e9f21d4036 mwifiex: remove CMD_F_CANCELED flag
CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
case it already started or starts processing the cmd.
But this was probably not working the way intended:
- it is racy: mwifiex_process_cmdresp might already have passed that
  test and is continuing to use the cmd node being recycled
- mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
  we just set to NULL
- mwifiex_recycle_cmd_node will clear the flag

The reason why it probably works is that mwifiex_cancel_pending_ioctl
is only called from mwifiex_cmd_timeout_func, where the there is little
chance of a command response still arriving

92263a841b mwifiex: add SDIO rx single port aggregation
This patch brings in support for SDIO single port rx aggregation
to mwifiex.
Maximum read size support by SDIO cmd53 is 64K.
Based on multi port aggregation which is already part of mwifiex, idea here
is multiple packets received in FW can be aggregated into single buffer.
A separate upload type is defined for such packet aggregated to single port.
Packets from this single buffer are later deaggregated into individual packets.
This way, driver can receive more packets each time through single SDIO cmd53;
thereby reducing no of times MMC bus is accessed.

SDIO SP aggregation support is advertised by FW during load time and driver
would get FW block size in command response of HostCmd_CMD_SDIO_SP_RX_AGGR_CFG.

This patch adds support for TDLS management frames transmit
handler. mwifiex driver supports TDLS with external support,
i.e. expects user space application to form TDLS frames.
Same is advertised to cfg80211 during registration.

79d9a54cf0 mwifiex: advertise correct beamforming information for VHT
Currently MU/SU beamformer and MU beamformee features are
not supported.

Hence this patch modifies VHT capability information accordingly.
Number of sounding dimensions should be zero in this case.

21f58d2003 mwifiex: implement extended scan feature
In extended scan, host gets scan results through one or
multiple events instead of scan command response. Host will
send next scan command when all the events are received.

Legacy scan sometimes truncates scan results in a noisy
environment due to buffer length limitation. This issue
is addressed in extended scan.

b8b3ecec91 mwifiex: change beacon parameter structure
'mwifiex_bcn_param' structure contains five parameters which
are present in beacon buffer in case of legacy scan.

'rssi' field won't be there in this buffer for extended scan.
Hence 'bssid' and 'rssi' are removed from the structure and it is
renamed as 'mwifiex_fixed_bcn_param' so that we can have common
parsing logic later for both.
