Parece que você pode amarrá-los pelo IRQ.
ifconfig -a
imprimirá os dispositivos Ethernet, incluindo interrupção.
por exemplo.
eth2 Link encap:Ethernet HWaddr 00:25:11:19:8b:77
inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::225:11ff:fe19:8b77/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:39958 errors:0 dropped:0 overruns:0 frame:0

RX bytes:21410099 (21.4 MB) TX bytes:4802798 (4.8 MB)
Interrupt:43 Base address:0xa000
enquanto
lspci -v
fornece as informações PCI com IRQ
por exemplo.
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 01)
Subsystem: Acer Incorporated [ALI] Device 0245
Flags: bus master, fast devsel, latency 0, IRQ 43
I/O ports at e800 [size=256]
Memory at febff000 (64-bit, non-prefetchable) [size=4K]
Expansion ROM at febc0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: r8169
Kernel modules: r8169
desde que eu vejo ambos são 43 eu posso inferir que eth2
combina04:00.0
lspci
