  To fill the gap with linux kernel eBPF implementation,
add support for two non-generic instructions:
(BPF_ABS | <size> | BPF_LD) and (BPF_IND | <size> | BPF_LD)
which are used to access packet data.
Make necessary changes in BPF verifier, interpreter and x86 JIT code.

Konstantin Ananyev (5):
  test/bpf: fix few small issues
  bpf: fix add/sub min/max estimations
  bpf: add support for packet data load instructions
  test/bpf: add new test cases for mbuf load instructions
  bpf: x86 JIT support for packet data load instructions
