• d9094bda5   bpf: make xdp sample variable names more meaningful ... Browse Code »

  The naming choice of index is not terribly descriptive, and dropcnt is
  in fact incorrect for xdp2. Pick better names for these: ipproto and
  rxcnt.

• 764cbccef   bpf: add sample for xdp forwarding and rewrite ... Browse Code »

  Add a sample that rewrites and forwards packets out on the same
  interface. Observed single core forwarding performance of ~10Mpps.

  Since the mlx4 driver under test recycles every single packet page, the
  perf output shows almost exclusively just the ring management and bpf
  program work. Slowdowns are likely occurring due to cache misses.
