Avinash Patil 8d767dcbea mwifiex: set valid tx_param during mwifiex_send_null_packet
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.

Avinash Patil bb71d01a42 mwifiex: restore current SDIO write port in failure cases
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.

George Spelvin e757201b8d drivers/net/wireless/ti/wl*/spi.c: Simplify CRC computation
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.

George Spelvin 1836eea209 lib/crc7: Shift crc7() output left 1 bit
This eliminates a 1-bit left shift in every single caller,
and makes the inner loop of the CRC computation more efficient.

Renamed crc7 to crc7_be (big-endian) since the interface changed.

Also purged #include <linux/crc7.h> from files that don't use it at all.

Johannes Berg af7c603eb4 iwlwifi: fix LED support Kconfig dependencies
If DVM or MVM are built-in but LEDS_CLASS isn't then the current
Kconfig will enable LED support and fail the build. Fix this by
making the LED support depend on LEDS_CLASS being built-in or,
if it is modular, only enabling it if iwlwifi also is.

Matt Chen 1504f48df4 iwlwifi: mvm: add uapsd_disable module parameter
Some APs (e.g. TP-LINK TL-WA801N) are disabling aggregation (downlink
to station) when U-APSD is enabled, resulting in low throughput.
Add a module parameter to allow disabling U-APSD support in the driver.

Also re-enable U-APSD for -9 firmware since the firmare issues were
fixed in this release.

There are devices that won't support U-APSD even with newer
firmware, so bring the TLV flag back to detect those.
