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.home | help
