2.1.115 fails to find DEC Tulip card (and TCP still chokes

Hello, all.

Having changed from 2.1.113 to 2.1.115-ac1, the kernel now fails to
recognise a DEC Tulip DC21041 PCI ethernet card.

It's there in /proc/pci, but no longer appears in the boot-up
messages after "PPP line discipline registered". In
drivers/net/tulip.c, the probe_tulip routine is called, but seems
not to recognise anything (tulip_debug settings have been tried, and
absolutely no output results).

Back to 2.1.113 for me.

Still having another problem (back at 2.1.113): large bursts of TCP
data leaving the machine on the PPP interface to the ISDN line cause
the TCP code to choke in both directions. Uploading large files to
my website brings the machine to a halt. Unloading and restarting
ipppd does not work; re-booting does.

Incidentally, when sending out large files, the ftp program reports
that around 62k of data leaves the machine immediately ... then all
TCP grinds down to around 20 bytes per second. Everything else is
working fine.

Thanks, again, to all who are, and have been, developing the system.
