Re: the mapping of eth devices to modules

[Nic Ferrier <nferrier@tapsellferrier.co.uk>]

Following up on whether it's possible to work out the mapping between
modules and the network devices they are driving.

For the PCI bus the information is in the sysfs file system:

  $ ls -l /sys/class/net/eth0

  total 0
  drwxr-xr-x  3 root root    0 Mar  3 14:31 .
  drwxr-xr-x  5 root root    0 Mar  3 14:37 ..
  -r--r--r--  1 root root 4096 Mar  3 14:31 addr_len
  -r--r--r--  1 root root 4096 Mar  3 14:31 address
  -r--r--r--  1 root root 4096 Mar  3 14:31 broadcast
  lrwxrwxrwx  1 root root    0 Mar  3 14:31 device -> ../../../devices/pci0000:00/0000:00:0a.0
  lrwxrwxrwx  1 root root    0 Mar  3 14:31 driver -> ../../../bus/pci/drivers/3c59x
  -r--r--r--  1 root root 4096 Mar  3 14:31 features
  -rw-r--r--  1 root root 4096 Mar  3 14:31 flags
  -r--r--r--  1 root root 4096 Mar  3 14:31 ifindex
  -r--r--r--  1 root root 4096 Mar  3 14:31 iflink
  -rw-r--r--  1 root root 4096 Mar  3 14:31 mtu
  drwxr-xr-x  2 root root    0 Mar  3 14:31 statistics
  -rw-r--r--  1 root root 4096 Mar  3 14:31 tx_queue_len
  -r--r--r--  1 root root 4096 Mar  3 14:31 type

Unfortunately the same information doesn't seem to be present for
cards sat on the PCMCIA bus. I don't know about the USB bus.


But it's something.
