From: Ido Schimmel <idosch@nvidia.com> Petr says: The RED qdisc can expose number of packets that it has marked through the prob_marked counter (shown in iproute2 as "marked"). This counter currently just shows number of packets marked in the SW datapath, which in a switch deployment likely means zero. Spectrum-3 does support per-TC counters, and in this patchset, mlxsw supports this RED statistic properly. Patches #1 and #2 fix typos. Patch #3 adds a field ecn_marked_tc to the PPCNT register. Patch #4 adds the support to publish the value of ecn_marked_tc through the prob_marked RED qdisc counter. Patch #5 adds selftests.
