I'm confused. As I said in previous mail please check network cables
such that down-shifting wouldn't take part in this issue. If that
does not fix the issue, force speed/duplex on both ends.

Bad checksum seems to be different issue to me. Capture traffic on
Mac with tcpdump and give me a URL for the pcap file.
Btw, it would be even better if you can show me the PHY driver
(e1000phy(4)) information in dmesg output.
