skb_recycle_check — check if skb can be reused for receive
bool skb_recycle_check ( | struct sk_buff * skb, |
int skb_size); |
Checks that the skb passed in is not shared or cloned, and
that it is linear and its head portion at least as large as
skb_size so that it can be recycled as a receive buffer.
If these conditions are met, this function does any necessary
reference count dropping and cleans up the skbuff as if it
just came from __alloc_skb.
