Out of the fields {per_napi_bytes, per_napi_packets} in struct ena_ring, + only rx_ring->per_napi_packets are used to determine if napi did work + for dim. + This commit removes all other uses of these fields. +2. Remove ena_ring->moder_tbl_idx, which is not used by dim. +3. Remove all calls to ena_com_destroy_interrupt_moderation(), since all it + did was to destroy the interrupt moderation table, which is removed as + part of removing old interrupt moderation code. + +Signed-off-by: Arthur Kiyanovski <akiyano@amazon.com> +Signed-off-by: David S.
