Subject:   lousy ethernet performance w/21143
Message-ID:  <199906071925.NAA23913@panzer.plutotech.com>

I'm not sure whether this is specifically an Alpha issue, or whether it
affects -current or the de driver in general.

But, on my 433au box here, I'm getting really lousy network performance
with -current from Saturday.  Performance was fine with a kernel from
around April 23rd.  In fact, I can still boot that kernel and the network
performance is fine.  (so it probably isn't hardware or cabling)

The machine is on a half-duplex 100BaseT network (i.e. none of the full
duplex problems with the de driver and the 21143).

With the old kernel, from late April, I can get 7-8MB/sec throughput using
tcpblast to a machine on the local network.  With the new kernel, from
Saturday, I'm only getting about 6-7 Kilobytes/sec.

This part is interesting:

Every outgoing packet seems to generate an error!  Full dmesg output from
the machine is below.

Anyone have any ideas about what the problem could be?

Oh, one other thing.  There are two differences in the kernel configuration
from April 23rd and the current configuration:  I added the fd driver and
the ATAPI stuff.
