Linksys Lite-On and 0.90q: much improved!

Hi all,

things have much improved, I'm glad to see, with the latest tulip driver
0.90q.  Where before I was seeing throughput in the area of .22 Mb/s, I now
see from 10-16 Mb/s, a huge boost.  Not great, but much, much better.

>From what I can see, it has everything to do with the CSR0 setting, but
I've not yet played around to find the optimal setting.  All I know is that
under the old setting (0x00A04800), I was getting *tons* of frame overflow
messages:

  eth0: Oversized Ethernet frame spanned multiple buffers, status 7fff8301!

but now I'm seeing far fewer with csr0=0x01A08000.  Still some, and hence,
it would seem, the less than optimal performance, but far fewer.  Thanks,
Donald!

Any further suggestions on how to get rid of the remaining frame buffer
messages?

Eric
