>Description:
I have motherboard with integrated 3Com ethernet controller, listed
from pciconf output as:

xl0@pci2:8:0:   class=0x020000 card=0xffffffff chip=0x920210b7 rev=0x40 hdr=0x00
vendor   = '3COM Corp, Networking Division'
device   = '3C920B-EMB-WNM Integrated Fast Ethernet Controller'
class    = network
subclass = ethernet

but current xl(4) driver does not have support for this controller.
Very trivial patch adds support for him, and this controller seems working OK
(tested with heavy NFS traffic):

xl0: <3Com 3c920B-EMB-WNM Integrated Fast Etherlink XL> port 0xec00-0xec7f mem 0xfe100000-0xfe10007f irq 3 at device 8.0 on pci2
miibus1: <MII bus> on xl0
xl0: Ethernet address: 00:11:2f:44:6f:87

xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=9<RXCSUM,VLAN_MTU>
	inet 10.20.30.211 netmask 0xffffff00 broadcast 10.20.30.255
	ether 00:11:2f:44:6f:87
	media: Ethernet autoselect (100baseTX)
	status: active
	
And supports at least autonegotiation without any problems.
