If application stacks are expected to keep the skb priority consistent with the dcbx priority the stack will need to be notified when these changes occur. This patch adds application notifiers for the stack to register with. Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
