• 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.

• 86af8b419   Add sample for adding simple drop program to link ... Browse Code »

  Add a sample program that only drops packets at the BPF_PROG_TYPE_XDP_RX
  hook of a link. With the drop-only program, observed single core rate is
  ~20Mpps.

  Other tests were run, for instance without the dropcnt increment or
  without reading from the packet header, the packet rate was mostly
  unchanged.
