| 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. |
