mlxsw: spectrum_qdisc: Introduce per-TC ECN counters
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 8a29581e ("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.
