    This patchset introduces the following:
    1. A new placement policy of Tx headers and descriptors, which takes
    advantage of an option to place headers + descriptors in device memory
    space. This is sometimes referred to as LLQ - low latency queue.
    The patch set defines the admin capability, maps the device memory as
    write-combined, and adds a mode in transmit datapath to do header +
    descriptor placement on the device.
    2. Support for RX checksum offloading
    3. Miscelaneous small improvements and code cleanups
