Backporting KRACK Patches

[Edward Pierzchalski]

Hi all,

I'm currently working in an environment where we only have access to
wpa_supplicant 2.5-devel, and it's infeasible for us to upgrade. I've
had a go at backporting Vanhoef's patches but the methods used to
figure out what state the relevant station's key is in seem to have
been added a while after the latest 2.5 tag.

Is there any news or progress that I've missed re. a backport?

Regards,
