[dpdk-dev] [PATCH 3/5] net/mlx5: switch encap rules to use container

[Viacheslav Ovsiienko]

The VXLAN encapsulation neigh/local rules will use
the new introduced structure, which keeps the
rules lists, related to specified outer interface,
instead of attached VTEP structure. It allows us to
unbind VTEP structure from keeping the rules for
interface.
