This is GRO in combination with a pcrypt parallelized
crypto algorithm, without the parallelization GRO/GSO
does not help because crypto is the bottleneck then.

I've pushed it to
https://git.kernel.org/cgit/linux/kernel/git/klassert/linux-stk.git/log/?h=net-next-ipsec-offload
It is just example code, nothing that I would show usually.
But you asked for it, so here is it :)
The GRO part seems to work well, the GSO part is just a hack at the
