If we know that a device has broken parity checking, then disable it. This avoids quirks like in r8169 where on the first parity error interrupt parity checking will be disabled if broken_parity_status is set. Make pci_quirk_broken_parity() public so that it can be used by platform code, e.g. for Thecus N2100. v2: - reduce scope of N2100 change to using the new PCI core quirk v3: - improve commit message of patch 2 Heiner Kallweit (3): PCI: Disable parity checking if broken_parity_status is set ARM: iop32x: improve N2100 PCI broken parity quirk r8169: simplify broken parity handling now that PCI core takes care arch/arm/mach-iop32x/n2100.c | 2 +- drivers/net/ethernet/realtek/r8169_main.c | 14 -------------- drivers/pci/quirks.c | 17 +++++++++++------ include/linux/pci.h | 2 ++ 4 files changed, 14 insertions(+), 21 deletions(-) -- 2.30.0
