I've ifconfig delete'd the ed0 interface, and ifconfig'ed vx0. Seems i forgot to clear the old ARP entries, since when i tried to diskless boot my scratchbox (which used to stall immediately with the old vx driver), now i've got: Dec 19 21:32:28 uriah bootpd[1227]: set: can only proxy for 192.168.0.3 Dec 19 21:32:29 uriah bootpd[1227]: set: can only proxy for 192.168.0.3 Dec 19 21:32:29 uriah /kernel: arpresolve: can't allocate llinfo for 192.16 8.0.3 Dec 19 21:32:29 uriah /kernel: arpresolve: can't allocate llinfo for 192.16 8.0.3 Hmpf. Ok, revert everything to state 0, delete all ARP entries and other routes, delete all interfaces, and try to start over.
