[SCSI] be2iscsi: Add support for iscsi boot
This patch contains changes for adding support for iscsi_boot. Have modified to make read of mac address from chip as a function. The mac_address is being cached after teh first call as it is not expected to change Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: Jayamohan Kallickal <jayamohank@serverengines.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
