Well, I guess it's a question of which userspace even uses it, and how
it'll break.

Perhaps we should modify the wext userspace API to allow 0-254, and add
1 to the value before passing it to the driver. That way, in wext it
would be "compatible" with your expected behaviour, but internally we'd
still use the 802.11 semantics. I'd accept a patch doing this, since
you're the only one to ever even admit to using it (and still using
wext) :-)

Of course we should also fix the driver to treat it as # of transmission
attempts rather than # of retries, since clearly that's required for the
nl80211 API which is documented to do it like the spec.
