    dco: backport immediate notification processing on Linux and FreeBSD
    
    Backport the immediate DCO message processing model from commit 7791f53
    ("dco: process messages immediately after read").
...
    Github: OpenVPN/openvpn#900
    Github: OpenVPN/openvpn#918
    Github: OpenVPN/openvpn#931
    Github: fixes OpenVPN/openvpn#919
    Github: closes OpenVPN/openvpn#945

... and this went into 2.6.20 release.
