They use it?
No one did bother to send a patch for the in-kernel Libertas
driver during the last year. Sigh.
Also, if they use it, they need a patch on top of what is now in
the kernel, because the current in-kernel libertas driver has no
code to issue the CMD_802_11_LED_GPIO_CTRL. That's why I removed
it in the first place.
It's O.K. for me to keep this code in (it doesn't harm), but a
better approach would be
a) use a new-style commands, a.k.a. lbs_cmd_with_response()
b) use the in-kernel LED support (as you said)

It's actually used by the OLPC folks; but right now there's simply no
mechanism to configure that ability via WEXT. Is there some way to do
this via the kernel LED framework instead that libertas should be
using?

Because it was a WEXT private ioctl and I ripped those all out and told
them no. They still patch that (because there wasn't a LED framework at
the time) into the OLPC Gen 1 kernel trees. Not sure they are ever
going to jump to 2.6.32 or anything though. Just letting you know.
There's quite a few commands that only the OLPC stuff uses, but because
there was no usable userland interface for it (because we said no to
IWPRIV, and because debugfs is for debugging only) they just stuck with
IWPRIV and patched that in.

I was working on that and had converted all but 7 of the old-style
commands before you started the cfg80211 work, and now I figure after
you're done I'd go back and clean them up if they still exist.

Yeah, that's obviously what should be done.
