NAME
       dev_alloc_skb - allocate an skbuff for sending


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 in there is no free memory.  Although  this  function
       allocates memory it can be called from an interrupt.
