When I look at /proc/interrupts:

$ cat /proc/interrupts
           CPU0       CPU1
(...)
 12:          4          0    IO-APIC-edge  i8042
 14:        145   65310875    IO-APIC-edge  ide0
 50:          0          0   IO-APIC-level  uhci_hcd:usb5, Intel ICH7
 58:       5388    7983508   IO-APIC-level  libata
169:  812427252 1236572641   IO-APIC-level  skge, eth1
217:          6          0   IO-APIC-level  ehci_hcd:usb1, uhci_hcd:usb2
225:          0          0   IO-APIC-level  uhci_hcd:usb3
233:         60 3108720778   IO-APIC-level  uhci_hcd:usb4, skge

I can see two skge and one eth1 entries. All of them are the network cards. Because of the general name "skge" (which is the name of the network driver of the card) I can't easily reocognize, which NIC occupies which interrupt.

How to make linux use more descriptive names in the entries?

Or: Is there any alternative way to obtain INT information instead of /proc/interrupt?

My final goal is to manipulate smp_affinities of the NICs.
