Hi, it's me again.

I've been seeing this "ae0: ring buffer overrun" error very often when
I send a chunk of data from my notebook PC running FreeBSD (*gasp*) to
my SE/30 running NetBSD, resulting in transfer rates ranging from
30KB/s to 80KB/s.  The other way is much faster, ranging from 150KB/s to
300KB/s (still slow, I know).

The Ethernet card in the unaccelerated SE/30 is a Kinetics EtherPort
SE/30 which is currently unsupported officially.  However, I've
patched if_aereg.h and if_ae.c to get it to work.  Basically, the
EtherPort SE/30 is an ordinary NIC based card that has a byte-wide
shared buffer rather than a more popular word-wide buffer, so the
changes I've made are only to the initialization sequence.

Has anybody seen this, too?  Or am I the only one?

BTW, the rights to EtherPort is now sold to Dayna, but their newer
DaynaPORT E/30s are much different creatures (SONIC based), so it
might take a while to support them.  Yet, the stock ae driver
identifies them as a same card which could prevent my changes to the
driver from working.  I need to know how to distinguish the two cards
before I can submit the changes to Scott.  If anyone with a DaynaPORT
card could run Slots (a MacOS app written by Apple), write down its
output on the Ethernet card, and send it to me, I'd greatly appreciate
it.
