ifconfig reports an enormous amount of errors

[GTVincent]

I'm noticing an enormous amount of RX errors when requesting the network status using ifconfig:

ath0 Link encap:Ethernet HWaddr 00:11:95:91:C1:6C

The amount of errors goes up with 5 per second or so. The network adapter is a D-Link using an Atheros chip:

I used to have this card in a 32 bit AMD machine using ndiswrapper, where it just got unmanagable because ndiswrapper would report the resetting of eth0 all the time, so I bought a new card for that machine. Now it's in an amd64 machine, using the madwifi drivers since ndiswrapper won't be able to use the 32 bit windows drivers that came with the card.

Question is: what causes all these errors? Is this card (about to be) broken? Or is there something in the madwifi drivers that could fix the errors?
