%description
A linux kernel module implementing the data channel of the OpenVPN protocol in
the linux kernel.

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.
