The logic for dynamic ITR update is confusing at best as there were odd paths chosen for how to find the rings associated with a given queue based on the vector index and other inconsistencies throughout the code. This patch is an attempt to clean up the logic so that we can more easily understand what is going on. Specifically if there is a Rx or Tx ring that is enabled in dynamic mode on the q_vector it is allowed to override the other side of the interrupt moderation. While it isn't correct all this patch is doing is cleaning up the logic for now so that when we come through and fix it we can more easily identify that this is wrong. The other big change made here is that we replace references to: vsi->rx_rings[q_vector->v_idx]->itr_setting with: q_vector->rx.ring->itr_setting The general idea is we can avoid the long pointer chase since just accessing q_vector->rx.ring is a single pointer access versus having to chase down vsi->rx_rings, and then finding the pointer in the array, and finally chasing down the itr_setting from there.
