WiFi throughput drops drastically when BT is turned on, BT and WiFi
are simultaneously transmitting/receiving traffic. This is particularly true
when BT has higher priority over WiFi, and hence the device defers TX frames.
The AP assumes that the channel is bad and reduces the data rate, implying
longer airtime, which exacerbates the problem further, resulting ultimately
in what is popularly called the "death-spiral" phenomenon. The use of PS-poll
in such scenarios guarantees a low but consistent throughput.
Since the death-spiral phenomenon is observed only when the RSSI is low, use
PS-poll only when RSSI is low and disable when high, with a known hysterisis.
This feature specifies the high and low thresholds and implements the
callbacks registered with mac80211, which will be called when threshold events
occur.

Tx free functions move to the transport layer. Unify the functions that deal with tx queues and cmd queue.
Since the CMD queue is not fully allocated, but uses the q->n_bd / q->window trick, the release flow of TX queue and CMD queue was different.
iwlagn_txq_free_tfd receives now the index of the TFD to be freed, which allows to unify the release flow for all the queues.

In XMIT path, the skb that we get from the kernel itself is not
aligned with 4-byte boundary on some embedded platforms.
Had it not been the presence of tx_pkt_offset field in txpd, 4 byte
memory alignment was not possible without memmove of entire skb.
And that would have increased MIPS instead of reducing.
With this patch few memory cycles can be saved while fetching
interface header and txpd structure because of 4 bytes memory
alignment.

Debugfs command 'info' shows wrong interface type. The regression
occurred due to commit eecd8250e (mwifiex: remove MWIFIEX_BSS_MODE_
macros) in which we replaced MWIFIEX_BSS_MODE_* macros by
NL80211_IFTYPE_*, for example,
MWIFIEX_BSS_MODE_IBSS (2) --> NL80211_IFTYPE_ADHOC (1)
The issue is fixed by swapping static character array used to
display interface type information.
