My use is purely for testing purposes (being able to use a single /a/b/g/n
chipset to emulate a/b/g stations as well as /n stations.
It appears I have the disable-11n stuff working, and I'm now trying to
figure out how to disable ht40.
Aside from testing, could this perhaps be useful to limiting power
consumption and/or working around strange issues with dodgy APs?
I realize it's a stretch, so if you see no use for it, I'll just
carry the patches in my own trees.
