Is this check requires both spec and mask to be all zeros? If this is
the real intention, can you please add a comment above check to clarify it.

Also other i40e_flow_parse_xxx_pattern() functions has function comment
to describe expected/valid pattern for the flow rule.
i40e_flow_parse_qinq_pattern() is missing that function comment. Would
you mind adding it, which helps to validate implementation against
intention.

Thanks,
ferruh
