Hi Tim, All,

Isn't it always the way ? Downloaded the new version of the natsemi
NS83815.pdf file (dated Sep 2002), and the message about the 83815 (used
on the Netgear Fa311 / Fa312 cards) not supporting ethernet pause frames
has disappeared.

Looks like a bug in the old doco rather than the hardware.

Here is the updated patch, with the check for the NS83816 chip removed.

It applies to natsemi.c version 1.0.17, which is contained in both
versions 2.4.20 and 2.5.56 of the linux kernel.

I'm hoping other people can help me test it, I'd appreciate bug reports,
suggestions and other constructive criticism.

I've put the patch here

just in case attaching it to my last email was a bit rude (I didn't
think a 5 KB email was too big, my appologies if it was).
