cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flag
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set
maximum available bandwidth should be calculated base on
contiguous rules and wider channels will be allowed to cross
multiple contiguous/overlapping frequency ranges.
In case of old kernels maximum bandwidth from regulatory
rule will be used, while there is no NL80211_RRF_AUTO_BW flag.
This fixes the previous commit
9752482083066af7ac18a5ca376f

mwifiex: don't leak DMA command skbuffs
The current mwifiex pcie driver assumed that it would get
its cmdrsp_complete() callback called before another command
was sent to unmap the command's skbuff. However, that is not
true. The mwifiex_check_ps_cond() will send a sleep command
to the card without having adapter->curr_cmd set. Within the
workqueue's state machine the adapter's state would be set
to allow commands (curr_cmd = NULL && cmd_sent = false) after
having receieved the response from the sleep command. The
card->cmd_buf would then be overridden with the new command
but the first command's skbuff was not unmapped. This leaks
mapped skbuffs when a bounce buffer is employed.
To rectify this unmap the card->cmd_buf when the response is
received from the card instead of waiting for the

It is known to be buggy and has less than optimal performance

reason that it was kept when we made the switch to minstrel
as default was that it showed higher throughput numbers in a
clean/ideal environment.
This is no longer the case and minstrel can push ath9k to
the same throughput levels. In TCP, with 3-stream cards, more than
295 Mbps can be obtained in open air, with 2-stream cards,
210 Mbps is easily reached. To test performance issues,
instead of using a broken rate control module, it is better

brcmfmac: remove TRACE level debug message from brcmf_sdio_bus_sleep()
The function brcmf_sdio_bus_sleep() function is called rather
frequently, which fills the log when TRACE level is enabled. Reduced
the level to SDIO.

brcmfmac: on sdio remove first detach bus then stop worker.
Currently the function sdio_remove will first destroy the datawork
workqueue and then detach the bus. This can create the situation
where work gets added on non-existing work queue resulting in panic.

brcmfmac: simplify sdio code download routine.
brcmf_sdio_download_code_file is using a loop to send small blobs
of data. This is unnecessarily complex and was simplified with this
patch.

brcmfmac: fix sdio sending of large buffers.
the function brcmf_sdiod_ramrw is supposed to be able to send
large blobs of data. However inside the loop the skb->len field
did not correctly get reset each round. As a result only small
blobs could be sent. This patch fixes this problem.
