ARRAY_SIZE is not defined only in tap_bpf_insns.c.
Please note ARRAY_SIZE is used several times in tap_flow.c as well.

Please note that file tap_bpf_program.c is the C source code for the bytecode.
The plan for next release (18.05) is:
1. Ask the user to install clang version 3.7 in order to compile the C source
into BPF assembly object file
2. Supply a tool that will generate the bytecode from the object file
3. Advanced option: use the generated bytecode to transparently compile TAP PMD
If a user is reluctant to install clang 3.7 he has the option to compile TAP
PMD without external tool dependency.
For this release please confirm the bytecode alone without the tool (expected
in next release)
