Description Mark Murray 1994-12-26 10:00:01 UTC 
When the ethernet card is in NE2000 or 200tx mode, making TCP/IP
connections is very difficult. Pings work normally, but rsh is
badly slow, and eventually fades out, and telnet does not do
anything after the "connected to..." message. FTP seems to work OK.

I get random panics, and by taking down the address of the error, I
have found the following. 1) the error is "page fault in kernel mode"
2) The error seems to be occurring in ed_pio_write_mbufs() from if_ed.c.
(I got this by 'nm kernel | sort | less' and looking for the first
symbol before the panic address.

Fix: 

The card seems to work OK now in wd8013<> mode.
How-To-Repeat: 
Run my kernel with my ethernet card in ne2000/200tx mode.

Mark: 
These are both mine. Please close them, they have to do with the famous 
ne2000/if_ed failure, which is now fixed (not by me).
