This patch contains the iproute changes needed for VLAN configuration.
Examples:
Add VLAN device:
# ip link add dev eth0.1000 link eth0 type vlan \
id 1000 \
egress-qos-map 1:2 2:3 \
ingress-qos-map 2:1 3:2
Show new device:
# ip link list eth0.1000
9: [EMAIL PROTECTED]: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
link/ether 8e:bb:6f:05:29:e9 brd ff:ff:ff:ff:ff:ff
vlan id 1000
ingress-qos-map { 2:1 3:2 }
egress-qos-map { 1:2 2:3 }
Delete device:
# ip link delete eth0.1000
[IPROUTE]: VLAN support
