Currently, data rate for management tx packets is filled only as
1 or 6 Mbps which is wrong.
Sniffer expect data rate multiple of 2. Hence fill the data rate with
multiple of 2 for tx management packets which received from firmware
and converting into mbps.

Currently, packet capture packets are processed until the mon list
is empty. There can be situation that while mon list is not empty and
mon thread is running, mon interface is deleted and as part of it
PKT_CAPTURE_REGISTER_EVENT is cleared. After clearing the bit, interface
deletion will wait for completion of mon_register_event and flush the
remaining packets in mon list without processing them. In this case
as mon thread is already running and processing the packets from mon list
without check for PKT_CAPTURE_REGISTER_EVENT bit, it may lead to
timeout in deletion of mon interface in case of high throughput scenarios.
To avoid this situation, add a check to test PKT_CAPTURE_REGISTER_EVENT
each time before processing a packet from mon list.

Ppdu_stats are received from firmware in softirq context.
While inserting the ppdu_stats into a qdf list, a spinlock
is held for its access, same qdf list is accessed by mon
thread using spinlock. There can be a scenario in which
mon_thread held spinlock for accessing qdf_list and is
interrupted by softirq in which ppdu_stats are received.
This leads to softirq spinning for lock forever leading
to deadlock.
To address this issue, use spin_lock_bh instead of spin_lock.
Also reduce the time for which lock is taken to access the list
for insertion and removal of ppdu_stats.
