In current HNS3 PMD, Rx/Tx bytes from packet stats are not implemented.
This patch implemented Rx/Tx bytes using soft counters. Rx/Tx bytes stats will be enabled if the macro RTE_LIBRTE_HNS3_PMD_SOFT_COUNTERS is defined.

Why statistics enabled only with macro? It is not common to use macro to enable the stats, what do you think to remove it, to be consistent with rest of the PMDs?
Firstly, the macro is used to control the statistics to ensure performance and facilitate flexible usage. For example, the macro needs to be disabled when high performance is required. The byte statistics of other vendors are implemented by reading and writing registers. Macro is also used, for example, mlx4.
