ath10k_dbg() is called in ath10k_process_rx() with huge set of arguments
which is causing CPU overhead even when debug_mask is not set.
Good improvement was observed in the receive side performance when call
to ath10k_dbg() is avoided in the RX path.

Since currently all debug messages are sent via tracing infrastructure,
we cannot entirely avoid calling ath10k_dbg. Therefore, call to
ath10k_dbg() is made conditional based on tracing config in the driver.

Trasmit performance remains unchanged with this patch; below are some
experimental results with this patch and tracing disabled.

I was really surprised that the IPv6 mtu exception followed by redirect
test was passing as nothing about the code suggests it should. The problem
is actually with the logic in the test script.

Fix the test cases as follows:
1. add debug function to dump the initial and redirect gateway addresses
   for ipv6. This is shown only in verbose mode. It helps verify the
   output of 'route get'.

2. fix the check_exception logic for the reset case to make sure that
   for IPv4 neither mtu nor redirect appears in the 'route get' output.
   For IPv6, make sure mtu is not present and the gateway is the initial
   R1 lladdr.

3. fix the reset logic by using a function to delete the routes added by
   initial_route_*. This format works better for the nexthop version of
   the tests.

While improving the test cases, go ahead and ensure that forwarding is
disabled since IPv6 redirect requires it.

Also, runs with kernel debugging enabled sometimes show a failure with
one of the ipv4 tests, so spread the pings over longer time interval.

The end result is that 2 tests now show failures:

TEST: IPv6: mtu exception plus redirect                    [FAIL]

and the VRF version.

This is a bug in the IPv6 logic that will need to be fixed
separately. Redirect followed by MTU works because __ip6_rt_update_pmtu
hits the 'if (!rt6_cache_allowed_for_pmtu(rt6))' path and updates the
mtu on the exception rt6_info.

MTU followed by redirect does not have this logic. rt6_do_redirect
creates a new exception and then rt6_insert_exception removes the old
one which has the MTU exception.

PHY drivers don't have to and shouldn't fiddle with phylib internals.
Most of the code in bcm87xx_config_init() can be removed because

In addition I replaced usage of PHY_10GBIT_FEC_FEATURES with an
implementation of the get_features callback. PHY_10GBIT_FEC_FEATURES
is used by this driver only and it's questionable whether there
will be any other PHY supporting this mode only. Having said that

inet: frags: avoid possible races at netns dismantle

This patch series fixes a race happening on netns dismantle with
frag queues. While rhashtable_free_and_destroy() is running,
concurrent timers might run inet_frag_kill() and attempt
rhashtable_remove_fast() calls. This is not allowed by
rhashtable logic.

Since I do not want to add expensive synchronize_rcu() calls
in the netns dismantle path, I had to no longer inline
netns_frags structures, but dynamically allocate them.

The ten first patches make this preparation, so that
the last patch clearly shows the fix.

As this patch series is not exactly trivial, I chose to
target 5.3. We will backport it once soaked a bit.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

syszbot found an interesting use-after-free [1] happening
while IPv4 fragment rhashtable was destroyed at netns dismantle.

While no insertions can possibly happen at the time a dismantling
netns is destroying this rhashtable, timers can still fire and
attempt to remove elements from this rhashtable.

This is forbidden, since rhashtable_free_and_destroy() has
no synchronization against concurrent inserts and deletes.

Add a new fqdir->dead flag so that timers do not attempt
a rhashtable_remove_fast() operation.

We also have to respect an RCU grace period before starting
the rhashtable_free_and_destroy() from process context,
thus we use rcu_work infrastructure.

This is a refinement of a prior rough attempt to fix this bug :
https://marc.info/?l=linux-netdev&m=153845936820900&w=2

Since the rhashtable cleanup is now deferred to a work queue,
netns dismantles should be slightly faster.

qed*: Improve performance on 100G link for offload protocols

This patch series modifies the current implementation of PF selection.
The refactoring of the llh code enables setting additional filters
(mac / protocol) per PF, and improves performance for offload protocols
(RoCE, iWARP, iSCSI, fcoe) on 100G link (was capped at 90G per single
PF).

Improved performance on 100G link is achieved by configuring engine
affinty to each PF.
The engine affinity is read from the Management FW and hw is configured accordingly.
A new hw resource called PPFID is exposed and an API is introduced to utilize
it. This additional resource enables setting the affinity of a PF and providing
more classification rules per PF.
qedr,qedi,qedf are also modified as part of the series. Without the
changes functionality is broken.

  for setting the iwarp_cmt mode. Additional patch added to the series for
  adding the devlink support.

- Fix kbuild test robot warning on qed_llh_filter initialization.

- Remove comments inside function calls

Add iWARP engine affinity setting for supporting iWARP over 100g.
iWARP cannot be distinguished by the LLH from L2, hence the
engine division will affect L2 as well. For this reason we add
a parameter to devlink to determine the engine division.

The table currently contains a single parameter for
configuring whether iWARP should be enabled on a 100g
device. Enabling iWARP on a 100g device impacts L2
performance and is therefore not enabled by default.

In 100g mode the doorbell bar is united for both engines. Set
the correct offset in the hwfn so that the doorbell returned
for RoCE is in the affined hwfn.

Use the msix vectors of the affined hwfn and not the
leading one.
