[dpdk-dev] [PATCH 3/8] net/qede: fix to update device link structure

[Rasesh Mody <rasesh.mody@cavium.com>]

8ea656f8c app/testpmd: request link status interrupt
requires QEDE PMD to populate the device link structure without
having to query the driver for link status change event.
This patch updates the device link structure when link status event is
received.
Remove unused param from qed_link_update()

Fixes: 86a2265e59d7 ("qede: add SRIOV support")
Fixes: ec94dbc57362 ("qede: add base driver")
Cc: stable@dpdk.org
