour would be acceptable.

bridge: fix setlink/dellink notifications
problems with bridge getlink/setlink notifications today:
- bridge setlink generates two notifications to userspace
- one from the bridge driver
- one from rtnetlink.c (rtnl_bridge_notify)
- dellink generates one notification from rtnetlink.c. Which
means bridge setlink and dellink notifications are not
consistent
- Looking at the code it appears,
If both BRIDGE_FLAGS_MASTER and BRIDGE_FLAGS_SELF were set,
the size calculation in rtnl_bridge_notify can be wrong.
Example: if you set both BRIDGE_FLAGS_MASTER and BRIDGE_FLAGS_SELF
in a setlink request to rocker dev, rtnl_bridge_notify will
allocate skb for one set of bridge attributes, but,
both the bridge driver and rocker dev will try to add
attributes resulting in twice the number of attributes
being added to the skb. (rocker dev calls ndo_dflt_bridge_getlink)
There are multiple options:
1) Generate one notification including all attributes from master and self:
But, I don't think it will work, because both master and self may use
the same attributes/policy. Cannot pack the same set of attributes in a
single notification from both master and slave (duplicate attributes).
2) Generate one notification from master and the other notification from
self (This seems to be ideal):
For master: the master driver will send notification (bridge in this
example)
For self: the self driver will send notification (rocker in the above
example. It can use helpers from rtnetlink.c to do so. Like the
ndo_dflt_bridge_getlink api).
This patch implements 2) (leaving the 'rtnl_bridge_notify' around to be used
with 'self').
v1->v2 :
- rtnl_bridge_notify is now called only for self,
so, remove 'BRIDGE_FLAGS_SELF' check and cleanup a few things
- rtnl_bridge_dellink used to always send a RTM_NEWLINK msg
earlier. So, I have changed the notification from br_dellink to
go as RTM_NEWLINK

Intel Wired LAN Driver Updates 2015-01-16
This series contains updates to i40e and i40evf.
This series is a little bit larger than normal because two of the patches are
version bumps.
Shannon provides tweaks to i40e and i40evf to keep the firmware, software
and silicon validation in line together by removing unused and
deprecated code, adding define for iSCSI and fix queue mask size. Fix
i40e so we do not give up in the reset/rebuild process if DCB setup
fails, just handle it the same as in the probe setup. Cleans up PTP
log messages by removing the use of __func__ as we are not using that
any longer and removes the netdev name, since that can change and can
be misleading. Adds struct size checks to indirect and command
structs that were left out previously. Added admin queue API updates
(LLDP control, OEM OCSD and OCBB commands).
Kevin increases ASQ timeout for scenarios with multi-function devices.
Carolyn fixes a problem where the interrupts descriptions from the MSIx
configuration were truncating the needed bus info, which makes it hard
to distinguish configurations from port to port. Increased the string
buffer size in order to allow the full data to be displayed.
Sravanthi cleans up the dump stats string from debugfs.
Jacob updates i40e to only enable the PTP interrupt in PFs which have PTP
enabled, instead of blindly enabling the PTP interrupt flags for all PFs.
Also updated i40e so that we do not do Tx or Rx timestamps if we do not
have PTP enabled. Added the same check against pf->ptp_rx as we have
in Rx timestamp code path because it is possible that the user can
configure only Tx hardware timestamping so we do not want to check for
Rx timestamp hang since the software won't be handling them.
Neerav updates the driver to disable firmware LLDP agent for NICs with
a firmware version lower than v4.3 and added a message when this happens.
Adds parsing and reporting of iSCSI capability for a given device or
function, as well as adding support for iSCSI partition type with DCB
in NPAR mode.

amd-xgbe-phy: Allow certain PHY settings to be set by UEFI
Certain PHY settings need to be configurable by UEFI depending on the
platform being used. Add new device tree / ACPI properties that, if
present, will override the pre-determined values currently used.

amd-xgbe-phy: Change auto-negotiation logic
The auto negotiation logic was geared to being the initiator of the
auto negotiation. This presented problems when auto negotiation was
initiated by the remote end. Change the auto negotiation logic to
make use of the auto negotiation event interrupt thus allowing the
auto negotiation state machine to function properly in either scenario.
This also removes the polling during auto-negotiation.

amd-xgbe: Remove need for Tx path spinlock
Since the Tx ring cleanup can run at the same time that data is being
transmitted, a spin lock was used to protect the ring. This patch
eliminates the need for Tx spinlocks by updating the current ring
position only after all ownership bits for data being transmitted have
been set. This will insure that ring operations in the Tx cleanup path
do not interfere with the ring operations in the Tx transmit path.

amd-xgbe: Clear all state during a device restart
When performing a device restart, like during an MTU change, sometimes
the device queues still have data and get hung up trying to flush
resulting in the device becoming unresponsive until brought down and
back up. To prevent this, always perform a device reset during a
restart.

i40e: Support for NPAR iSCSI partition with DCB
Add parsing and reporting of iSCSI capability for a given device or
function.
Also add support for iSCSI partition type with DCB in NPAR mode.
In this mode it is expected that software would configure both the LAN
and iSCSI traffic classes for the iSCSI partition; whereas all the NIC
type partitions will use LAN TC (TC0) only.
Hence, the patch enables querying of DCB configuration in MFP mode and
configures TCs for iSCSI partition type.
Though NIC type partitions may not have more than 1 TC enabled for them
the port may have multiple TCs enabled and hence I40E_FLAG_DCB_ENABLED
will be set/reset on all the partitions based on number of TCs on the
port. This is required as in DCB environment it is expected that all
traffic will be priority tagged.

i40e: when Rx timestamps disabled set specific mode
Instead of leaving the Rx timestamps in the same mode as before if we
disable the Rx logic, we can set it into a mode that has the fewest
possible timestamps generated. To do this, select only V1 mode, but do
not enable UDP packet recognition. This should eliminate all (or at
least almost all) Rx timestamps, since V1 packets are always over UDP.

i40e: use same check for Rx hang as for Rx timestamps
It's possible that the user configured only Tx hardware timestamping,
and thus we might be receiving PTP traffic which we timestamp but which
software never reads. In this case we don't want to check for Rx
timestamp hang, because we already know that software won't be handling
them. Thus, we add the same check against pf->ptp_rx as we have in the
Rx timestamp code path.
