Intel Pro100+(82559) Polling Driver Problems

[Brecht Vermeulen]

Hi Pramod,

mmm, that's strange, I cannot find the Linux patch for 2.2.20 in current
CVS. How have you patched your kernel for this ?

Or are you using userlevel mode ? 

I think polling doesn't work in userlevel mode. (but I don't know how it
comes that your configuration works then)

regards,
Brecht
