IEEE 802.11-2012 added support for Extended Key ID, allowing pairwise keys to also use keyID 1 and moving group keys to IDs 2 and 3.
Support for Extended Key ID is basically completed and confirmed working with both hwsim and "on the air" with ath9k/iwldvm using software encryption and those patches here. (The corresponding patch for wpa_supplicanat/hostapd need some more work, but that's mostly cleanup and support for STKSAs.) Prior to propose this patch for merging I would like to get Extended Key ID working with HW encryption for at least some devices, but after experimenting with ath9k and to a lesser extend with ath10k it's now clear that this will be an per-driver effort and it may well turn out to be impossible without firmware updates. So I've decided to continue working on the HW support for now but also ask you for feedback for what I got so far. Any feedback is welcome and I especially like to learn what you think of the API extensions and what has to be changed to get it merged.
