net: ethernet: ti: cpsw: use for mcast entries only host port
In dual-emac mode the cpsw driver sends directed packets, that means
that packets go to the directed port, but an ALE lookup is performed
to determine untagged egress only. It means that on tx side no need
to add port bit for ALE mcast entry mask, and basically ALE entry
for port identification is needed only on rx side.
So, add only host port in dual_emac mode as used directed
transmission, and no need in one more port. For single port boards
and switch mode all ports used, as usual, so no changes for them.
Also it simplifies farther changes.
In other words, mcast entries for dual-emac should behave exactly
like unicast. It also can help avoid leaking packets between ports
with same vlan on h/w level if ports could became members of same vid.
So now, for instance, if mcast address 33:33:00:00:00:01 is added then
entries in ALE table:
vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x1
vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x1
Instead of:
vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x3
vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x5

it's done in cpsw_ale_set_allmulti().

This series implements the missing accounting as well as support for

Note that counters are maintained on per-queue basis for XDP but not
otherwise (per-cpu and atomic as before). This is because 1) tx path in
veth is essentially lockless so we cannot update per-queue stats on tx,
and 2) rx path is net core routine (process_backlog) which cannot update
per-queue based stats when XDP is disabled. On the other hand there are
real rxqs and napi handlers for veth XDP, so update per-queue stats on
rx for XDP packets, and use them to calculate tx counters as well,

however I think the value of staying within 80 columns is higher than the
value of having the string on a single line. This is because with all the
formatting specifiers there it is not directly greppable based on the
final output produced to the kernel log on one hand, e.g.:
tc2: ROM rev. 1.0, firmware rev. 1.2, RMC rev. A, SMT ver. 1
while it can be easily tracked down by grepping for an obvious substring
such as "RMC rev" on the other.
The issue with MMIO barriers I discussed in the course of the original
review turned out mostly irrelevant to this driver, because as I have
learnt in a recent Alpha/Linux discussion starting here:
<https://marc.info/?i=alpine.LRH.2.02.1808161556450.13597%20()%20file01%20!%20intranet%20!%20prod%20!%20int%20!%20rdu2%20!%20redhat%20!%20com>
our MMIO API mandates the `readX' and `writeX' accessors to be strongly
ordered with respect to each other, even if that is not implicitly
enforced by hardware.
Consequently I have removed all the explicit ordering barriers and
instead submitted a fix for MIPS MMIO implementation, which currently does
not guarantee strong ordering (the MIPS architecture does not define bus
ordering rules except in terms of SYNC barriers), as recorded here:
<https://patchwork.linux-mips.org/project/linux-mips/list/?series=1538>.
Enforcing strong MMIO ordering can be costly however and is often
unnecessary, e.g. when using PIO to access network frame data in onboard
packet memory. I have therefore retained the information that would be
lost by the removal of barriers, by defining accessor wrappers suffixed by
`_o' and `_u', for accesses that have to be ordered and can be unordered
respectively.
If we ever have an API defined for weakly-ordered MMIO accesses, then
these wrappers can be redefined accordingly. Right now they all expand to
the respective `_relaxed' accessors, because, again, enforcing the
ordering WRT DMA transfers can be costly and we don't need it here except
in one place, where I chose to use explicit `dma_rmb' instead.
Similarly I have replaced the completion barriers with a read back from
the respective MMIO location (all adapter MMIO registers can be read with
no side effects incurred), which will serve its purpose on the basis of
MMIO being strongly ordered (although a read from TURBOchannel is going to
be slower than `iob', making the delay incurred unnecessarily longer).
And last but not least, I have split off the SMT Tx network tap support
to a separate change, 2/2 in this series, so that it does not block the
driver proper and can be discussed separately.
I think it has value in that it makes the view of the outgoing network
traffic complete, as if one actually physically tapped into the outgoing
line of the ring, between the station being examined and its downstream
neighbour. Without this part only traffic passed from applications
through the whole protocol stack can be captured and this is only a part
of the view.
With the `dev_queue_xmit_nit' interface now exported it's only
`ptype_all' that remains private, and to define a properly abstracted API
I propose to provide am exported `dev_nit_active' predicate that tells
whether any taps are active. This predicate is then used accordingly.
NB if there is a long-term maintenance concern about the `dev_nit_active'
predicate, then well, corresponding inline code currently present in
`xmit_one' has to be maintained anyway, and if the resulting changes
require `defza' to be updated accordingly, then I am going to handle it;
after some 20 years with Linux it's not that I am going to disappear
anywhere anytime. And once I am dead, which is inevitably going to happen
sooner or later, then the driver can simply be ripped from the kernel.
Though I suspect that at that point no DECstation Linux users may survive
anymore, even though hardware, being as sturdy as it is, likely will.
I have a patch for `tcpdump' to actually decode SMT frames, which I plan
to upstream sometime. Here's a sample of SMT traffic captured through the
`defza' driver in a small network of 4 stations and no concentrators,
printed in the most verbose mode:
FDDI: defza: Support capturing outgoing SMT traffic
DEC FDDIcontroller 700 (DEFZA) uses a Tx/Rx queue pair to communicate
SMT frames with adapter's firmware. Any SMT frame received from the RMC
via the Rx queue is queued back by the driver to the SMT Rx queue for
the firmware to process. Similarly the firmware uses the SMT Tx queue
to supply the driver with SMT frames which are queued back to the Tx
queue for the RMC to send to the ring.
When a network tap is attached to an FDDI interface handled by `defza'
any incoming SMT frames captured are queued to our usual processing of
network data received, which in turn delivers them to any listening
taps.
However the outgoing SMT frames produced by the firmware bypass our
network protocol stack and are therefore not delivered to taps. This in
turn means that taps are missing a part of network traffic sent by the
adapter, which may make it more difficult to track down network problems
or do general traffic analysis.
Call `dev_queue_xmit_nit' then in the SMT Tx path, having checked that
a network tap is attached, with a newly-created `dev_nit_active' helper
wrapping the usual condition used in the transmit path.

FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapter
Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment
Corporation's first-generation FDDI network interface adapter, made for
TURBOchannel and based on a discrete version of what eventually became
Motorola's widely used CAMEL chipset.
The CAMEL chipset is present for example in the DEC FDDIcontroller
TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support
with the `defxx' driver, however the host bus interface logic and the
firmware API are different in the DEFZA and hence a separate driver is
required.
There isn't much to say about the driver except that it works, but there
is one peculiarity to mention. The adapter implements two Tx/Rx queue
pairs.
Of these one pair is the usual network Tx/Rx queue pair, in this case
used by the adapter to exchange frames with the ring, via the RMC (Ring
Memory Controller) chip. The Tx queue is handled directly by the RMC
chip and resides in onboard packet memory. The Rx queue is maintained
via DMA in host memory by adapter's firmware copying received data
stored by the RMC in onboard packet memory.
The other pair is used to communicate SMT frames with adapter's
firmware. Any SMT frame received from the RMC via the Rx queue must be
queued back by the driver to the SMT Rx queue for the firmware to
process. Similarly the firmware uses the SMT Tx queue to supply the
driver with SMT frames that must be queued back to the Tx queue for the
RMC to send to the ring.
This solution was chosen because the designers ran out of PCB space and
could not squeeze in more logic onto the board that would be required to
handle this SMT frame traffic without the need to involve the driver, as
with the later DEFTA/DEFEA/DEFPA adapters.
Finally the driver does some Frame Control byte decoding, so to avoid
magic numbers some macros are added to <linux/if_fddi.h>.

the mac register. At this time, during the driver
init the wmi has already been detached. This can
cause unexpected behavior since the firmware is
already down and the wmi has been detached.
Send the wmi command for setting probe request
oui during the driver start. This will make sure
that the firmware is started and wmi is initialized
before we send this command.

ath10k: fix possible out of bound access of ath10k_rates array
While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
from the passed bitrate, there is a chance of out of bound array access
when wrong bitrate is passed. This is fixed by comparing the bitrates
within the correct size of the ath10k_rates array.
Fixes commit f279294e9ee2 ("ath10k: add support for configuring management
packet rate"). Also correction made to some indents used in the above commit.

Beacons are not updated to reflect TIM changes. This is not compliant with
power-saving client stations as the beacons do not have valid TIM and can
cause the network to stall at random occasions and to have highly variable
latencies.
Fix it by updating beacon templates on mac80211 set_tim callback.
