Change subject: dco: don't use NetLink to exchange control packets ...................................................................... dco: don't use NetLink to exchange control packets Using NetLink for control messages did not work out as it did lead to kernel side buffer congestion during heavy client activity. With this patch DCO will redirect control packets directly to the transport socket without altering them, so that userspace can happily process them as usual. NOTE: this is an API breaking change. Up to this commit, the userland requests a kernel module called "ovpn-dco" which does control messages via netlink. From this commit on, OpenVPN requests a kernel module named "ovpn-dco-v2" which brings the kernel change corresponding to this commit. If the system only has "the wrong module" available (either way), OpenVPN will log ... Kernel support for ovpn-dco missing, disabling data channel offload. and proceed without kernel support.
