Module Name:	src
Committed By:	jonathan

Modified Files:
	src/sys/net: if_loop.c

Log Message:
Make if_loop MTU settable via SIOCSFMTU/ifconfig. Useful for testing,
and for regression-testing performance at various MTUs.

NB: route MTU may not track MTU changes, which may cause problems for
AF_ISO if loopback MTU is decreased. I've never seen problems with IP,
in various tests going back to around NetBSD 1.3.
