Vortex full-duplex doesn't work?

Vortex full-duplex doesn't work?

[Karel Kulhavý]

Hello

I have collected from tidbits of information that
ether=0,0,0x201,0,eth0 should set my 3c900 card to full duplex AUI.

I have tried this, then ifconfig eth0 up and then
vortex-diag -vv and it still reports MAC Settings: half-duplex

When I rewrite all occurences of full_duplex in 3c59x.c for hard-coded
"1", then I get MAC Settings: full-duplex

How do I set up this driver to force full-duplex AUI for 3c900 network
card without using modules and without patching 3c59x.c?

BTW, what kernel version ???

As I indicated in another reply to you, <quote>
Please try this, although I'm not yet convinced that the 3c59x
driver calls all of the right hooks for this to work.
but good luck, and please report back on it. </quote>

It looks to me like (but I haven't traced it completely)
3c59x doesn't call netdev_boot_setup_check() [even indirectly],
and that is needed to set the irq/base/mem_start/mem_end
parameters for use during the probe() function.
(I'm looking at 2.4.22 source code for this.)
(3c59x uses mem_start for driver options flags.)

Can anyone confirm this?  If so, we could fix it, but I'd
like to have some confirmation of what I'm thinking on this
since I can't test it (no vortex/boomerang adapter).

2.4.22

So the only possibility apart from introducing modules is hacking it up in the
driver? I tried the 3Com setup DOS diskette and it refuses to set full duplex
together with AUI.

Yes, I believe so.

That makes sense.  Fdx requires 2 copper wire pairs.  AUI is a shared
wire medium.

OK, AUI is a 15-pin (?) connector, not a cable at all.
Are you using a twisted-pair MAU on the AUI connector, or are you
using a single ethernet cable?
(I don't know enough about the driver for this to matter.)
