| Subject | [PATCH net-next v3 1/2] net: dsa: make slave close symmetrical to open |
| Message-ID | <usFf3-3LG-1@gated-at.bofh.it> |
The DSA slave open function configures the unicast MAC addresses on the master device, enable the switch port, change its STP state, then start the PHY device. Make the close function symmetric, by first stopping the PHY device, then changing the STP state, disabling the switch port and restore the master device.
