GMAC ethernet

GMAC ethernet

[GIANT Network Productions]

What's the current status of the GMAC ethernet driver? I've been
looking to do several things with an iBook that require interface
aliases and multicast, but those features aren't currently supported.
I've been pulling linux-pmac-benh from linuxcare.com.au, but Paul
mentions that Ben's changes have been merged into linux-pmac-stable
on his new status page and Ben states that he's working on
'experimental' stuff only...

I'm less concerned with video performance (which seems to be where
Paul is focusing at the moment) than with networking features - Which
tree should I be pulling to keep better tabs on this issue?

We could probably allow multicast by enabling the controller's promisc.
mode and let the kernel filter out packets. Not the most efficient thing
but at least it would work until we have some details about the chip's
hash table layout. I'll look into this, but my iBook's hard disk is dead,
I'm still waiting for a replacement.

Stick to Paul's tree. atyfb doesn't work on the iBook rage mobility yet,
but offb along with accelerated X server works for now. I'll do some work
on atyfb real soon (probably this week-end) to fix other problems, I'll
also try to fix it on the iBook. XServer acceleration already works (at
least with Xpmac).
