I was wondering why NAPI hasn't been ported on 8139too yet..


I think it would be a good idea. You can stuff a lot of 68-byte packets into a 32K or 64K contiguous buffer. Jes Sorensen wrote a patch a while ago that sampling the incoming rate, and backed off if the rate was too high -- basically a poor man's NAPI.

So, volunteers?  Just convert the RX path to NAPI, not all interrupt events.
