We set scan channel gap TLV to FW in scan command when any of the

Also when scan channel gap is enabled, we would scan maximum channels

This was happening because driver sets passive scan type only

When aggregation port limit is reached, we stop aggregation and
the data is sent to firmware. It is observed that one less packet
than the port limit is aggregated in this case. ex. 15 instead of
16.
The reason is we have redundant port limit checks before current
packet is added to aggregation buffer.
The issue is fixed by removing these checks. We already have

When assocaiting to an AP , mwifiex set supported data rates
based on target AP's capability. For 5G AP(11a mode), a/n/ac mode
would possibly be set.
However, for some chips which dont support 11AC mode current config_bands
will be used instead.
For example, if we join an IBSS in 11b mode ,adapter->config_bands
will be set to 1(11b mode). Then we leave IBSS ,and try to connect
5G a/n mode AP. At this time , only 11b mode data rates will be
supported in assoc request , which result in assoc failure with
reason code 18: Association denied due to requesting station not
supporting all rates.
This patch fix such a cornel case, by adding additional check for
current chip's 11ac capability.

This would cause association failure if AP is not found in first scan

scan commands from scan pending queue and command pending queue are
sent to FW and response to last scan command is received.

The Bluetooth core already does processing of the HCI command header
and puts it together before sending it to the driver. It is not really
efficient for the driver to look at the HCI command header again in
case it has to make certain decisions about certain commands. To make

information. The extra information about the opcode is optional and
