From a875a4c7404c8e259236b650136b8a603923daf9 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Mon, 27 Jun 2011 07:42:17 +0000 Subject: [PATCH] mlx4: remove unnecessary read of PCI_CAP_ID_EXP The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it. Signed-off-by: Jon Mason Signed-off-by: David S.
