[tulip] DC21143 rev 65 - hopeless case?

[John Sutton]

Result!  I've upgraded to 0.92t and done the stuff on /proc/sys/vm/freepages
and I'm delighted to report a successful outcome - transferred a 300Mb file
from Windoze to the server via samba.  During the transer I got one kernel
message:

Mar  8 09:29:00 diva kernel: eth0: Too much work during an interrupt, csr5=0xf0670040.

but a sum on the file at each end reports the same result, so I'm happy to
believe that it worked.

After 2 years of thrashing about in the dark with this problem, here is one
very happy hacker ;-)

Many thanks
John
