Reviewed-by: Mike Christie <michaelc@xxxxxxxxxxx> Note that you should not need this for the iscsi tools though. The iscsi tools in git already figure this out for all drivers if you compile with OFFLOAD_BOOT_SUPPORTED set. Basically, if the MAC address in the firmware ibft/iscsi_boot dirs/info is the same as one in the /sys/class/iscsi_host dir then it is offload. For broadcom when you enable hba mode it puts the offloaded MAC address in ibft. If hba mode is not enabled then the MAC is the normal networking card port's MAC (in this case iscsi tools will just do iscsi_tcp over bnx2x/bnx2). -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
