Warning: this freezed the system immediately [all network connectivity
broke, and I had to do a quick reset].  Maybe I should have set it up
at reboot before the system was in a 'bad' shape..

Speaking of 6to4, if_stf.c does not support setting the MTU, because
there's no ioctl handler for it.  It wouldn't IMHO hurt to be able to
raise it from the glued-in default of 1280..
