[dpdk-dev] [PATCH 03/14] ethdev: remove legacy EtherType filter type support

[Andrew Rybchenko <arybchenko@solarflare.com>]

RTE flow API should be used for filtering.

Move corresponding definitions to ethdev internal driver API
since it is used by drivers internally.
Preserve RTE_ETH_FILTER_ETHERTYPE because of it as well.
