I have a wm0 that shows up like this:

wm0 at pci1 dev 2 function 0: Intel i82543GC 1000BASE-T Ethernet, rev. 2
wm0: interrupting at ioapic1 pin 5 (irq 7)
wm0: 64-bit 33MHz PCI bus
wm0: 64 word (6 address bits) MicroWire EEPROM
wm0: Ethernet address 00:03:47:25:42:14
makphy0 at wm0 phy 1: Marvell 88E1000 Gigabit PHY, rev. 2
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto

It is connected to a GigE switch, and it works fine in 100baseTX mode.
But in default (1000baseT full-duplex) mode (nor in 1000baseT mode) it does
not seem to be able to send or receive any packets.

ifconfig wm0 says:

wm0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
	address: 00:03:47:25:42:14
	media: Ethernet autoselect (1000baseT full-duplex)
	status: active

(no IP added here, but for the tests I did that, of course)

Not sure what makes this hardware special.
