Hi Raghu,

I'd also be interested in using SAE H2E on OpenWrt 19.07, which is
based on hostapd from 2019-08-08 (ca8c2bd28ad).

Do you have a list of patches you ported to hostap 2.9? With
"git log --oneline --all --grep='H2E'" I get a list of 65 patches
(or 42 without the tests), but I'm not sure if they'd be
sufficient.
