Readers may note that this does not initialize the

As USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS, beacon interrupt

zd1211rw: handle lost read-reg interrupts
Device losses read-reg interrupts. By looking at usbmon it appears that
USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS. This causes read
command to timeout, usually under heavy TX.
Fix by retrying read registers again if USB_INT_ID_RETRY_FAILED is received
while waiting for USB_INT_ID_REGS.
However USB_INT_ID_REGS is not always lost but is received after
USB_INT_ID_RETRY_FAILED and is usually received by the retried read
command. USB_INT_ID_REGS of the retry is then left unhandled and might
be received by next read command. Handle this by ignoring previous
USB_INT_ID_REGS that doesn't match current read command request.

netlink: advertise incomplete dumps
Consider the following situation:
* a dump that would show 8 entries, four in the first
round, and four in the second
* between the first and second rounds, 6 entries are
removed
* now the second round will not show any entry, and
even if there is a sequence/generation counter the
application will not know
To solve this problem, add a new flag NLM_F_DUMP_INTR
to the netlink header that indicates the dump wasn't
consistent, this flag can also be set on the MSG_DONE
message that terminates the dump, and as such above
situation can be detected.
To achieve this, add a sequence counter to the netlink
callback struct. Of course, netlink code still needs
to use this new functionality. The correct way to do
that is to always set cb->seq when a dumpit callback
is invoked and call nl_dump_check_consistent() for
each new message. The core code will also call this
function for the final MSG_DONE message.
To make it usable with generic netlink, a new function
genlmsg_nlhdr() is needed to obtain the netlink header
from the genetlink user header.

ath9k_hw: make sure PAPRD training is properly done
checking the status of PAPRD_AGC2_POWER(Log(ADC_power) measured after
last gain-change in dB) field suggests whether the PAPRD is completely/properly
done. This is an additional check apart from polling for PAPRD done bit being set.
Susinder suggests that the ideal power range value should be
0xf0 to 0xfe. With AR9382 we do have the values in this range. to have a
common check for all platforms we take agc2_power should be atleast greater
than 0xe0

ath9k: Fix a corner case failure in sending PAPRD frames in HT40
when the AP is configured with HT40/2.4GHz and when PAPRD is enabled in station
we have PAPRD training frames never sent out because of the following
failure "PAPRD target power delta out of range". This consistently happens
in channel 10,11 in Over The Air testing and rarely in channel 6 under wired
