> hw_stats->gprc is the Number of good (non-erred) Rx packets (from the
> network) that pass L2 filtering and has a legal length as defined by
> LongPacketEnable. While rxnfgpc is the Number of good (non-erred with legal
> length) Rx packets (from the network) regardless of packet filtering and receive
> enablement. Thus hw_stats->gprc can be > rxnfgpc and this calculation should
> be removed from the calculation of ierrors.
> Validated with testpmd by sending packets to the interface without forwarding
> enabled - packets should be dropped and the error counters incremented.

> v2:
