Detect AES-NI hw encryption also if no cpu flags for AES-NI is present
This ticket is to Detect AES-NI hw encryption also if no cpu flags for AES-NI is present following the testing that has been reported on tor-talk mailing list https://lists.torproject.org/pipermail/tor-talk/2017-August/043450.html .
It seems that a lot of VPS may be able to use AES-NI hardware encryption acceleration, also when CPU flags are not passed by the hypervisor, if we find a way to test the availability of AES-NI presence.
