This reverts commit 436a4e88659842a7cf634d7cc088c8f2cc94ebf5. This as been reported by multiple people [0] that with this commit, broadcast packets were not being delivered after GTK exchange. Qualcomm seems to have a similar patch [1] confirming the issue.
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? Vasanth
