tools/hotplug: set mtu from bridge for tap interface
With changeset 22885 support was added for setting the MTU in the vif-bridge
script for when a vif interface was set to 'online'. The was not done for the
'add' operation. The 'add' operation was added to the script for when tap
devices were specified (c/s 21944). With the setting of the MTU for the
'online' case was there a reason for omitting the 'add'?
This patch sets the MTU for both 'online' and 'add' in the vif-bridge script.
