[dpdk-dev] [PATCH] ethdev: fix flow expansion matching types

[Nelio Laranjeiro <nelio.laranjeiro@6wind.com>]

Node RSS types are generally covering more RSS kind than the user is
requesting, it should accept to expand even if only a single bit is
remains after masking.  Setting the correct RSS kind for the rule
remains the driver job.

Fixes: 959823ce4c47 ("ethdev: add flow API to expand RSS flows")
