HSR/PRP LRE Stats - What is the right user space interface?

[Murali Karicheri]

Hi Netdev experts,

IEC-62439 defines following LRE stats:-

        "lreTxA",
        "lreTxB",
        "lreTxC",
        "lreErrWrongLanA",
        "lreErrWrongLanB",
        "lreErrWrongLanC",
        "lreRxA",
        "lreRxB",
        "lreRxC",
        "lreErrorsA",
        "lreErrorsB",
        "lreErrorsC",
        "lreNodes",
        "lreProxyNodes",
        "lreUniqueRxA",
        "lreUniqueRxB",
        "lreUniqueRxC",
        "lreDuplicateRxA",
        "lreDuplicateRxB",
        "lreDuplicateRxC",
        "lreMultiRxA",
        "lreMultiRxB",
        "lreMultiRxC",
        "lreOwnRxA",
        "lreOwnRxB",

These stats are defined also in the IEC-62439 MIB definition. So
this MIB support is required in Net-SNMP and that requires a proper
kernel interface to pull the values from the HSR or PRP
LRE (Link Redundancy Entity). What is the right interface for this?
Internally TI uses /proc interface for this. But want to check with
community before sending a patch for this. One choice is ethtool for
this. Or something else? Would appreciate if someone can clarify so
that I can work towards a patch for the same.
