From 555a842811cb5df0774ea7ff59e9c73f30ca0c11 Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Thu, 8 Aug 2013 21:02:22 +0800 Subject: [PATCH] bnx2: clean up unnecessary MSI/MSI-X capability find PCI core will initialize device MSI/MSI-X capability in pci_msi_init_pci_dev(). So device driver should use pci_dev->msi_cap/msix_cap to determine whether the device support MSI/MSI-X instead of using pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will consume more time. Signed-off-by: Yijing Wang Cc: Michael Chan Cc: netdev@vger.kernel.org Signed-off-by: David S.
