SKB_DST_SET_NOREF(9)						 Linux Networking					      SKB_DST_SET_NOREF(9)

NAME
       skb_dst_set_noref - sets skb dst, hopefully, without taking reference

SYNOPSIS
       void skb_dst_set_noref(struct sk_buff * skb, struct dst_entry * dst);

ARGUMENTS
       skb
	   buffer

       dst
	   dst entry

DESCRIPTION
       Sets skb dst, assuming a reference was not taken on dst. If dst entry is cached, we do not take reference and dst_release will be avoided
       by refdst_drop. If dst entry is not cached, we take reference, so that last dst_release can destroy the dst immediately.
