If you're going to use sysfs, libsysfs can help. It can be found in the sysfsutils package here:
http://linux-diag.sourceforge.net/Sysfsutils.html
[stekloff@... stekloff]$ systool -c net eth0 -D Class = "net"
Class Device = "eth0" Device = "0000:02:01.0" Driver = "e1000" Devices using "e1000" are: Device = "0000:02:01.0"
And more extended output:
[stekloff@... stekloff]$ systool -c net eth0 -v Class = "net" Class Device = "eth0" Class Device path = "/sys/class/net/eth0" addr_len = "6" address = "00:0d:60:c9:42:06" broadcast = "ff:ff:ff:ff:ff:ff" features = "0x3a9" flags = "0x1002" ifindex = "6" iflink = "6" mtu = "1500" tx_queue_len = "1000" type = "1" Device = "0000:02:01.0" Device path = "/sys/devices/pci0000:00/0000:00:1e.0/0000:02:01.0" class = "0x020000" config = 86 80 1e 10 17 01 30 02 03 00 00 02 08 40 00 00 00 00 24 c0 00 00 20 c0 01 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 22 00 00 00 14 10 49 05 00 00 00 00 dc 00 00 00 00 00 00 00 0b 01 ff 00 detach_state = "0" device = "0x101e" irq = "11" resource = "0x00000000c0240000 0x00000000c025ffff 0x0000000000000200 0x00000000c0200000 0x00000000c020ffff 0x0000000000000200 0x0000000000008000 0x000000000000803f 0x0000000000000101 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x000000000000ffff 0x0000000000007200" subsystem_device = "0x0549" subsystem_vendor = "0x1014" vendor = "0x8086" Driver = "e1000" Driver path = "/sys/bus/pci/drivers/e1000" new_id = <store method only> Devices using "e1000" are: "0000:02:01.0"
