- According our investigation collapsing skb in socket write queue significantly increases perfomance for small responses. - Fix `tcp_can_coalesce_send_queue_head`. We should make Tempesta FW checks before checking `len <= skb->len`. - We should also check `SKBTX_SHARED_FRAG` flag because collapsing skbs with defferent value of this flag is prohibited.
