The zd1211rw always assumed that the storage device is at endpoint 1,
but there are devices (Spairon Homelink 1202) that are at endpoint 0.
Try both, starting with 1 to make sure to not break existing setups.

Since mac80211_hwsim supports multiple virtual interfaces, we need to
iterate through all active interfaces when figuring out whether there
is a match during TX Ack status checking. This fixes TX status

mesh_autostart_enabled was nowhere set. Rumor is that this is used in the

Enable spatial multiplexing in mac80211 by telling the
driver what to do and, where necessary, sending action
frames to the AP to update the requested SMPS mode.
Also includes a trivial implementation for hwsim that
just logs the requested mode.
For now, the userspace interface is in debugfs only,
and let you toggle the requested mode at any time.

According to Ralink source code, the RX frame format is RXINFO + RXWI +
802.11 frame + RXD, including various padding. Before this patch, we
were using RXD + RXWI + 802.11 frame, so RXD was not correct.
Doing this, we fix the L2PAD bit which is now correctly set on received
frames.

RX aggregation is a way to receive multiple 802.11 frames in one RX buffer.
However, we don't know yet how to handle this case in rt2800usb_fill_rxdone
and this has probably no impact on RX performance as well, so we disable it

Simplify the rt2x00queue_insert_l2pad function by handling the alignment
operations one by one. Do not special case special circumstances.
Basically first perform header alignment, and then perform payload alignment
(if any payload does exist). This results in a properly aligned skb.
The end result is better readable code, with better results, as now L2 padding
is inserted only when a payload is actually present in the frame.

With the improved L2 padding code, this flag is no longer necessary, as the
rt2x00queue_remove_l2pad is capable of detecting by itself if L2 padding is
applied.

Fix a couple of more bugs in the L2 padding code:
1. Compute the amount of L2 padding correctly (in 3 places).
2. Trim the skb correctly when the L2 padding has been applied.
Also introduce a central macro the compute the L2 padding size.

Otherwise we end up truncating the skb before removing the l2pad
thus we might have the truncated part become garbage while getting
it back in remove_l2pad.
For the same issue: remove the skb_trim from the rt2800 fill_rxdone
(it is done after l2pad removal in rt2x00lib_rxdone).

Do not need to log error when fail the sensitivity command, driver will send
sensitivity write command to uCode after each sensitivity calibration if
station is associated with AP. It is a normal case when user unload the module
or shutdown the system while still associated with the AP, since uCode already
on the way down, it will not reply the sensitivity write request; report
error in this case will give misleading information, remove the error checking
here to provide a clean shutdown if no other error detected.

In order to help uCode debugging, adding the capability to provide
continuous uCode event logging function.
uCode events is located in round-robin event queue and filled by uCode,
by enable continuous event logging, driver check the write pointer
and log the newly added events in iwl_bg_ucode_trace() timer function.
There is still possibility of missing events if event queue being
wrapped before next event dump; but with this capability, we can have
much better understanding of the uCode behavior during runtime; it can
help to debug the uCode related issues.
Methods to enable/disable the continuous event log:
step 1: enable ucode trace timer
"echo 1 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"
step 2: start ftrace
sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d
step 3: stop ftrace
sudo ./trace-cmd report trace.dat
step 4: disable ucode trace timer
"echo 0 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"
use "ucode_tracing" debugfs file to display number of event
queue wrapped when driver attempt the continuous event logging. If event
queue being wrapped more than once when driver has opportunity to log
the event; it indicated there are events missing in the event log trace.
This continuous event log function only available for 4965 and newer
NICs.
