* net: dsa: remove tag_protocol from dsa_switchVivien Didelot2016-04-211-5/+0

| | | | | | | | | | | | The phys in phys_port_mask suggests this mask is about PHYs. In fact, it means physical ports. Rename to enabled_port_mask, indicating external enabled ports of the switch, which is hopefully less confusing.

* net: dsa: make the VLAN add function return voidVivien Didelot2016-04-081-1/+1
| | | | | | | | | | | | | | | | The switchdev design implies that a software error should not happen in the commit phase since it must have been previously reported in the prepare phase. If an hardware error occurs during the commit phase, there is nothing switchdev can do about it. The DSA layer separates port_vlan_prepare and port_vlan_add for simplicity and convenience. If an hardware error occurs during the commit phase, there is no need to report it outside the driver itself. Make the DSA port_vlan_add routine return void for explicitness.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support bridging offloads in DSA switch drivers, select NET_SWITCHDEV to get access to the port_stp_update and parent_get_id NDOs that we are required to implement. To facilitate the integratation at the DSA driver level, we implement 3 types of operations: - port_join_bridge - port_leave_bridge - port_stp_update DSA will resolve which switch ports that are currently bridge port members as some Switch hardware/drivers need to know about that to limit the register programming to just the relevant registers (especially for slow MDIO buses). We also take care of setting the correct STP state when slave network devices are brought up/down while being bridge members. Finally, when a port is leaving the bridge, we make sure we set in BR_STATE_FORWARDING state, otherwise the bridge layer would leave it disabled as a result of having left the bridge.

| | | | | | | | | | | | | | | | | | | | | | | | This change addresses several issues. First, it was possible to set tag_protocol without setting the ops pointer. To correct that I have reordered things so that rcv is now populated before we set tag_protocol. Second, it didn't make much sense to keep setting the device ops each time a new slave was registered. So by moving the receive portion out into root switch initialization that issue should be addressed. Third, I wanted to avoid sending tags if the rcv pointer was not registered so I changed the tag check to verify if the rcv function pointer is set on the root tree. If it is then we start sending DSA tagged frames. Finally I split the device ops pointer in the structures into two spots. I placed the rcv function pointer in the root switch since this makes it easiest to access from there, and I placed the xmit function pointer in the slave for the same reason.

Under certain configurations, the physical port mask might not be a 1:1 mapping to the MII PHYs mask. This is the case, if e.g: Port 1 of the switch is used and connects to a PHY at a MDIO address different than 1. Introduce a phys_mii_mask variable which allows driver to implement and divert their own MDIO read/writes operations for a subset of the MDIO PHY addresses.
