[PATCHv5 00/17] mwifiex patches

[Avinash Patil]

This patch series mainly adds enhancements for mwifiex AP. 
With this series, we support verbose information in station dump command
also information about AP link.
Another important enhancement is related to parsing IEs from tail of beacondata.
Few issues seen during DFS testing are also fixed in this series.
 --------
v2:
 - rebase 
v3, v4:
 - Address review comments by Bjørn & Joe. 
v5:
 - Removed reviewed-by as suggested by Joe and Julian
 -------
Avinash Patil (11):
  mwifiex: verbose logging for association failure messages
  mwifiex: correct bss_type assignment
  mwifiex: support AP reset after bss_stop
  mwifiex: enable 11d after bss reset
  mwifiex: reset 11h active flag when chandef does not require dfs

[PATCHv5 16/17] mwifiex: using right tid for addressing ra_list

[Avinash Patil]

From: Xinming Hu <huxm@marvell.com>

This patch fixes issue with the accessing correct ra_list by
downgrading corresponding tid number.

Alternatively, ra lists are created in mwifiex_wmm_add_buf_txqueue
using downgraded tid number.

[PATCHv5 17/17] mwifiex: do not decrease tx_pending for AMSDU packet once more

[Avinash Patil]

From: Xinming Hu <huxm@marvell.com>

Negative adapter->tx_pending is observed while running data traffic,
because tx_pending is decreased once more for AMSDU packet.

since tx_pending have been decreased for all the source MSDU packets,
we don't need to update once more for AMSDU packet.
