[dpdk-dev] [PATCH v2] net/bonding: fix update link status on slave add

[Radu Nicolau <radu.nicolau@intel.com>]

Add a call to rte_eth_link_get_nowait on every slave to update
the internal link status struct. Otherwise slave add will fail
for mode 4 if the ports are all stopped but only one of them checked.

Fixes: b77d21cc2364 ("ethdev: add link status get/set helper functions")
Bugzilla entry: https://dpdk.org/tracker/show_bug.cgi?id=52
