struct sk_buff * __dev_alloc_skb(unsigned int length, gfp_t gfp_mask);
length to allocate
get_free_pages mask, passed to alloc_skb
Allocate a new sk_buff and assign it a usage count of one. The buffer
has unspecified headroom built in. Users should allocate the headroom
they think they need without accounting for the built in space. The
built in space is used for optimisations.
NULL is returned if there is no free memory.
