The code that registers the dynamic fields and flags for timestamp is
more or less duplicated several times in the patchset. As discussed
privately, it would make sense to have helpers to register them in one
operation, without the need to redeclare the structures:

  int rte_mbuf_dyn_rx_timestamp_register(int *offset, uint64_t *rx_bitnum)
  int rte_mbuf_dyn_tx_timestamp_register(int *offset, uint64_t *tx_bitnum)
