    We are pleased to announce a new Gigabit Ethernet product and its
    driver to the linux community. This product is the Intel(R) 82575
    Gigabit Ethernet adapter family. Physical adapters will be available
    to the public soon. These adapters come in 2- and 4-port versions
    (copper PHY) currently. Other variants will be available later.
    
    The 82575 chipset supports significantly different features that
    warrant a new driver. The descriptor format is (just like the
    ixgbe driver) different. The device can use multiple MSI-X vectors
    and multiple queues for both send and receive. This allows us to
    optimize some of the driver code specifically as well compared to
    the e1000-supported devices.
    
    This version of the igb driver no lnger uses fake netdevices and
    incorporates napi_struct members for each ring to do the multi-
    queue polling. multi-queue is enabled by default and the driver
    supports NAPI mode only.
    
    All the namespace collisions should be gone in this version too. The
    register macro's have been condensed to improve readability.
