From: Ilya Lipnitskiy Date: Fri, 19 Feb 2021 16:22:08 +0000 (-0800) Subject: kernel: migrate wireguard into the kernel tree X-Git-Tag: v22.03.0-rc1~3316 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=06351f1bd0455abacb700db5098bb798f66948fc;p=openwrt%2Fstaging%2Fhauke.git kernel: migrate wireguard into the kernel tree On Linux 5.4, build WireGuard from backports. Linux 5.10 contains wireguard in-tree. Add in-kernel crypto libraries required by WireGuard along with arch-specific optimizations.
