This patch adds support of flushing a conntrack entry specified by the conntrack 5-tuple, and provides the implementation in dpif-netlink. The implementation of dpif-netlink in the linux datapath utilizes the NFNL_SUBSYS_CTNETLINK netlink subsystem to delete a conntrack entry in nf_conntrack. Future patches will add support for the userspace and Windows datapaths. VMWare-BZ: #1983178 Signed-off-by: Yi-Hung Wei <yihung.wei@gmail.com> Signed-off-by: Justin Pettit <jpettit@ovn.org>
