Re: [Fwd: problem with dual 3com card]

i forced the switch into full_duplex and tried to force the card, too
(via full_duplex=1,1)
its clear that the combination autoneg + force does not work, but why 

my experiences here:

switch	card	result
----------------------
auto	auto	works
auto	force	does not work (but this is ok)
force	auto	does not work (but this is ok)
force	force	does not work (imho not ok)

if i try force+force i loose the link as mentioned by mii-diag:
Basic registers of MII PHY #24:  3000 7809 0040 6177 0541 0000 0000
0000.
 Basic mode control register 0x3000: Auto-negotiation enabled.
 Basic mode status register 0x7809 ... 7809.
   Link status: not established.

and i see "Auto-negotiation enabled.", which should not be true.
or am i missing something?
does forcing mean, that i still have autoneg, but with less available
options?
and how would i force card into 100FD, just by using module parameters?
0x204 is only valid for 3c595, but not for my 3c982.
