I think the point is that FCoE wants to use OPTIMAL_FCOEMTU (2KB + a bit for headers) even when netdev->mtu is 1500. (eg datacenter network supports baby jumbo frames so FCoE traffic that stays within the network should use OPTIMAL_FCOEMTU, while lots of IP traffic is going out onto a 1500-byte MTU campus and having TCP doing lots of PMTU discovery is a pain) - R. -- 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
