From 7ecf6d8ff154e6f7471ee537a400d43a5f3b1c57 Mon Sep 17 00:00:00 2001 From: Bodong Wang Date: Tue, 30 May 2017 10:18:24 +0300 Subject: IB/mlx5: Restore IB guid/policy for virtual functions When a user sets port_guid, node_guid or policy of an IB virtual function, save this information in "struct mlx5_vf_context". This information will be restored later when pci_resume is called. To make sure this works, one can use aer-inject to generate PCI errors on mlx5 devices and verify if relevant fields are restored after PCI resume.
