From: Hannes Reinecke <hare@xxxxxxx>
Some iSCSI initiator present firmware information in
/sys/firmware/ibft or /sys/firmware/iscsi_bootX
Whenever we detect one of those directories we should assume
that the iSCSI devices should be activated.
Also incorporates SUSE patches:
0049:
95iscsi: Use 'ip=ibft' for ibft autoconfiguration
For iBFT autoconfiguration we should be setting 'ip=ibft'
instead of rd.neednet. This should instruct dracut to only
enable the iBFT interfaces and leave the rest alone.
References: bnc#879038
0054:
95iscsi: update commandline printing
dracut has a separate callout 'cmdline' which should be used
for printing out the generated commandline.
