It is uneeded since Johannes removed the HUGE flag. The DMA mapping is always held in the same index as the command.

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
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.

Now, there are only two functions to send a host command:
* send_cmd that receives a iwl_host_cmd
* send_cmd_pdu that builds the iwl_host_cmd itself and received flags
The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API
functions.
Kill the unused flags CMD_SIZE_NORMAL / CMD_NO_SKB on the way.

mac80211 maintains a running average of the RSSI when a STA
is associated to an AP. Report threshold events to any driver
that has registered callbacks for getting RSSI measurements.
Implement callbacks in mac80211 so that driver can set thresholds.
Add callbacks in mac80211 which is invoked when an RSSI threshold
event occurs.

From: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com>
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.

This causes a compile warning because iwl_testmode_cmd() has
struct nlattr *tb[IWL_TM_ATTR_MAX - 1];
and the -1 shouldn't be there.

For testing purpose, we need better control of msc from user application.
Separate the fixed_rate between debugfs and testmode and enforce it.
