Hello Jason,

yes this works indeed thank you!

This means however that NEON SIMD instructions are not used, right ? The
datasheet of the board mentions that it includes the NEON SIMD coprocessor
: https://dn.odroid.com/S805/Datasheet/S805_Datasheet%20V0.8%2020150126.pdf

And CONFIG_NEON=y is activated in the kernel. Forgive me, I don't know much
about what it means for the wireguard module not using the neon simd
instructions.

Best Regards,
Philipp Richter
