NAME
       skb_kill_datagram - Free a datagram skbuff forcibly

SYNOPSIS
       int skb_kill_datagram(struct sock * sk, struct sk_buff * skb, unsigned int flags);

ARGUMENTS
       sk
	   socket

       skb
	   datagram skbuff

       flags
	   MSG_ flags

DESCRIPTION
       This function frees a datagram skbuff that was received by skb_recv_datagram. The flags argument must match the one used for
       skb_recv_datagram.

       If the MSG_PEEK flag is set, and the packet is still on the receive queue of the socket, it will be taken off the queue before it is freed.

       This function currently only disables BH when acquiring the sk_receive_queue lock. Therefore it must not be used in a context where that
       lock is acquired in an IRQ context.

       It returns 0 if the packet was removed by us.
