From cfab13aa93897524a4c8d4f6e30d91e7dd9e247b Mon Sep 17 00:00:00 2001 From: Shahed Shaikh Date: Thu, 7 Jun 2018 09:30:52 -0700 Subject: [PATCH] net/qede: fix link change event notification As per existing behavior, when firmware sends a link change notification, PMD only updates the link structure but does not notify applications about it. This results in application sending packets even when link status is down. Fix this issue by issuing RTE_ETH_EVENT_INTR_LSC.
