[sos-devel] [PATCH v2] sosreport: Capture IBM Power RAID storage adapter configuration information

[Aruna Balakrishnaiah]

Capture information which helps in better understanding of
IBM Power RAID storage adapter configuration. Since iprconfig
is specific to power adding the relevant commands in powerpc plugin.

Signed-off-by: Aruna Balakrishnaiah <aruna at linux.vnet.ibm.com>
---
Since lsscsi lists all types of enclosures and we are interested just in
IBM Power RAID enclosures have relyed on iprconfig results. /sys or /proc
does not give enough information to determine if its a RAID enclosure or not.

Changes from v1:
	Move this to a separate plugin
        Use call_ext_prog
        Use iprconfig results to parse
