ieee80211_rx_status.flags is full. Define a new vht_flag
variable to be able to set more VHT related flags and make
room in flags.

We should check MIC error flag base on
rx_attention, to have consistent status
of MIC failure and FCS error.

Too much of tx info was being cleared. This caused
issues in some setups with tx frame status
reporting.
This should fix some cases of stations not being
able to associate to ath10k AP.

Garbage was reported in ieee80211_tx_info. This
led to a WARN_ON in cfg80211_calculate_bitrate().
This also fixes some random tx bitrate values
reported through `iw` command.

With commit 0cfcefef1 ("mac80211: support reporting A-MSDU subframes
individually") there's no need to have the hack to clear the retry bit in
ath10k_htt_rx_amsdu(), mac80211 can handle this properly now.

NSTS values reported in the VHT-SIG-A1 are 0
through 7 but they actually describe number of
streams 1 through 8.
1SS frames were dropped. This patch fixes this.

HW reports each A-MSDU subframe as a separate
sk_buff. It is impossible to configure it to
behave differently.
Until now ath10k was reconstructing A-MSDUs from
subframes which involved a lot of memory
operations. This proved to be a significant
contributor to degraded RX performance.

Instead of allocating sk_buff for a mere 16-byte
tx fragment list buffer use headroom of the
original msdu sk_buff.
This decreases CPU cache pressure and improves
performance.
Measured improvement on AP135 is 560mbps ->
590mbps of UDP TX briding traffic.

Until now the all MSDU transfer related structures
were freed when all resources were unreferenced.
Now HTC transfer is freed independently and HTT
transfer is so too.
This yields a way more simpler ath10k_skb_cb and
should possibly enable parallel pipe processing
(which is now serialized in
ath10k_pci_process_ce routine).

This reduces number of memory accesses and
hopefully contributes to better performance in the
future.

It's more efficient to simply check num_pending_tx
value instead of traversing whole bitmap of
msdu ids.

Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.
The wiki page for the driver is:
http://wireless.kernel.org/en/users/Drivers/ath10k
The driver has had many authors, they are listed here alphabetically:
