>
> The ice_qp_reset_stats function resets the stats for all rings on a VSI. It currently behaves differently for Tx and Rx rings. For Rx rings, it only clears the rx_stats which do not include the pkt and byte counts. For Tx rings and XDP rings, it clears only the pkt and byte counts.
>
> We could add extra memset calls to cover both the stats and relevant tx/rx stats fields. Instead, lets convert stats into a struct_group which contains both the pkts and bytes fields as well as the Tx or Rx stats, and remove the ice_q_stats structure entirely.
>
> The only remaining user of ice_q_stats is the ice_q_stats_len function in ice_ethtool.c, which just counts the number of fields. Replace this with a simple multiplication by 2. I find this to be simpler to reason about than relying on knowing the layout of the ice_q_stats structure.
>
> Now that the stats field of the ice_ring_stats covers all of the statistic values, the ice_qp_reset_stats function will properly zero out all of the fields.
