openvpn-dco-dkms 0.0+git20230816-1ubuntu1 (armhf binary) in ubuntu mantic

 This kernel module allows OpenVPN to offload any data plane management to the
 linux kernel, thus allowing it to exploit any Linux low level API, while
 avoiding expensive and slow payload transfer between kernel space and user
 space. You need a matching dco-enabled OpenVPN to use this, the feature is
 supposed to land in OpenVPN 2.6.
 .
 This package uses DKMS to automatically build the ovpn-dco kernel module.
