      gianfar: Remove sysfs stubs for FIFOCFG and stashing · 34018fd4
      Claudiu Manoil authored
      Removing the sysfs stubs for the Tx FIFOCFG and ATTRELI
      (stashing) config registers, as these registers may only
      be configured after a MAC reset, with the controller stopped
      (i.e. during hw init, at probe() time).  The current sysfs
      stubs allow on-the-fly updates of these registers (the locking
      measures are useless and only add unecessary code).
      
      Changing these registers is discouraged. Only the default values
      will be used instead.
      
      Moreover, the stashing (ATTRELI) configuration options were
      effectively disabled (didn't get to the hw anyway if changed)
      because the stashing device_flags (HAS_BD_STASHING|HAS_BUF_STASHING)
      were "accidentally" cleared during probe().

      * Added sysfs support to gianfar for modifying FIFO and stashing parameters
      * Updated driver to support 10 Mbit, full duplex operation
      * Improved comments throughout
      * Cleaned up and optimized offloading code
      * Fixed a bug where rx buffers were being improperly mapped and unmapped
      * (only manifested if cache-coherency was off)
      * Added support for using the eTSEC exact-match MAC registers
      * Bumped the version to 1.3
      * Added support for distinguishing between reduced 100 and 10 Mbit modes
