From 752a50cab600c6d46c5a1921c6a6d2fb116c8a4b Mon Sep 17 00:00:00 2001 From: Jack Morgenstein Date: Tue, 19 Jun 2012 11:21:33 +0300 Subject: mlx4_core: Pass an invalid PCI id number to VFs Currently, VFs have 0 in their dev->caps.function field. This is a valid pci id (usually of the PF). Instead, pass an invalid PCI id to the VF via QUERY_FW, so that if the value gets accessed in the VF driver, we'll catch the problem.
