Subject[PATCH 5.5 007/367] net/core: Do not clear VF index for node/port GUIDs query
Date
From: Leon Romanovsky <leonro@mellanox.com>

[ Upstream commit 9fbf082f569980ddd7cab348e0a118678db0e47e ]

VF numbers were assigned to node_guid and port_guid, but cleared
right before such query calls were issued. It caused to return
node/port GUIDs of VF index 0 for all VFs.

Fixes: 30aad41721e0 ("net/core: Add support for getting VF GUIDs")
