Sorry, I assumed the problem was well known in NetBSD (given that Open and
Free are fixed.) In any case:
dive@jane:/home/dive % ifconfig sk0
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:11:d8:3a:76:87
        media: Ethernet autoselect (1000baseT full-duplex)
        status: active
        inet 192.168.1.7 netmask 0xffffff00 broadcast 192.168.1.255
dive@jane:/home/dive % sudo ifconfig sk0 mtu 4096
ifconfig: SIOCSIFMTU: Invalid argument

And... where can I find these patches?

The google, it does nothing.
