Change the get_ring_selector hw_ops callback signature from get_ring_selector(struct sk_buff *skb) to get_ring_selector(u8 ac), removing the dependency on the skb. After the previous patch switched WCN6750 from skb_get_hash() to skb_get_queue_mapping(), all get_ring_selector implementations fall into two categories: - smp_processor_id(): ignores the skb entirely - skb_get_queue_mapping(): only reads the AC value from the skb Since the AC is the only information extracted from the skb, pass it directly as a u8 parameter instead. Callers in the dp_tx path now pass skb_get_queue_mapping(skb), which preserves the exact same behavior. This change enables a subsequent patch to call get_ring_selector() from wake_tx_queue using txq->ac, without needing access to the skb. mac80211 guarantees that skb_get_queue_mapping(skb) == txq->ac for any skb dequeued from a given txq, since both values are derived from the same skb->priority through the same AC mapping. No functional change.
