mwifiex: add firmware dump feature for SDIO
Firmware dump feature is added for SDIO based chipsets
which can be used with the help of ethtool commands.
1) Trigger firmware dump operation:
ethtool --set-dump mlan0 0xff
When the operation is completed, udev event will be sent to
trigger external application.
2) Following udev rule can be used to get the data from ethtool:
DRIVER=="mwifiex_sdio", ACTION=="change", RUN+="/sbin/mwifiex_sdio_fw_dump.sh"
mwifiex_sdio_fw_dump.sh: #!/bin/bash
ethtool --set-dump mlan0 0
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/ITCM.log
ethtool --set-dump mlan0 1
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/DTCM.log
ethtool --set-dump mlan0 2
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/SQRAM.log
ethtool --set-dump mlan0 3
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/APU.log
ethtool --set-dump mlan0 4
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/CIU.log
ethtool --set-dump mlan0 5
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/ICU.log
ethtool --set-dump mlan0 6
ethtool --get-dump mlan0
ethtool --get-dump mlan0 data /tmp/MAC.log
