I have similar experience, just tried to change it, but didn't notice
any big difference. I have not done detailed measurements on this
however with every burst size possible.

We have a setup where we use some mediaconvertors to convert it to
single mode fibre and with some 12 km fibre in between and there I can
see a low number of Rx CRC errors in
/proc/net/PRO_LAN_Adapters/eth?.info, so I guess these numbers come from
the card itself which would mean that the card itself does CRC error
checking.
