NAME
       netdev_alloc_skb - allocate an skbuff for rx on a specific device

SYNOPSIS
       struct sk_buff * netdev_alloc_skb(struct net_device * dev, unsigned int length);

ARGUMENTS
       dev
           network device to receive on

       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.
