Hey, Keith,
I may have missed your answer to this - have you tried tcpdump while trying to send, once it looks good? Does ethtool ever think there's a link?
I'm the OP, and no I haven't done a capture yet. Not a bad idea, thanks! Ethtool does indeed report a link, and it shows the proper modes for the interface (10mbit full/half duplex and 100mbit full/half duplex).
