Here is pciconf, ifconfig and dmesg output:

$ pciconf -lv | grep -A4 '^nfe0'
nfe0@pci0:10:0:	class=0x020000 card=0x82b31043 chip=0x054c10de rev=0xa2 
hdr=0x00
    vendor   = 'Nvidia Corp'
    device   = 'MCP67 Ethernet'
    class    = network
    subclass = ethernet

$ ifconfig nfe0
nfe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
	options=8<VLAN_MTU>
	ether 4f:ad:6d:c6:1f:00

$ dmesg | grep nfe0
