While sending null packet from driver we are passing NULL
tx_param pointer to indicate there are no more packets in queue.
PCIe send routine assumes caller has done sanity check on
tx_param and may cause crash while dereferencing next_pkt_len
from tx_param.
Avoid this by passing tx_param structure with next_pkt_len as
zero instead of NULL pointer.

During SDIO MP aggregation, we at first acquire current write
port to write data onto and then proceed with using this port
for SDIO write. If error occurs later in mwifiex_write_data_sync
because device is suspended or SDIO write failure, we do not
restore current write port and write bitmap. This results into
leaking one port and hole in SDIO write port bitmap.
Restore current write port and reset bitmap accordingly in
failure cases to avoid this.

These devices require commands stored in buffers in an odd order,
different from that in which the CRC is computed.
Rather than make two copies of the commands in two different orders,
form the commands in logical (CRC) order, append the CRC, then byte-swap
in place to the desired order.
The old code worked fine, I'm just scratching an "ugh, that's ugly"
itch.

unnecessary. Make it possible to bypass the worker if fws mode

this configuration is set true to have fws provide queueing
regardless the fws mode.

When a BSS provides both 2.4GHz and 5GHz bands, in many cases it
makes sense to choose 5GHz. Typically a 5GHz channel is less crowded
and has less interference and therefore its performance will be
better than a crowded 2.4 GHz channel. This patch configures
'join_pref' to induce firmware to preferably select 5GHz BSS.
