  Log:
  If bpf(4) has not been compiled into the kernel, initialize the bpf interface
  pointer to a zeroed, statically allocated bpf_if structure. This way the
  LIST_EMPTY() macro will always return true. This allows us to remove the
  additional unconditional memory reference for each packet in the fast path.
