cperciva 3a3c030ccd Skip setting the MTU in the netfront driver (xn# devices) if the new MTU ... is the same as the old MTU. In particular, on Amazon EC2 "T2" instances without this change, the network interface is reinitialized every 30 minutes due to the MTU being (re)set when a new DHCP lease is obtained, causing packets to be dropped, along with annoying syslog messages about the link state changing. As a side note, the behaviour this commit fixes was responsible for exposing the locking problems fixed via r318523 and r318631. Maintainers of other network interface drivers may wish to consider making the corresponding change; the handling of SIOCSIFMTU does not seem to exhibit a great deal of consistency between drivers.
