Ohh, is this still about a heavily-updated and rewritten version
of my old initial patch from 2014 for 3.16-wl?
<https://lore.kernel.org/linux-wireless/1518134.xFh23iA8q1@blech/>
Because back in 2016, I've asked this on linux-wireless:
| It would be a great if mac80211 would do to the encryption and
| decryption asynchronously. As this would work for other ciphers
| and also allows crypto offload to dedicated crypto hardware.
And the answer back then (same as now) was:

Ben, keep up the good work!
Cheers,
