skb_clone -- duplicate an sk_buff
Synopsis
struct sk_buff * skb_clone (struct sk_buff * skb, int gfp_mask);
Arguments
- skb
buffer to clone
- gfp_mask

Description
Duplicate an &sk_buff. The new one is not owned by a socket. Both
copies share the same packet data but not structure. The new
buffer has a reference count of 1. If the allocation fails the
function returns NULL otherwise the new buffer is returned.
If this function is called from an interrupt gfp_mask must be
GFP_ATOMIC.
