SYNOPSIS
struct sk_buff * skb_clone(struct sk_buff * skb, gfp_t 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.
