Problems switching to Full Duplex

We run Compaq UNIX Tru64 5.1.

After a switch got replaced our ethernet-card was magically set to
half duplex!

We saw, that the card was set to Autonegotiate:
vmunix: ee1: Autonegotiated, 100 Mbps full duplex

So we set the card with ifconfig to 100 Mbps full duplex with the
following commands:

ifconfig ee1 down speed 200
ifconfig ee1 up

We received the following confirmation:
vmunix: ee1: Autonegotiated, 100 Mbps full duplex
vmunix: ee1: Autonegotiated, 100 Mbps full duplex


It was fine until the next reboot. The card was again set to half
duplex. So we tried also the following command in the console mode:

set EWA0_MODE FastFD

It doesn't change anything.

How can we hard set ethernet card-mode to full-duplex?

Thanks for answers.

NAME
xirc2ps_cs - Xircom CE2ps (and newer) device driver SYNOPSIS
insmod xirc2ps_cs.o [pc_debug=n] [full_duplex=n] [irq_list=i,j,...] [if_port=n] [lockup_hack=n] DESCRIPTION
xirc2ps_cs is the low-level Card Services driver for the Xircom 16-bit PCMCIA ethernet adapters. When this driver is attached to a card, it allocates the next available ethernet device. PARAMETERS
pc_debug=n Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero value enables debugging. if_port=n Selects the transceiver type, for some CE3B-100 cards that lack the ability to autonegotiate. For such cards, a value of 1 selects 10baseT, and 4 selects 100baseT. full_duplex=n Selects full duplex mode. The default is 0 (half duplex). irq_list=i,j,... Specifies the set of interrupts that may be allocated by this driver. lockup_hack=n Enables a hack to avoid lockups on some cards. Use this only if you really have lockup problems with your card.
