From: gabriele paoloni <gabriele.paoloni@huawei.com> This patchset is based on Casey's patchset: https://www.spinics.net/lists/arm-kernel/msg578927.html It is a proposal to convert the ixgbe driver to disable RO at runtime depending on the root port flags. TODO: Casey's patchset above add quirks to disable RO only for Intel E5-26xx and AMD ARM A1100, whereas currently the Intel ixgbe driver disable RO by default. Therefore there may be some other host quirks to be added in drivers/pci/quirks.... gabriele paoloni (2): net: revert commit 1a8b6d76dc5b net: ixgbe: disable RO depending on the root port flags arch/Kconfig | 3 --- arch/sparc/Kconfig | 1 - drivers/net/ethernet/intel/ixgbe/ixgbe_common.c | 35 ++++++++++++++----------- 3 files changed, 20 insertions(+), 19 deletions(-) -- 2.7.4
