svn commit: r244663 - stable/9

[Adrian Chadd]

It's an interesting discussion to have (after the new year, of course.)

I understand that we sometimes have to change ABIs because we can't
fix problems otherwise. However, I don't recall seeing much/any
discussion about this. If it appeared on a list that I didn't spot
then cool. But any kind of ABI change in a stable branch deserves a
little more discussion before its done.

The reason ath(4) 802.11n support isn't in -9 is because of the ABI
changes I'd have to do to net80211 (at least) before I could put it
in, and I want to make sure all of my changes are in place before I do
(hopefully one, maybe two) large-scale changes.
