cnic, bnx2: Check iSCSI support early in bnx2_init_one()
Based on earlier patch from Neil Horman <nhorman@tuxdriver.com> If iSCSI is not supported on a bnx2 device, bnx2_cnic_probe() will return NULL and the cnic device will not be visible to bnx2i. This will prevent bnx2i from registering and then unregistering during cnic_start() and cause the warning message: bnx2 0003:01:00.1: eth1: Failed waiting for ULP up call to complete Signed-off-by: Michael Chan <mchan@broadcom.com> Cc: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
