#ip link show br-vlan.440 | grep mtu | awk {'print $2 " " $4 " " $5 " " $9'}
br-vlan.440@br-vlan: mtu 1500 brq33fecdff-b3

#ip link show tap346c55b7-97 | grep mtu | awk {'print $2 " " $4 " " $5 " " $9'}

Change physical MTU & Restart Agent:

# ip link set mtu 9000 dev br-vlan.440
# service neutron-linuxbridge-agent restart

#ip link show br-vlan.440 | grep mtu | awk {'print $2 " " $4 " " $5 " " $9'}
br-vlan.440@br-vlan: mtu 9000 brq33fecdff-b3

#ip link show tap346c55b7-97 | grep mtu | awk {'print $2 " " $4 " " $5 " " $9'}
