This patch fixes a bug for ethtool's get_link_ksettings().
When phy exists, we should get autoneg from phy rather than from mac.
Because the value of mac.autoneg is invalid when phy exists.

Recent IRQ coalescing clean up has removed a guard-rail for the max DMA
buffer coalescing value. This is a 6-bit value and must not be 0. We
already have a check for 0 but 64 is equivalent to 0 and will cause
non-stop interrupts. Fix it by adding the proper check.

When we do tunnel or beet mode, we pass saddr and daddr from the
template to xfrm_state_find(), this is ok. On transport mode,
we pass the addresses from the flowi, assuming that the IP
addresses (and address family) don't change during transformation.
This assumption is wrong in the IPv4 mapped IPv6 case, packet
is IPv4 and template is IPv6. Fix this by using the addresses
from the template unconditionally.

On systems where some controllers get a dynamic ID assigned and some have
a fixed number from DT, the current implemention might run into an IDR
collision if the dynamic controllers gets probed first and get an IDR number,
which is later requested by the controller with the fixed numbering. When
this happens the fixed controller will fail to register with the SPI core.
Fix this by skipping all known alias numbers when assigning the dynamic IDs.

In case of a hardware restart the BA session data in HW is lost
so the reorder buffer simply passes the frames to mac80211 as is
as there is no NSSN set. Instead, we will drop these frames
before they reach the reorder buffer. mac80211 drops such frames anyway,
but we shouldn't rely on that. In addition it saves some

The RCU lifetime on baid_data is unclear, so this adds a direct copy of the

Currently we return early from sync_rx_queues for a000 devices.
This may cause, in case of a non-empty reorder buffer, a warning
later on since the RX queue isn't getting the notification to
empty it.
A better approach would be to send the notification for the default
queue only.
Do this hard coded for now, until we will have the API to enable
multi queue for a000 devices.

Commit a6d24fad00d9 ("iwlwifi: pcie: dump registers when HW becomes

memory mapped registers on a failure. It is currently only accessible
within trans.c. Add it to struct iwl_trans_ops, so that failure cases
in other files can call it. While there, add a call to this function
from iwl_pcie_load_firmware_chunk in pcie/tx.c, since this is a common
failure case seen on some platforms.

When there is a reorder timeout, we may get to a situation
where we have the timeout latency for all the next 64 frames.
This happens since NSSN is behind for a while, and the driver
won't release the frames, since it is not allowed by NSSN.
As a result the frame is stored in the reorder buffer although
there is no hole, and released 100 ms later.
Add a direct comparison to the reorder buffer head, and release
immediately if possible.
For example:
Frame 0 is missed. We receive frame 1, and store it in the buffer.
After 100 ms, frame 1 is released and reorder buffer head is 2.
We then receive frame 2, with NSSN 0, and store it instead of
releasing it.

We don't plan to have products with 3 antennas in the near
future. All the rest of the code follows the same
assumption as well.
Remove the support for antenna C from rs_toggle_ant.
When trying to toggle from ANT_B, this avoids to go through
ANT_C, discover that it doesn't exist and continue to ANT_A.
In MIMO, this avoids to do ANT_AB -> ANT_BC -> ANT_AC and
back to ANT_AB.

After a FW reset on A000 NICs, the driver doesn't
set the seq number when re-allocating the queues.
This in turn leads to a mismatch between the seq
number the driver thinks each frame has, and the
actual seq num given by the HW.
This especially causes issues with aggregations,
since the driver could be waiting to start an
aggregation and queue traffic from the mac80211
until then, when actually it shouldn't be waiting.

Currently the code is mixing defines and is inconsistent.
When enabling a queue, we usually configure the scheduler
with IWL_FRAME_LIMIT - 64.
When sending to firmware the rate scaling, we limit aggregation
to LINK_QUAL_AGG_FRAME_LIMIT_DEF - 63, due to a scheduler bug.
Given that, clean up the following:
- Fix a stray queue enablement with LINK_QUAL_AGG_FRAME_LIMIT_DEF.
- Change the comparison that tests if queue needs to be reconfigured
to be compared directly to how it was configured.
This also saves the redundant round down of the buffer size just
for the sake of comparing it, making the code more readable.
- Better document gen2 logic

Stephen Smalley says:
Since 4.14-rc1, the selinux-testsuite has been encountering sporadic
failures during testing of labeled IPSEC. git bisect pointed to
commit ec30d ("xfrm: add xdst pcpu cache").
The xdst pcpu cache is only checking that the policies are the same,
but does not validate that the policy, state, and flow match with respect
to security context labeling.
As a result, the wrong SA could be used and the receiver could end up
performing permission checking and providing SO_PEERSEC or SCM_SECURITY
values for the wrong security context.
This fix makes it so that we always do the template resolution, and
then checks that the found states match those in the pcpu bundle.
This has the disadvantage of doing a bit more work (lookup in state hash
table) if we can reuse the xdst entry (we only avoid xdst alloc/free)
but we don't add a lot of extra work in case we can't reuse.
xfrm_pol_dead() check is removed, reasoning is that
xfrm_tmpl_resolve does all needed checks.

While stress testing MTU probing, we had crashes in list_del() that we root-caused
to the fact that tcp_fragment() is unconditionally inserting the freshly allocated
skb into tsorted_sent_queue list.
But this list is supposed to contain skbs that were sent.
This was mostly harmless until MTU probing was enabled.
Fortunately we can use the tcp_queue enum added later (but in same linux version)
for rtx-rb-tree to fix the bug.
