      ixgbe: Use watchdog check in favor of BPF for detecting latched timestamp · 6cb562d6
      Jacob Keller authored
      This patch removes ixgbe_ptp_match, and the corresponding packet filtering from
      ixgbe driver. This code was previously causing some issues within the hotpath of
      the driver. However the code also provided a check against possible frozen Rx
      timestamp due to dropped packets when the Rx ring is full. This patch provides a
      replacement solution based on the watchdog.
      To this end, whenever a packet consumes the Rx timestamp it stores the jiffy
      value in the rx_ring structure. Watchdog updates its own jiffy timer whenever
      there is no valid timestamp in the registers.
      If watchdog detects a valid timestamp in the registers, (meaning that no Rx
      packet has consumed it yet) it will check which time is most recent, the last
      time in the watchdog, or any time in the rx_rings. If the most recent "event"
      was more than 5seconds ago, it will flush the Rx timestamp and print a warning
      message to the syslog.

      net/intel: remove __dev* attributes · 9f9a12f8
      Bill Pemberton authored
      CONFIG_HOTPLUG is going away as an option.  As result the __dev*
      markings will be going away.
      Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
      and __devexit.

      ixgbe: add setlink, getlink support to ixgbe and ixgbevf · 815cccbf
      John Fastabend authored
      This adds support for the net device ops to manage the embedded
      hardware bridge on ixgbe devices. With this patch the bridge
      mode can be toggled between VEB and VEPA to support stacking
      macvlan devices or using the embedded switch without any SW
      component in 802.1Qbg/br environments.
      Additionally, this adds source address pruning to the ixgbevf
      driver to prune any frames sent back from a reflective relay on
      the switch. This is required because the existing hardware does
      not support this. Without it frames get pushed into the stack
      with its own src mac which is invalid per 802.1Qbg VEPA
