This patch adds support for virtual LAN (VLAN) tagging. VLAN tagging allows multiple VLANs in a bridged network to share the same physical network link but maintain isolation: http://en.wikipedia.org/wiki/IEEE_802.1Q * grub-core/net/ethernet.c: Add check, get, and set vlan tag id. * grub-core/net/drivers/ieee1275/ofnet.c: Get vlan tag id from bootargs. * grub-core/net/arp.c: Add check. * grub-core/net/ip.c: Likewise. * include/grub/net/arp.h: Add vlantag attribute. * include/grub/net/ip.h: Likewise.
