Firmware will report flag with HTT_RX_IND_MPDU_STATUS_TKIP_MIC_ERR
if MIC error, the flag will be used in mac80211.
ieee80211_rx_h_michael_mic_verify will check the flag and start TKIP
countermeasures.
Now countermeasure tests pass both with WPA only and WPA2/WPA mixed
mode.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00007-QCARMSWP-1.

This patch will add the support to control the transmit power for traffic
to a station associated with the AP.
Underlying firmware will enforce that the maximum tx power will be based
on the regulatory requirements. If the user given transmit power is greater
than the allowed tx power in the given channel, then the firmware will use
the maximum tx power in the same channel.
Max and Min tx power values will depends on no of tx chain masks,
for QCA9984 allowed tx power range values from 6 to 23.
When 0 is sent to the firmware as tx power, it will revert to the default
tx power for the station.

Peer creation in firmware fails if last peer deletion is still
in progress.
The firmware sends a peer delete response event if it advertises
the service WMI_SERVICE_SYNC_DELETE_CMDS. This peer delete response
event is used to synchronize the peer deletion.
Add peer delete response event and wait for the event after
deleting every peer from host driver to synchronize with firmware.

When we add an interface immediately after removing
the interface the vdev deletion in firmware might not
have been completed. We need to synchronize the vdev creation
with the firmware.
Wait for vdev delete response from firmware when we

Observed PCIE device wake up failed after ~120 iterations of
soft-reboot test. The error message is
"ath10k_pci 0000:01:00.0: failed to wake up device : -110"
The call trace as below:
ath10k_pci_probe -> ath10k_pci_force_wake -> ath10k_pci_wake_wait ->
ath10k_pci_is_awake
Once trigger the device to wake up, we will continuously check the RTC
state until it returns RTC_STATE_V_ON or timeout.
But for QCA99x0 chips, we use wrong value for RTC_STATE_V_ON.
Occasionally, we get 0x7 on the fist read, we thought as a failure
case, but actually is the right value, also verified with the spec.
So fix the issue by changing RTC_STATE_V_ON from 0x5 to 0x7, passed
~2000 iterations.

Currently, below fixed rate commands are broken,
iw wlanx set bitrates legacy-<2.4|5> ht-mcs-<2.4|5> vht-mcs-<2.4|5> \
<NSS:MCSx>
iw wlanx set bitrates legacy-<2.4|5> <legacy rate> ht-mcs-<2.4|5> \
vht-mcs-<2.4|5> <NSS:MCSx>
There are two methods to set fixed rate, both failed,
- Use vdev fixed rate command
This command only support one single rate, but it's broken due to
mac80211 change commit e8e4f5280ddd ("mac80211: reject/clear user
rate mask if not usable"), which requires user to specify at least
one legacy rate. So we can't use this command to set ht/vht single
rate any more.
- Use peer_assoc command
This command can update rx capability for multiple rates, it will
work fine for ht mcs rates, as each supported mcs can be advertised
in ht_mcs index mask. But this will not work with vht rates because,
as per the vht mcs capability advertisement, there are only two bits
to indicate the supported mcs. E.g. only support 0-7, 0-8, 0-9.
So introduced new WMI command: WMI_PEER_PARAM_FIXED_RATE. After peer
assoc, the peer fixed rate cmd will work for that specific peer.
Remaining peers will use auto rate. If both vdev fixed rate and peer
fixed rates are given, peer fixed rate will take effect to peers for
which this cmd is given. Remaining peers in that vdev, will use vdev
fixed rate.

On SMP platform, when continuously running wifi up/down, the napi
poll can be scheduled during chip reset, which will call
ath10k_pci_has_fw_crashed() to check the fw status. But in the reset
period, the value from FW_INDICATOR_ADDRESS register will return
0xdeadbeef, which also be treated as fw crash. Fix the issue by
moving chip reset after napi disabled.

For QCA988X target, pktlog gives details of the tx bitrate
which is used in the driver for station info.
Enabling pktlog by default will cause more interrupts
in target to host CE pipe, which can impact more CPU usage
for targets ex:WCN3990 and also not required for all other
platforms (eg: WCN3990), for getting tx bitrate.
Enable pktlog only for QCA988X based on hardware params.

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
phylib takes care.
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
in one of the next kernel versions we may decide to remove it.

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.

Following patch will add rcu grace period before fqdir
rhashtable destruction, so we need to dynamically allocate
fqdir structures to not force expensive synchronize_rcu() calls
in netns dismantle path.

fqdir will soon be dynamically allocated.
We need to reach the struct net pointer from fqdir,
so add it, and replace the various container_of() constructs
by direct access to the new field.

lowpan_frags_ns_sysctl_register() can perform the needed initialization

1) struct netns_frags is renamed to struct fqdir
This structure is really holding many frag queues in a hash table.
2) (struct inet_frag_queue)->net field is renamed to fqdir
since net is generally associated to a 'struct net' pointer
in networking stack.

The FEC capbility may be changed with port speed changes. Driver
needs to read the active FEC mode, and update FEC capability
when port speed changes.

This patch adds aRFS support for PF. The aRFS rules are also
stored in the hardware flow director table, Use the existing
filter management functions to insert TCPv4/UDPv4/TCPv6/UDPv6
flow director filters. To avoid rule conflict, once user adds
flow director rules with ethtool, the aRFS will be disabled,
and clear exist aRFS rules. Once all user configure rules were
removed, aRFS can work again.

Allocate CPU rmap and add entry for each irq. CPU rmap is
used in aRFS to get the queue number of the rx completion
interrupts.
In additional, remove the calling of
irq_set_affinity_notifier() in hns3_nic_init_irq(), because
we have registered notifier in irq_cpu_rmap_add() for each
vector, otherwise it may cause use-after-free issue.
