From 62f8f5ace506b336afcb9022d4c456f893f1d732 Mon Sep 17 00:00:00 2001 From: David Marchand Date: Mon, 22 Jul 2019 14:56:50 +0200 Subject: [PATCH] bus/pci: remove Mellanox kernel driver type This reverts commit 0cb86518db57d35e0abc14d6703fad561a0310e2. The PCI bus now reports DC when faced with a device bound to an unknown driver and, in such a case, the IOVA mode is selected against physical address availability. As a consequence, there is no reason for this special case for Mellanox drivers.
