From: "Michael Chan" <mchan@broadcom.com> Date: Fri, 2 Aug 2013 11:28:23 -0700 > On some bnx2x devices, iSCSI is determined to be unsupported only after > firmware is downloaded. We need to check max_iscsi_conn again after > NETDEV_UP and block iSCSI init operations. Without this fix, iscsiadm > can hang as the firmware will not respond to the iSCSI init message. > > Signed-off-by: Eddie Wai <eddie.wai@broadcom.com> > Signed-off-by: Michael Chan <mchan@broadcom.com> Applied, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
