      igb: PCI-Express 82575 Gigabit Ethernet driver · 9d5c8243
      Auke Kok authored
      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.
