Knowing that the `vx' driver in -current is supposed to be quite
better operational than it used to be, i just tried to swap my
Ethernet cards on the fly (on a totally non-busy) network. 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. Still
nogo:

Never trust an operating system you don't have sources for. ;-)
