Re: Wallstreet Ethernet

I was wondering if any progress has been made on the Wallstreet /
ethernet problems issue that was being discussed a while back?

I haven't seen anybody working on this. After the initial  discussion
(especially  with Benjamin Herrenschmidt) it seems clear that this is
a know problem which can cause Tx packets to become corrupted.

I'm seeing the same issues - real slow connections, a shedload
of packet collisions and occasional crashes when the disk is
grinding.

... and probably corrupted data on outgoing connections.

I can probably gather some more stats if that would be helpful.

Thanks, but this is probably not necessary - the problem seems clear.

I'd have a go at hacking the code if I had the time, but I'm working
18+ hour days at the moment.  Such is life <sigh>.

Same for me - I don't know enough about the BMAC hardware, and  don't
have time to learn it right now.

I sent a message asking for help to Benjamin Herrenschmidt  and  Paul
Mackerras (on Monday, April 17), but got no reply yet :-(
