ovs: set MTU from connection when creating an internal interface
The ovs-vswitchd.conf.db(5) man page says about the the mtu_request
column in the Interface table:
"Requested MTU (Maximum Transmission Unit) for the interface. A
client can fill this column to change the MTU of an
interface [...] If this is not set and if the interface has
internal type, Open vSwitch will change the MTU to match the
minimum of the other interfaces in the bridge."
Therefore, if the connection specifies a MTU, set it early when adding
the interface to the ovsdb so that it will not be changed to the
minimum of other interfaces.
