[PKT_SCHED]: HTB: Drop packet when direct queue is full
htb_enqueue(): Free skb and return NET_XMIT_DROP if a packet is destined for the direct_queue but the direct_queue is full. (Before this: erroneously returned NET_XMIT_SUCCESS even though the packet was not enqueued) Signed-off-by: Asim Shankar <asimshankar@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
