   4 Subject: [PATCH] sfp: provide netdev sfp_bus and use for start/stop
   5
   6 Add a netdev sfp_bus pointer for propagating the phylink start/stop
   7 actions to the SFP cage: the SFP cage may not be directly connected to
   8 phylink, but may be the other side of a fixed PHY, and SFP needs to
   9 know when the netdev is brought up or taken down.
