On full reset, mci reset will put LNA update on 2G mode. And
Whenever 2g5g_switch is forced at the end of full reset, lna
update should not be skipped. Not doing so, is affecting WLAN
rx and causing beacon loss when BTCOEX is enabled on AR9462.

As soon as the interface brought up, btcoex timer starts running
eventhough the interface is in idle state and WLAN chip is moved
to full sleep mode. There is no point in running btcoex timer when
the wlan interface is in sleep mode and also it might consumes
more power on WLAN idle unassociated state. So lets stop the
btcoex when wlan is idle state.

When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.

iwlwifi: always monitor for stuck queues
If we only monitor while associated, the following
can happen:
- we're associated, and the queue stuck check
runs, setting the queue "touch" time to X
- we disassociate, stopping the monitoring,
which leaves the time set to X
- almost 2s later, we associate, and enqueue
a frame
- before the frame is transmitted, we monitor
for stuck queues, and find the time set to
X, although it is now later than X + 2000ms,
so we decide that the queue is stuck and
erroneously restart the device

On rt2x00_dmastart() we increase index specified by Q_INDEX and on
rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries
between Q_INDEX_DONE and Q_INDEX are those we currently process in the
hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can
submit to the hardware.
According to that fix rt2x00usb_kick_queue(), as we need to submit RX
entries that are not processed by the hardware. It worked before only
for empty queue, otherwise was broken.
Note that for TX queues indexes ordering are ok. We need to kick entries
that have filled skb, but was not submitted to the hardware, i.e.
started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set.
From practical standpoint this fixes RX queue stall, usually reproducible
in AP mode, like for example reported here:

If association failed due to internal error (e.g. no
supported rates IE), we call ieee80211_destroy_assoc_data()
with assoc=true, while we actually reject the association.
This results in the BSSID not being zeroed out.
After passing assoc=false, we no longer have to call
sta_info_destroy_addr() explicitly. While on it, move
the "associated" message after the assoc_success check.

we set max_prioidx to the first zero bit index of prioidx_map in
function get_prioidx.
So when we delete the low index netprio cgroup and adding a new
netprio cgroup again,the max_prioidx will be set to the low index.
when we set the high index cgroup's net_prio.ifpriomap,the function
write_priomap will call update_netdev_tables to alloc memory which
size is sizeof(struct netprio_map) + sizeof(u32) * (max_prioidx + 1),
so the size of array that map->priomap point to is max_prioidx +1,
which is low than what we actually need.
fix this by adding check in get_prioidx,only set max_prioidx when
max_prioidx low than the new prioidx.

May be due to missing lock nesting notation

.
This is a false positive, since we are indeed using 'nested' locking,
we need to use mutex_lock_nested().
Now in theory we can stack multiple MDIO multiplexers, but that would
require passing the nesting level (which is difficult to know) to
mutex_lock_nested(). Instead we assume the simple case of a single
level of nesting. Since these are only warning messages, it isn't so
important to solve the general case.

DCB and SR-IOV cannot currently be enabled at the same time as the queueing
schemes are incompatible. If they are both enabled it will result in Tx
hangs since only the first Tx queue will be able to transmit any traffic.
This simple fix for this is to block us from enabling TCs in ixgbe_setup_tc
if SR-IOV is enabled. This change will be reverted once we can support
SR-IOV and DCB coexistence.
