Subject: [PATCH 075/124] wireguard: Kconfig: select parent dependency for
 crypto

commit d7c68a38bb4f9b7c1a2e4a772872c752ee5c44a6 upstream.

This fixes the crypto selection submenu depenencies. Otherwise, we'd
wind up issuing warnings in which certain dependencies we also select
couldn't be satisfied. This condition was triggered by the addition of
the test suite autobuilder in the previous commit.

kernel: 5.4: import wireguard backport Rather than using the clunky, old, slower wireguard-linux-compat out of tree module, this commit does a patch-by-patch backport of upstream's wireguard to 5.4. This specific backport is in widespread use, being part of SUSE's enterprise kernel, Oracle's enterprise kernel, Google's Android kernel, Gentoo's distro kernel, and probably more I've forgotten about. It's definately the "more proper" way of adding wireguard to a kernel than the ugly compat.h hell of the wireguard-linux-compat repo. And most importantly for OpenWRT, it allows using the same module configuration code for 5.10 as for 5.4, with no need for bifurcation. These patches are from the backport tree which is maintained in the open here: https://git.zx2c4.com/wireguard-linux/log/?h=backport-5.4.y I'll be sending PRs to update this as needed.
