[dpdk-dev] [PATCH v2 1/1] ixgbe: Fix phy errors in stats->ierrors

[Balazs Nemeth]

> Fixes: f6bf669b990004dc69231476d9fcf0b80574e568. Bug fix to remove
> (rxnfgpc - hw_stats->gprc) which does not account for phy errors.
> 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:
>  - specified the commit that this bug fix fixes
