wpa_supplicant, SAE secured MESH on RT5370 doesn't PING after peer connection is established

[Greg Gigon]

Would you be able to point to the kernel release that includes the mac80211 fixes for mesh? There is a 4.8.y build on Raspibian GitHub, https://github.com/raspberrypi/linux/tree/rpi-4.8.y.
However, I don’t know wether it includes the changes.

Or do you have a link to patch somewhere? Linux Kernel dev is a jungle for me and I don’t how to find the right patches to apply.
Any help would be greatly appreciated !
