Patch 11: you need to answer my question about this.

[This is about why/whether there should be a fallback from creating an
AF_INET socket to issue SIOCETHTOOL on.]

I looked a little further, and found:
- The only address/protocol family that is always present in the kernel
  (assuming CONFIG_NET=y) is netlink
- Netlink sockets don't support ioctl at all

So there seems to be no right answer to 'which family of socket should
I create to perform device ioctls'.  There really ought to be!

If at first you don't succeed, you're doing about average.
