I heard that some one has written an ethernet driver for the IBM PPC 405
board for Linux some time ago. The author has seen performance
improvement because the driver services interrupts in a better way. If
some one has a copy of the driver, would you please send it to
binh@us.ibm.com. Also any tips on how to install the driver is
appreciated. Thanks very much.

The driver is included in the linuxppc_2_4_devel and linuxppc-2.4
kernel trees. You probably want to be using one of those trees in any
case.

He might be referring to a post here (in the last 6 months or so)
where the poster mentioned writing a replacement EMAC driver that
had better performance than the standard driver. I can't seem to
locate the post at the moment, but perhaps somebody else remembers
and can find it in the archives.

Was it this one:
"RE: Network performance loss when migrating to 2.4.18 on Walnut 4 05GP"
http://lists.linuxppc.org/linuxppc-embedded/200303/msg00079.html
I tried the patch mentioned (against MontaVista 2.1) and found a few %
improvement, not as much as I was hoping.

Some clarifications to the origional posting: I am refering to a post
where the poster mentioned writing a replacement EMAC driver that had
produced better performance than the standard one shippped with MontaVista
Linux.
