What you did here was "pciconf -lvcb | grep igb", or something
equivalent. There is output after each of these entries which is highly
relevant. Example for an emX device:
em1@pci0:15:0:0: class=0x020000 card=0x109a15d9 chip=0x109a8086 rev=0x00
hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel PRO/1000 PL Network Adaptor (82573L)'
class = network
subclass = ethernet
bar [10] = type Memory, range 32, base 0xdc300000, size 131072, enabled
bar [18] = type I/O Port, range 32, base 0x3000, size 32, enabled
cap 01[c8] = powerspec 2 supports D0 D3 current D0
cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message
cap 10[e0] = PCI-Express 1 endpoint max data 128(256) link x1(x1)
This is the sort of output we're looking for.
