Currently whenever rts thresold is set, every packet will use RTS
protection no matter its size exceeds the threshold or not. This is
due to a bug in the rts threshold check.
	if (len > tx->local->hw.wiphy->rts_threshold) {
		txrc.rts = rts = true;
	}
Basically it is comparing an int (len) and a u32 (rts_threshold),
and the variable len is assigned as:
	len = min_t(int, tx->skb->len + FCS_LEN,
			 tx->local->hw.wiphy->frag_threshold);
However, when frag_threshold is "-1", len is always "-1", which is
0xffffffff therefore rts is always set to true.

When scanning, it is somewhat important to scan

that currently implement hw_scan only support a

Now that the mac80211 is choosing dynamic ps timeouts based on the ps-qos

If bit 29 is set, MAC H/W can attempt to decrypt the received aggregate
with WEP or TKIP, eventhough the received frame may be a CRC failed
corrupted frame. If this bit is set, H/W obeys key type in keycache.
If it is not set and if the key type in keycache is neither open nor
AES, H/W forces key type to be open.  But bit 29 should be set to 1
for AsyncFIFO feature to encrypt/decrypt the aggregate with WEP or TKIP.

TX interrupt mitigation reduces the number of interrupts
by addressing several interrupt actions (AR_IMR_TXOK,
AR_IMR_TXDESC) all in one interrupt so when enabling
it discard setting the other interrupts.

Without this TX interrupt mitigation would actually
increase the number of interrupts two-fold. We still
leave TX interrupt mitigation disabled as it is still
being tested.
