Indeed - no problem with -p. (So now, why can dhclient cope with promiscous
mode?)

Just checked again:

  dhcpd msk0
  tcpdump with -p, all OK.
  tcpdump without -p, no good.
  dhcpcd -k msk0
  dhclient msk0
  tcpdump without -p, all OK (ifconfig shows PROMISC set)

Now back to why nfs clients seem to get stuck in nfsrcv...
