      ixgbe: Check PTP Rx timestamps via BPF filter · 1d1a79b5
      Jacob Keller authored
      
      
      This patch fixes a potential Rx timestamp deadlock that causes the Rx
      timestamping to stall indefinitely. The issue could occur when a PTP packet is
      timestamped by hardware but never reaches the Rx queue. In order to prevent a
      permanent loss of timestamping, the RXSTMP(L/H) registers have to be read to
      unlock them. (This used to only occur when a packet that was timestamped
      reached the software.) However the registers can't be read early otherwise
      there is no way to correlate them to the packet.
      
      This patch introduces a filter function which can be used to determine if a
      packet should have been timestamped. Supplied with the filter setup by the
      hwtstamp ioctl, check to make sure the PTP protocol and message type match the
      expected values. If so, then read the timestamp registers (to free them.) At
      this point check the descriptor bit, if the bit is set then we know this
      packet correlates to the timestamp stored in the RXTSTAMP registers.
      Otherwise, assume that packet was dropped by the hardware, and ignore this
      timestamp value. However, we have at least unlocked the rxtstamp registers for
      future timestamping.
      
      Due to the way the driver handles skb data, it cannot be directly accessed. In
      order to work around this, a copy of the skb data into a linear buffer is
      made. From this buffer it becomes possible to read the data correctly

      ixgbe: PTP Fix hwtstamp mode settings · c19197a7
      Jacob Keller authored
      
      
      When enabling the hwtstamp mode for Rx timestamping the V2 ptp event type
      specific modes (Delay Request and Sync) have been rolled into the V2 all event
      packet modes, in order to more accurately represent what hardware is doing.
      Hardware always timestamps the Path delay packets when a V2 mode is selected,
      regardless of what type was selected (in order to always support Path delay
      mode). However this means the user selected modes of timestamping only Sync or
      Delay Request is not truly supported. This patch correctly sets the mode for
      the hwtstamp config and returns to the user that all V2 event packets will be
      timestamped.

      Jacob Keller authored
      
      
      This patch fixes two minor nits from Richard Cochran. The first is a case of
      ambitious line wrapping that wasn't necessary. The second is to re-order the
      flag checks for PPS support. Previously, the hardware test was done first, and
      the interrupt flag test was done second. Now, test the interrupt flag and use
      the unlikely macro.

      ixgbe: align flow control DV macros with datasheet · 4f8a91ad
      John Fastabend authored
      
      
      The flow control DV macros are used to calculate the flow control
      high and low thresholds. This patch annotates these macros slightly
      better and fixes the issues below.
      
      The macro variables are renamed LINK to _max_frame_link and TC to
      _max_frame_tc. This was to avoid confusion and make them more
      readable. It was found that people auditing the code read TC to be
      'traffic class' in the 802.1Q definition instead of the max frame
      size of the tc. Hopefully it is clear now.
      
      This audit also found the following real deviations from the
      theoretical values. Fixed in this patch.
      
        * I multiplied the DV calculations by (36/25) which always
          evaluates to 1. This does not match the intended theoretical
          value of 1.44.
      
        * IXGBE_BT2KB added 1023 to account for rounding however this
          really should be 8 * 1023 - 1 to account for division by 8k.
      
        * x2 multiplication of max frame in DV calculations to account
          for updated hardware recommendations.
      
      With this patch the DV values are inline with the recommendations
      in the 82599 and 82598 data sheets. Its worth noting I did not
      see any dropped frames with flow control on in my experiments without
      this patch. However aligning with the hardware specs and
      recommendations seems like a good idea here to account for worst
      case scenarios.

      Based on a report from Ethan Zhao, before calling register_netdev() the
      driver should be using logging macros that do not display the potentially
      confusing "(unregistered net_device)" yet still display the useful driver
      name and PCI bus/device/function.
