   4 Subject: [PATCH] bcm63xx_enet: reset port link state in bcm_enetsw_open
   5
   6 bcm_enetsw_open disables all ports, but does not reset their link state.
   7 This results in connected ports staying disabled after a ifdown/ifup
   8 cycle, since bcm_enetsw_phy_poll only enables them if their current state
   9 is different from the stored link state.
  10
  11 Fix this by also resetting the port link state.
