Subject: [PATCH V2 1/1] mwifiex: add tx info to skb when forming mgmt frame

From: Huawei Yang <harvey.huawei.yang@...il.com>

In function 'mwifiex_write_data_complete' it need tx info to find
the mwifiex_private to updates statistics and wake up tx queues.
Or we may trigger tx queues timeout when transmitting lots of mgmt
frames.
