[dpdk-dev] [PATCH 00/18] ethdev: change link status get functions return value to int

[Andrew Rybchenko <arybchenko@solarflare.com>]

It is the fifth patch series to get rid of void returning functions
in ethdev in accordance with deprecation notice [1].

It should be applied on top of [2], [3], [4] and [5].

Functions which return void are bad since they do not provide explicit
information to the caller if everything is OK or not.

In the case of link info get it is important to know if link info is
filled in or not.

Unlike previous patch series for other functions, this one does not
touch link_update driver callback since it already has return value
with different semantics (which is not used in fact). May be negative
return values should be kept for errors and positive 1 should report
no link status changes. That's why only negative values are treated
as errors in the patch series.
