scsi: be2iscsi: Fix gateway APIs to support IPv4 & IPv6
Gateway APIs assume IP type as IPv4. Modify it to be generic to allow clearing of IPv6 gateway set using BIOS. Signed-off-by: Jitendra Bhivare <jitendra.bhivare@broadcom.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
