When wide band scan is enabled, host configures all possible
channels with all possible phy modes. In his case if a scan
is invoked with 0 channels, target will end up scanning each
channel with all possible phy modes which increases scan time
exponentially.
If wide band scan is enabled and scan is issues with 0 channels,
configure target to scan all available channels only in 11A/11G mode.

Do command complete before invoking scan event handlers.
Its required as few scan event handlers check if scan is

complete is not done yet.

Due to Rx sensitivity issue, sometime beacons are seen on adjacent
channel so workaround in software is needed. If DS params or HT
info are present driver can get proper channel info from these IEs
and set channel_mismatch so that the older RSSI values are used in
new entry.
For the cases where DS params and HT info is not present, driver
needs to check below conditions to get proper channel and set
channel_mismatch so that the older RSSI values are used in
new entry:
-- The old entry channel and new entry channel are not same
-- RSSI is less than -80, this indicate that the signal has
leaked in adjacent channel

For each scan node in db, real delete should be called only once.
If 2 threads are trying to delete a note, only one thread should
mark it delete and decrement the ref count and the other thread
should return. or use after free happens as some other thread is

When a beacon/probe resp is received the scan cache delete the
old node (N1) and adds a new node(N2) at the end of the list, If any
other process is using old node (N1), for some amount of time driver
will have 2 entry for the same AP. Now if driver again receive a
beacon/probe resp during this time, it end up deleting the older node
(N1) Again and thus making its ref count 0 and freeing it, even when
the process using old node (N1) hasnt freed it.
To fix this add a active state to the scan node, and mark it inactive
or logically delete the node as soon its deleted from ageout, entry update
or flush logic. Also do not use the inactive or logically deleted node
for any new operation. For this add a logic to return only active nodes in
scm_get_next_node.
