Subject: [PATCH] net/qede: fix link change event notification

[ backported from upstream commit cfab13aa93897524a4c8d4f6e30d91e7dd9e247b ]

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.

Fixes: ec94dbc57362 ("qede: add base driver")
