em0 at pci0:0:31:6:	class=0x020000 card=0x07a11028 chip=0x15e38086 rev=0x00 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Ethernet Connection (5) I219-LM'
    class      = network
    subclass   = ethernet
    bar   [10] = type Memory, range 32, base 0xf7100000, size 131072, enabled
    cap 01[c8] = powerspec 3  supports D0 D3  current D0
    cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message
    cap 13[e0] = PCI Advanced Features: FLR TP
