[dpdk-dev] [PATCH v3 2/7] net/mrvl: query link status using library API

[Tomasz Duszynski <tdu@semihalf.com>]

Up to now link status was updated unconditionally during
link_up()/link_down() calls thus one was never sure about
it's true status.

Using dedicated library api makes sure the true link status is set.
