NAME
dev_alloc_skb - allocate an skbuff for receiving
SYNOPSIS
struct sk_buff * dev_alloc_skb(unsigned int length);
ARGUMENTS
length
length to allocate
DESCRIPTION
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. Although this function allocates memory it can be called from an interrupt.
