1053 the user can write a 1 (enable) or 0 (disable) to 'fwlog/enable'. An example
1056   # echo 1 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/enable
1060 The FW log data can be retrieved by reading from 'fwlog/data'. The user can
1061 write any value to 'fwlog/data' to clear the data. The data can only be cleared
1067   # cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data > fwlog.bin
1071   # echo 0 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data
1077 'fwlog/nr_messages'. The range is 1-128 (1 means push every log message, 128
1080 'fwlog/nr_messages'. An example to set the value is::
1082   # echo 50 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/nr_messages
1089 To change the amount of memory then write to 'fwlog/log_size'. The value must be
