While it was convenient to have a generic ring structure that served both Tx and Rx sides, next commits are going to introduce several Tx-specific fields, so in order to avoid hurting the Rx side, let's pull out the Tx ring onto new ice_tx_ring and ice_rx_ring structs. Rx ring could be handled by the old ice_ring which would reduce the code churn within this patch, but this would make things asymmetric. Make the union out of the ring container within ice_q_vector so that it is possible to iterate over newly introduced ice_tx_ring. Remove the @size as it's only accessed from control path and it can be calculated pretty easily. Change definitions of ice_update_ring_stats and ice_fetch_u64_stats_per_ring so that they are ring agnostic and can be used for both Rx and Tx rings. Sizes of Rx and Tx ring structs are 256 and 192 bytes, respectively. In Rx ring xdp_rxq_info occupies its own cacheline, so it's the major difference now.
