fc8f0456dc mwifiex: disable UAPSD mode when AP starts
When AP is started, firmware exits power save mode. This
means power save manager of AP takes priority over station.
Firmware stop sending periodic AWAKE events to host.

We may have UAPSD enabled on station which buffers data
packets until AWAKE event from firmware. Data path is
unnecessarily blocked in this case. This patch disables
UAPSD mode to reenable transmit data path.

0ea3186ce0 mwifiex: fix NULL packet downloading issues
This patch makes sure that skb is freed after downloading
NULL packet in error cases. Also, USB chipsets return
-EINPROGRESS after downloading packets, they are freed in
USB completion handler later. We will add missing change
to set tx_lock_flag for USB which blocks further packets.

7d652034d1 mwifiex: channel switch support for mwifiex
This patch adds cfg80211 channel_switch support for mwifiex.
Upon receiving channel switch request, driver would parse channel
switch announcement IE from beacon_data.
If TX is blocked, netdev queues are stopped. IEs from csa_beacon
are then parsed and set to FW.

b51f3beecf cfg80211: change bandwidth reporting to explicit field
For some reason, we made the bandwidth separate flags, which
is rather confusing - a single rate cannot have different
bandwidths at the same time.

Change this to no longer be flags but use a separate field
for the bandwidth ('bw') instead.

While at it, add support for 5 and 10 MHz rates - these are
reported as regular legacy rates with their real bitrate,
but tagged as 5/10 now to make it easier to distinguish them.

In the nl80211 API, the flags are preserved, but the code
now can also clearly only set a single one of the flags.

 * add NL80211_STA_INFO_RX_DROP_MISC which exists internally

4f3dfdfb4c mwifiex: get supported BA stream info from FW
This patch adds support to get number of BA streams
supported information from FW. Some newer chips(e.g. 8897 series)
support 4 BA streams for TX; so driver should not disallow BA stream
setup just after 2 streams have been established.

2ab87d5d67 mwifiex: do not send key material cmd when delete wep key
This patch fixes memory corruption reported by community developer.

"Memory corruption occurs in mwifiex_ret_802_11_key_material_v1()
when a short command response is received without a key length
causing non initialised memory to be interpreted as the key
length resulting in a memcpy() overwriting the part of the
driver's private data structure beyond the key area."

For v1 key material API firmwares, there is no need to send
command to delete WEP key. WEP encryption/decryption is controlled
by mac_control command.

This patch avoids sending key material command in del_key case.

0b4155d1cc mwifiex: module parameter for deep sleep configuration
This patch adds module parameter for auto deepsleep configuration.
By default, module_param is 0 and auto deep sleep is enabled.
If mwifiex driver is loaded with disable_auto_ds=1, deep sleep
configuration would not be downloaded to FW and FW would not enter
deepsleep upon initializing.
