NAME
       sk_unattached_filter_create - create an unattached filter

SYNOPSIS
       int sk_unattached_filter_create(struct sk_filter ** pfp, struct sock_fprog * fprog);

ARGUMENTS
       pfp
	   the unattached filter that is created

       fprog
	   the filter program

DESCRIPTION
       Create a filter independent of any socket. We first run some sanity checks on it to make sure it does not explode on us later. If an error
       occurs or there is insufficient memory for the filter a negative errno code is returned. On success the return is zero.
