This announce is related to the discussion regarding TEP and the need for
encap/decap support in rte_flow [1].

It's now clear that PMD support for chaining multiple non-terminating flow
rules of varying priority levels is prohibitively difficult to implement
compared to simply allowing multiple identical actions performed in a
defined order by a single flow rule.
