      [PATCH] New PowerPC 4xx on-chip ethernet controller driver · 37448f7d
      Eugene Surovegin authored
      This patch replaces current PowerPC 4xx EMAC driver with
      new, re-written from the scratch version. This patch is quite big
      (~234K) because there is virtualy 0% of common code between old and
      new version.
      
      New driver uses NAPI, it solves stability problems under heavy packet
      load and low memory, corrects chip register access and fixes numerous
      small bugs I don't even remember now.
      
      This patch has been tested on all supported in 2.6 PPC 4xx boards.
      It's been used in production for almost a year now on custom
      4xx hardware. PPC32 specific parts are already upstream.
      
      Patch was acked by the current EMAC driver maintainer (Matt Porter). I
      will be maintaining this new version.
