From 1c1bf34951e8d17941bf708d1901c47e81b15d55 Mon Sep 17 00:00:00 2001 From: Jack Morgenstein Date: Wed, 22 Jul 2015 16:53:47 +0300 Subject: [PATCH] net/mlx4_core: Fix wrong index in propagating port change event to VFs The port-change event processing in procedure mlx4_eq_int() uses "slave" as the vf_oper array index. Since the value of "slave" is the PF function index, the result is that the PF link state is used for deciding to propagate the event for all the VFs. The VF link state should be used, so the VF function index should be used here.
