Version tested: DragonflyBSD 1.4 ReleaseSympthomes: dhclient can't receive DHCPOFFERS, becuse he does not send anything over the wire.
`tcpdump -n -i xl0 -vvv` shows, that bootp request packet was sent, but not xmit led
on netcard, not data led on cable modem are blinking. Confirmed with xl/rl/tl polling on and off.
