Most cards offer Full-Duplex today. I think the reason more people use 2 cards nowadays is for assigning multiple IPs to their box.

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... (3 Replies)

TXP(4) BSD Kernel Interfaces Manual TXP(4)
NAME
txp -- 3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device txp
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_txp_load="YES"
DESCRIPTION
The txp interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the 3Com Typhoon/Sidewinder chipset.
Basic Ethernet functions are provided as well as support for vlan(4) tag removal and insertion assistance, receive ip(4), tcp(4), and udp(4)
checksum offloading, and transmit ip(4) checksum offloading. There is currently no support for transmit tcp(4) or udp(4) checksum offload-
ing, tcp(4) segmentation, nor ipsec(4) acceleration.
Each of the host's network addresses is specified at boot time with an SIOCSIFADDR ioctl(2). The txp interface employs the address resolu-
tion protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network.
When a txp interface is brought up, by default, it will attempt to auto-negotiate the link speed and duplex mode. The speeds, in order of
attempt, are: 100Mb/s Full Duplex, 100Mb/s Half Duplex, 10 Mb/s Full Duplex, and 10 Mb/s Half Duplex.
The txp supports several media types, which are selected via the ifconfig(8) command. The supported media types are:
media autoselect
Attempt to autoselect the media type (default)
media 100baseTX mediaopt full-duplex
Use 100baseTX, full duplex
media 100baseTX [mediaopt half-duplex]
Use 100baseTX, half duplex
media 10baseT mediaopt full-duplex
Use 10baseT, full duplex
media 10baseT [mediaopt half-duplex]
Use 10baseT, half duplex
HARDWARE
The txp driver supports the following cards:
o 3Com 3CR990-TX-95
o 3Com 3CR990-TX-97
o 3Com 3cR990B-TXM
o 3Com 3CR990SVR95
o 3Com 3CR990SVR97
o 3Com 3cR990B-SRV
SEE ALSO
altq(4), arp(4), inet(4), intro(4), ip(4), miibus(4), tcp(4), udp(4), vlan(4), ifconfig(8)
HISTORY
The txp driver first appeared in OpenBSD 2.9.
