Wireguard backport to 2.6.3x kernels

[John Wayne]

Hi,

I am working on a project that involves some old MIPS and ARM based
custom boards.
Current SDKs for these boards are pretty messy and there is no
documentation about the
patches that were applied to the 2.6.3x kernels in order make them
work on these boards.

So my question is how painfully will it be to port wireguard to the
even more ancient 2.6.3x kernels?

Thanks!
