We block TX queues for particular RA list depending upon channel
switch state. If channel switch state is moving to base channel,
we unblock RA lists for AP. If channel switch state is moving to off

If tx_pkts_queued is increased for tx paused receive address, tx process
will be triggered for this packet. But since RA list was tx paused,
there will be an infinite loop in mwifiex_wmm_process_tx waiting for the
event(tx pause, tdls cs) to cancel tx pause. This will be an dead loop,
since main_process was locked at this time, there will be no opportunity
to process event.

So do not increase tx_pkts_queued if receive address tx paused,
this will be restored RA list is unpaused.

Major changes in ath10k:

* enable VHT for IBSS
* initial work to support qca99x0 and the corresponding 10.4 firmware branch

FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.

A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range

The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

Further testing proved that multi-channel AP+STA

====================
be2net: patch set

Hi David, the following patch set has code cleanup patches, minor enhancements
and non-critical fixes. Pls consider applying to the net-next tree. Thanks!

Patch 1 removes duplicate code in be_setup_wol() routine making it simpler
and more readable.

Patch 2 fixes the the bridge mode return value for the ndo_bridge_getlink()
call. Instead of just relying on the SRIOV enabled state, the driver now
queries the FW, for the actual mode of bridge.

Patch 3 removes code for setting D0 power state as it's already done
in pci_enable_device()

Patch 4 fixes a bad return value in be_check_ufi_compatibility() routine
introduced by an earlier commit.

Patch 5 fixes a field in udp header being accessed while in network endian
format.

Patch 6 fixes the be_mcc_notify() routine to return an error status when
the FW/HW is in an error state.

Patch 7 fixes the be_cmd_rx_filter() routine to issue the RX_FILTER cmd
and not wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.

Patch 8 fixes the be_cmd_set_loopback() routine to issue the LOOPBACK cmd
and not wait for the FW completion while spin_lock_bh() is held on the
mcc_lock. As the cmd is always issued from ethtool in a process context,
it can sleep till the FW completion is received.

Patch 9 bumps up the driver version to 10.6.0.3

The SET_LOOPBACK_MODE command is always issued from ethtool only in a
process context. So, while waiting for the cmd to complete, the driver
can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
only after the cmd completes while the MCCQ is locked).

Non-local binds are very useful in emulating the Internet in a box, etc.

This add the ip_nonlocal_bind sysctl under ipv6.

ip -6 route add local 2001:0:0:1::/64 dev lo proto kernel scope host table 200
sysctl -w net.ipv6.ip_nonlocal_bind=1
