The second reset is not generated by the Linux TCP/IP stack (we never send
RSTs with options and windows). It looks like a normal ACK with a few bits
flipped (?). 

The first one is bogus too because it has wrong sequence numbers, but at least
the rest of the header looks normal. 

I would check the ethernet driver/card.
