[realtek] RealTek 8139 -- problem forcing 10baseT

[=?iso-8859-1?Q?Ingar_=D8yahals?=]

Hi,

I'm having problems using my RealTek 8139-baced NIC with a 10baseT-based
switch.

The situation is this:

Catalyst 1900 10mbps-FD <-------------> rtl8139

The catalyst switch does not support autonegotiate and is constant 10 mbps
full duplex.
I'm running linux slack 2.2.16-kernel using v-1.13 of the rtl-driver.
I've compiled 'mii-diag' with both 'libmii' and 'libflash'

Problem is, that I can't force 10baseT using mii-diag;

--
root@cs:~/src/driver/diag# ./mii-diag -F 10baseT eth0
Setting the speed to "fixed", Control register 0100.
SIOCSMIIREG on eth0 failed: Operation not permitted
Basic registers of MII PHY #32:  1000 782d 0000 0000 05e1 0000 0000 0000.
 Basic mode control register 0x1000: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner does not do autonegotiation, and this transceiver type
  does not report the sensed link speed.
--
I load the module using 'insmod rtl8129 full_duplex=1' to force full duplex
since I can't do that either using 'mii-diag'
I'm running 'mii-diag' as root so the permissions should be sufficient.
I'm getting a lot of collisions and errors because the speed initially is
set to 100mbps.

One final question; how do I determine the speed the NIC is operating at?
Anyone out there who could help me?
