[PATCH 0/4] rte_ethdev: cleanups

[Stephen Hemminger]

A bunch of small (almost trivial) patches to fix style and other
issues in the base Ethernet driver interface code.

Stephen Hemminger (4):
  rte_ethdev: remove extra inline
  rte_ethdev: whitespace cleanup
  rte_ethdev: make tables const
  rte_ethdev: remove unnecessary paren on return

[PATCH 1/4] rte_ethdev: remove extra inline

[Stephen Hemminger]

There is no reason to inline functions that are not in the critical
path.

Partial NAK for now. Mostly this looks ok, but I disagree with the changes to
the indentation of continued lines. Until we get agreement on what the standard
way of doing this on DPDK is, making these changes is premature. [Plus I like
the existing way of double-tab :-)].
