Sorry to follow up my own post, but...
More specifically, it appears the packet does
try and transmit, but the destination MAC is
(uninitialised?) somewhat random, different
on each packet, not legal.

I can capture it on the correct output interface
with tcpdump. The interface type is xl.

Shouldn't the stack ARP for the destination
in my 'sendto', and fill in the ether header?
The ether-source is filled in, presumably by
the driver.
