This will re-open https://www.spinics.net/lists/hostap/msg08921.html
reported by Sven. The recommended ath firmware ABI during GTK re-keying
is SET_KEY instead of current DEL_KEY followed by SET_KEY. We are looking
at other options like some marking by mac80211 for the driver to be able
to identify if the received DEL_KEY is for re-keying. Also I'm curious
if roaming between secure and non-secure mode is a critical use case.
If not, we can probably go ahead with this revert as temporary WAR,
@Sven?
