net/mlx5e: Avoid reset netdev stats on configuration changes
Move all RQ, SQ and channel counters from the channel objects into the priv structure. With this change, counters will not be reset upon channel configuration changes. Channel's statistics for SQs which are associated with TCs higher than zero will be presented in ethtool -S, only for SQs which were opened at least once since the module was loaded (regardless of their open/close current status). This is done in order to decrease the total amount of statistics presented and calculated for the common out of box use (no QoS). mlx5e_channel_stats is a compound of CH,RQ,SQs stats in order to create locality for the NAPI when handling TX and RX of the same channel. Align the new statistics struct per ring to avoid several channels update to the same cache line at the same time. Packet rate was tested, no degradation sensed.
