Last frame received in scan before the connect is
beacon with NULL ssid with non zero length and ssid
is sent as NULL to supplicant after association. This
will result in supplicant to trigger disconnect
casuing delay in reconnection.
Fix is to consider ssid with zeros or spaces as null
ssid.

Currently the driver calculates the nss score
based upon the max capability of the AP, and not the
hw_mde config which would be there after connection
for example, the driver calculates the score for a
2x2 11n AP, and 1x1 VHT (11ac) AP, it connects to the
11n AP in 1x1 mode, if a concurrent connection is
present, which affects throughput
Fix is to check whether the current AP channel results
in DBS or not, if yes then change the NSS to 1 instead of
2

Repeater AP failed to associate to Root AP with
hidden ssid in DFS channel.
Normally probe request is sent in passive channels if beacon
from AP is found. With strict passive scan, probe request is
not sent in passive channels even after beacon is found in that
channel.
If AP is configured in hidden ssid, Client/STA does not get the
Probe Response and thus, no SSID information is present in the
scan table to start authentication.
To overcome this, user needs to set the desired {BSSID, SSID} pair,
Example: Desired pair = {00:03:7F:AA:BB:CC, MOON1},
so that when driver receives a beacon it compares the
BSSID and updates the SSID field to update the scan table.
In general, we already set the ssid in sta configuration
But in this case, we also need to configure BSSID of the hidden AP.
This can be configured through iwpriv cmd.
Example: iwpriv athx conf_bssid 11:03:7F:46:03:17

Currently bool is used to check if scan node is active or not, and
if it is active the deletion can happen. Now if two thread tries to
delete the same node at same time, the first one to get the node
will delete the node and set the active bool to false. If the
delete operation leads to node being freed, the 2nd thread when gets
the lock tries to check the bool, if node is active and then return
if node is not active.
Now if before the 2nd thread check the bool, the memory is reallocate
and the byte pointing to the bool is overwritten with non-zero value
the 2nd thread will assume that node is still active and try to delete
and access an already freed node.
To fix this use cookie instead of bool to check if scan node is active.

For 4.9GHz, firmware converts the frequency to old regulatory channel
numbers and sends it to host. But host uses new regulatory channel numbers.
Since the received fw channel and beacon channel number is different,
host drops the received beacon and scan entry doesnot get updated.
As a temporary fix, bypass the beacon mismatch check in host.

Send correct channel list to Firmware. When cfg80211 is enabled, STA
is scanning in a set of wrong channels. When scan callback happens
from cfg80211 module the cfg80211 module gives us the channel numbers.
There are some channel numbers which are same in both 5GHz and in
2.4Ghz bands. For example, channel number 1 maps to frequency 4942MHz
in 5GHz band, but in 2.4GHz band channel number 1 maps to frequency
2412MHz. So cfg80211 may give us a wrong channel number. Since we have
the exact frequency of the channel we should use that instead of the
one given by cfg80211.
The channel object given to the driver by cfg80211 during scan callback
is the same as the one registered to cfg80211 by the driver. So we can
use the channel frequency inside the channel object for scan which is
not changed by the cfg80211 module.
Use regdb function to convert channel number to frequency while receiving
scan entries from FW. Use pdev band (5/2.4GHz) information to map to
correct 2.4Ghz/5Ghz channel frequency.
Half/Quarter rate flags in the scan_ctrl_flags are not set. Set
Half/Quarter rate flags in scan_ctrl_flags.

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

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
