This allows RSN pre-authentication to be used when roaming decisions are
done in the target.

Thanks, applied.

A cosmetic comment:

> +		ath6kl_dbg(ATH6KL_DBG_WMI, "truncated neighbor event "
> +			   "(num=%d len=%d)\n", ev->num_neighbors, len);

It's preferred that the format string is all in one line like this
(sorry for thunderbird's formatting):

ath6kl_dbg(ATH6KL_DBG_WMI,
	"truncated neighbor event (num=%d len=%d)\n",
	ev->num_neighbors, len);

Latest checkpatch will allow lines over 80 chars when it's like this.

Thanks for the warning, this is always good to know.

John, I merged latest wireless-next to ath6kl-next branch in ath6kl.git
to get the latest cfg80211 changes, I hope that's ok. Let's keep this in
mind when I send the next pull request and double check that I didn't
break anything.
