For the 57810 I have tracked this down to the status block in the VF failing to be updated. =C2=A0The linux driver works fine but it appears t= o use a slightly different scheme -- writing some sort of fastpath status block generation per interrupt. Does anyone have any suggestions or a programming guide for this device?
