There is no such thing as "traffic group". The group that this is a heading
of is "per traffic class counters". Fix the heading.

The name does not make sense as it is. Clearly there is a typo and the
suffix should have been _CNT, like the other enumerators. Fix accordingly.

The PPCNT register retrieves per port performance counters. The
ecn_marked_tc field in per-TC Congestion counter group contains a count of
packets marked as ECN or potentially marked as ECN.

From: Petr Machata <petrm@nvidia.com>
The Qdisc code in mlxsw used to report a number of packets ECN-marked on a
port. Because reporting a per-port value as a per-TC value was misleading,
this was removed in commit 8a29581eb001 ("mlxsw: spectrum: Move the
ECN-marked packet counter to ethtool").
On Spectrum-3, a per-TC number of ECN-marked packets is available in per-TC
congestion counter group. Add a new array for the ECN counter, fetch the
values from the per-TC congestion group, and pick the value indicated by
tclass_num as appropriate.
On Spectrum-1 and Spectrum-2, this per-TC value is not available, and
zeroes will be reported, as they currently are.
