mac80211: use nullfunc instead of probe request for connection monitoring
nullfunc frames are better for connection monitoring, because probe requests
are answered even if the AP has already dropped the connection, whereas
nullfunc frames from an unassociated station will trigger a disassoc/deauth
frame from the AP (WLAN_REASON_CLASS3_FRAME_FROM_NONASSOC_STA), which allows
the station to reconnect immediately instead of waiting until it attempts to
transmit the next unicast frame.
This only works on hardware with reliable tx ACK reporting, any other hardware
needs to fall back to the probe request method.

mac80211: Disable hw crypto for GTKs on AP VLAN interfaces
When using AP VLAN interfaces, each VLAN interface should be in its own
broadcast domain. Hostapd achieves this by assigning different GTKs to
different AP VLAN interfaces.
However, mac80211 drivers are not aware of AP VLAN interfaces and as
such mac80211 sends the GTK to the driver in the context of the base AP
mode interface. This causes problems when multiple AP VLAN interfaces
are used since the driver will use the same key slot for the different
GTKs (there's no way for the driver to distinguish the different GTKs
from different AP VLAN interfaces). Thus, only the clients associated
to one AP VLAN interface (the one that was created last) can actually
use broadcast traffic.
Fix this by not programming any GTKs for AP VLAN interfaces into the hw
but fall back to using software crypto. The GTK for the underlying AP
interface is still sent to the driver.
That means, broadcast traffic to stations associated to an AP VLAN
interface is encrypted in software whereas broadcast traffic to
stations associated to the non-VLAN AP interface is encrypted in
hardware.

cfg80211: Fix regulatory bug with multiple cards and delays
When two cards are connected with the same regulatory domain
if CRDA had a delayed response then cfg80211's own set regulatory
domain would still be the world regulatory domain. There was a bug
on cfg80211's logic such that it assumed that once you pegged a
request as the last request it was already the currently set
regulatory domain. This would mean we would race setting a stale
regulatory domain to secondary cards which had the same regulatory
domain since the alpha2 would match.
We fix this by processing each regulatory request atomically,
and only move on to the next one once we get it fully processed.
In the case CRDA is not present we will simply world roam.
This issue is only present when you have a slow system and the
CRDA processing is delayed. Because of this it is not a known
regression.
Without this fix when a delay is present with CRDA the second card
would end up with an intersected regulatory domain and not allow it
to use the channels it really is designed for. When two cards with
two different regulatory domains were inserted you'd end up
rejecting the second card's regulatory domain request.
This fails with mac80211_hswim's regtest=2 (two requests, same alpha2)
and regtest=3 (two requests, different alpha2) module parameter
options.
This was reproduced and tested against mac80211_hwsim using this
CRDA delayer:
#!/bin/bash
echo $COUNTRY >> /tmp/log
sleep 2
/sbin/crda.orig
And these regulatory tests:
modprobe mac80211_hwsim regtest=2
modprobe mac80211_hwsim regtest=3

When send out skb data to mac80211, orignal code will cause mac80211

rt2x00: Fix rt2800 USB TX Path DMA issue
rt2800usb chips need to add 1~3 bytes zero padding after each 802.11 header & payload,
and at the end need to add 4 bytes zero padding whether doing TX bulk aggregation or not,
TXINFO_W0_USB_DMA_TX_PKT_LEN in TXINFO must include 1-3 bytes padding after 802.11 header & payload
but do not include 4 bytes end zero padding.
In rt2800usb_get_tx_data_len do not consider multiple of the USB packet size case, sometimes this will
cause USB DMA problem.

Also remove the indications of non functional support for rt27xx/rt28xx/rt30xx

For some hardware the REGISTER_BUSY_COUNT isn't sufficient,
increase the REGISTER_BUSY_COUNT to 100 to catch most
devices which have more problems with accessing the registers.
For normal operating devices nothing would change as they will
exit the loop early anyway.
