[dpdk-dev] [PATCH 1/1] net/mlx4: update link status upon probing with lsc
Gaetan Rivet

Fri Mar 3 16:39:56 CET 2017
If LSC interrupts are enabled, the application expects the link_update
ops to be executed by the PMD itself.
No link status change event is received upon probing, therefore the link
status update must be forced.
