From 7d64abbc5d0b5dfe4810883f372b905a359f2697 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Fri, 1 Mar 2013 16:32:16 +0100 Subject: [iscsi] Include 802.1Q VLAN identifier in iBFT The iBFT NIC section has a VLAN field which must be filled in so that iSCSI booting works over VLANs. Unfortunately it is unclear from the IBM specification linked in ibft.c whether the VLAN field is just the 802.1Q VLAN Identifier or the full 802.1Q TCI. For now just fill in the VID, the Priority Code Point and Drop Eligible Indicator could be set in the future if it turns out they should be present too.
