Hi,
I've been fiddling with my laptop for a while now trying out different
drivers to try to get it to do full duplex to no avail.
I've tried various options to force it but none did anything at all and
using the mii-diag to force it doesn't work since it doesn't think it's
capable of doing FD for some reason I'm yet to understand.
Windows sees it fine and the extra lights on my switch light up
obligingly (and more importantly it transfers files faster :)) but with
the linux driver it doesn't seem to do it. This is with the driver in
2.4.17 and with Donald Becker's driver.
I did look at the source but it seems to totally trust the EEPROM and I
don't really know what I'm /meant/ to have in my EEPROM to say "Yes, I
can do FD, honest, guv".
Here's the vortex-diag and mii-diag output. Any ideas?
