[dpdk-dev] [PATCH 10/14] ethdev: remove legacy L2_TUNNEL filter type support

[Andrew Rybchenko <arybchenko@solarflare.com>]

RTE flow API should be used for filtering.

Preserve RTE_ETH_FILTER_L2_TUNNEL since it is used in drivers
internally in RTE flow API support.

rte_eth_l2_tunnel_conf structure is used in other ethdev API
functions.
