Subject: e1000 tcp checksum incorrect, x86 64b

App is writing seven bytes to the socket. Socket write timeout expires
and the seven bytes are sent. The checksum is not getting inserted
into the packet. It is set to a constant 0x8389 instead of the right
value.  App is gmpc 0.15.4.95, Revision: 6794

Attached Wireshark packet trace show the problem. e1000 is 192.168.1.4
64bit, Q6600. Dell Dimension 9200

Checksum is being computed ok for file copy traffic.
Problem was in rc7 too, I upgraded to current git to see if it was
fixed and it isn't

Wireshark is 0.99.4 from Ubuntu in case it is the problem.
