Check /proc/net/dev for better stats.
Hmmm, that's a very low collision number.  Verify that you haven't forced
full duplex somehow.  That would explain Rx errors.

Or perhaps some other host is set to full duplex.  The usually, but not
always, results in Tx errors rather than only Rx errors.

Note: you only need to shroud your Ethernet address when you have
Wake-On-LAN boards :-O.
