Re: wpi (Intel 3945abg) Memory Allocation Errors on Receive > 0
"Allocation error on receive" could be due to a couple
of things in the wpip driver. This stat is actually
printing out ifp->if_ierrors (same count as 'netstat -in').
Try running just the wpi driver without the 'pagesize' and
'mclsize' args and check the sloginfo.
