tcp: avoid resetting ACK timer in DCTCP
The recent fix of acking immediately in DCTCP on CE status change
has an undesirable side-effect: it also resets TCP ack timer and
disables pingpong mode (interactive session). But the CE status
change has nothing to do with them. This patch addresses that by
using the new one-time immediate ACK flag instead of calling
tcp_enter_quickack_mode().

net: ipv6_gre: Fix GRO to work on IPv6 over GRE tap
IPv6 GRO over GRE tap is not working while GRO is not set
over the native interface.
gro_list_prepare function updates the same_flow variable
of existing sessions to 1 if their mac headers match the one
of the incoming packet.
same_flow is used to filter out non-matching sessions and keep
potential ones for aggregation.
The number of bytes to compare should be the number of bytes
in the mac headers. In gro_list_prepare this number is set to
be skb->dev->hard_header_len. For GRE interfaces this hard_header_len
should be as it is set in the initialization process (when GRE is
created), it should not be overridden. But currently it is being overridden
by the value that is actually supposed to represent the needed_headroom.
Therefore, the number of bytes compared in order to decide whether the
the mac headers are the same is greater than the length of the headers.
As it's documented in netdevice.h, hard_header_len is the maximum
hardware header length, and needed_headroom is the extra headroom
the hardware may need.
hard_header_len is basically all the bytes received by the physical
till layer 3 header of the packet received by the interface.
For example, if the interface is a GRE tap then the needed_headroom
should be the total length of the following headers:
IP header of the physical, GRE header, mac header of GRE.
It is often used to calculate the MTU of the created interface.
This patch removes the override of the hard_header_len, and
assigns the calculated value to needed_headroom.
This way, the comparison in gro_list_prepare is really of
the mac headers, and if the packets have the same mac headers
the same_flow will be set to 1.

The functionality added by this series is still reduced but its only a

====================
More complete PHYLINK support for mv88e6xxx
Previous patches added sufficient PHYLINK support to the mv88e6xxx
that it did not break existing use cases, basically fixed-link phys.
This patchset builds out the support so that SFP modules, up to
2.5Gbps can be supported, on mv88e6390X, on ports 9 and 10. It also
provides a framework which can be extended to support SFPs on ports
2-8 of mv88e6390X, 10Gbps PHYs, and SFP support on the 6352 family.
Russell King did much of the initial work, implementing the validate
and mac_link_state calls. However, there is an important TODO in the
commit message:
needs to call phylink_mac_change() when the port link comes up/goes down.
The remaining patches implement this, by adding more support for the
SERDES interfaces, in particular, interrupt support so we get notified
when the SERDES gains/looses sync.
This has been tested on the ZII devel C, using a Clearfog as peer
device.

rxrpc: Fix the keepalive generator [ver #2]
AF_RXRPC has a keepalive message generator that generates a message for a
peer ~20s after the last transmission to that peer to keep firewall ports
open. The implementation is incorrect in the following ways:
(1) It mixes up ktime_t and time64_t types.
(2) It uses ktime_get_real(), the output of which may jump forward or
backward due to adjustments to the time of day.
(3) If the current time jumps forward too much or jumps backwards, the
generator function will crank the base of the time ring round one slot
at a time (ie. a 1s period) until it catches up, spewing out VERSION
packets as it goes.
Fix the problem by:
(1) Only using time64_t. There's no need for sub-second resolution.
(2) Use ktime_get_seconds() rather than ktime_get_real() so that time
isn't perceived to go backwards.
(3) Simplifying rxrpc_peer_keepalive_worker() by splitting it into two
parts:
(a) The "worker" function that manages the buckets and the timer.
(b) The "dispatch" function that takes the pending peers and
potentially transmits a keepalive packet before putting them back
in the ring into the slot appropriate to the revised last-Tx time.
(4) Taking everything that's pending out of the ring and splicing it into
a temporary collector list for processing.
In the case that there's been a significant jump forward, the ring
gets entirely emptied and then the time base can be warped forward
before the peers are processed.
The warping can't happen if the ring isn't empty because the slot a
peer is in is keepalive-time dependent, relative to the base time.
(5) Limit the number of iterations of the bucket array when scanning it.
(6) Set the timer to skip any empty slots as there's no point waking up if
there's nothing to do yet.
This can be triggered by an incoming call from a server after a reboot with
AF_RXRPC and AFS built into the kernel causing a peer record to be set up
before userspace is started. The system clock is then adjusted by
userspace, thereby potentially causing the keepalive generator to have a
meltdown - which leads to a message like:
