These functions are 'static inline', no need to be exported in the
.map. And the macros like 'PKT_RX_DYNF_PROTO_XTR_XXX', in fact, their
real definitions are global values defined in rte_pmd_ice like:
rte_net_ice_dynflag_proto_xtr_xxx_mask.

Since rte_pmd_ice are required to compiled as a shared library, so
it is needed to export these flags and field in the .map.

This design is referred to the below upstream practice about dynamic
mbuf.
