I was planning to add an union on skc_tx_queue_mapping and
sk_max_ack_backlog, so that adding a check on sk_max_ack_backlog in
listener lookup would not add an additional cache line miss.
This would remove false sharing because sk_ack_backlog is often dirtied
when a socket is added into accept queue.
