Problem Description:
The e1000e driver doesn't strip the ethernet frame crc is used with the
82566DM-2 chip.
This will result, among other things, that bridging doesn't work together with
this chip.
Reverting commit 140a74802894e9db57e5cd77ccff77e590ece5f3 fixes this issue but
has performance implications.

Steps to reproduce:
Send a ping and monitor the responce with tcpdump.
