Upstream produces a proper independent backport of wireguard for v5.4 based kernels. Due to the nature of the compat version in the DKMS packages some features are not implemented there leading to worse performance. This proper backport is now in use in the majority of distros which use the v5.4 base, and as such support for v5.4 is likely to end soon in the compat tree. Switch to using that backport.
