====================
net: stmmac: further cleanups

This small series does further cleanups to the stmmac driver:

1. Name priv->pause to indicate that it's a timeout and clarify the
   units of the "pause" module parameter
2. Remove useless priv->flow_ctrl member and deprecate the useless
  "flow_ctrl" module parameter
3. Fix long-standing signed-ness issue with "speed" passed around the
   driver from the mac_link_up method.
