Subject: [PATCH] mwifiex: device dump support via devcoredump framework

Currently device dump generated in the driver is retrieved
using ethtool set/get dump commands. We will get rid of
ethtool approach and use devcoredump framework.

Device dump can be trigger by
cat /debugfs/mwifiex/mlanX/device_dump
and when the dump operation is completed, data can be read by
cat /sys/class/devcoredump/devcdX/data

We have prepared following script to split device dump data
into multiple files.

 [root]# cat mwifiex_split_dump_data.sh
 #!/bin/bash
 # usage: ./mwifiex_split_dump_data.sh dump_data

 fw_dump_data=$1

 mem_type="driverinfo ITCM DTCM SQRAM APU CIU ICU MAC"

 for name in ${mem_type[@]}
 do
     sed -n "/Start dump $name/,/End dump/p" $fw_dump_data  > tmp.$name.log
     if [ ! -s tmp.$name.log ]
     then
         rm -rf tmp.$name.log
     else
         #Remove the describle info "Start dump" and "End dump"
         sed '1d' tmp.$name.log | sed '$d' > /data/$name.log
         if [ -s /data/$name.log ]
         then
             echo "generate /data/$name.log"
         else
             sed '1d' tmp.$name.log | sed '$d' > /var/$name.log
             echo "generate /var/$name.log"
         fi
         rm -rf tmp.$name.log
     fi
 done
