James Dingwall 7d6c3308cb tools/hotplug: validate mtu read from xenstore against RFC 791 minimum 
RFC 791 sets the minimum acceptable mtu to 68:

    Every internet module must be able to forward a datagram of 68
    octets without further fragmentation.  This is because an internet
    header may be up to 60 octets, and the minimum fragment is 8 octets.

In the Linux kernel source:

include/net/ip.h:#define IPV4_MIN_MTU           68              /* RFC 791 */

While there is no reason to expect a value <68 to be read from xenstore or
from the bridge make the value test require a number >= this minimum.
