From e82760e7d6498d24d1a92f22767ba578c8980a6d Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Mon, 27 Jun 2011 07:44:43 +0000 Subject: [PATCH] bnx2: 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. Also, pci_is_pcie is a better way of determining if the device is PCIE or not (as it uses the same saved PCIE capability offset). Signed-off-by: Jon Mason Signed-off-by: David S.
