This Pull Request enables the OpenVPN data channel offload kernel module, which was first released in Linux 6.16.
Why
This module "replaces" the Debian package openvpn-dco-dkms, which was providing data channel offload capability prior to Linux 6.16.
The current openvpn-dco-dkms Debian Trixie package fails to build its kernel module when using the 6.18 kernel headers, hence since the kernel 6.18 upgrade, OpenVPN data channel offload is not available on Raspberry Pi OS.
OpenVPN 2.7 can be installed from the trixie-backports in order to use the built-in ovpn kernel module.
The Debian project enabled this module with the commit https://salsa.debian.org/kernel-team/linux/-/commit/3a80e1587a3d0656addc078044c0771e0d37318b
What
When built using
bcm2711_defconfig, the kernel moduleovpn.kofile size is 128216 bytes.
