There are different types of broadcom chips on my hardware:

bge0: <Broadcom BCM5721 Gigabit Ethernet, ASIC rev. 0x4101>
mem 0xddef0000-0xddefffff irq 16 at device 0.0 on pci5
miibus0: <MII bus> on bge0
brgphy0: <BCM5750 10/100/1000baseTX PHY> on miibus0
brgphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 1000baseTX-FDX, auto
bge0: Ethernet address: 00:15:f2:cd:21:9a

I don't have any other type of broadcom NIC to test but all other
NICs, for example Intel works correctly.

p.s. MB: ASUSTeK P5M2 /2GBL
