Dave please revert the following patch because it is being fixed
without a software workaround:

    ixgbe: disable MSI-X by default on certain Cisco adapters

    Due to an errata in 82598 parts MSI-X needs to be disabled
    in certain ixgbe devices designed to transfer peer-to-peer
    traffic on the PCIe bus. This patch sets the default
    interrupt type to MSI rather than MSI-X for specific Cisco
    ixgbe adapters.
