Subject: [PATCH] bcm63xx_enet: reset port link state in bcm_enetsw_open

bcm_enetsw_open disables all ports, but does not reset their link state.
This results in connected ports staying disabled after a ifdown/ifup
cycle, since bcm_enetsw_phy_poll only enables them if their current state
is different from the stored link state.

Fix this by also resetting the port link state.
