2016-05-25Documentation: networking: dsa: Remove poll_link descriptionFlorian Fainelli1-5/+0
This function has been removed in 4baee937b8d5 ("net: dsa: remove DSA link polling") in favor of using the PHYLIB polling mechanism.

2016-04-08net: dsa: make the STP state function return voidVivien Didelot1-1/+1
The DSA layer doesn't care about the return code of the port_stp_update routine, so make it void in the layer and the DSA drivers. Replace the useless dsa_slave_stp_update function with a dsa_slave_stp_state function used to reply to the switchdev SWITCHDEV_ATTR_ID_PORT_STP_STATE attribute. In the meantime, rename port_stp_update to port_stp_state_set to explicit the state change. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2016-03-14net: dsa: rename port_*_bridge routinesVivien Didelot1-2/+2
Rename DSA port_join_bridge and port_leave_bridge routines to respectively port_bridge_join and port_bridge_leave in order to respect an implicit Port::Bridge namespace.

2016-02-25net: dsa: drop vlan_getnextVivien Didelot1-9/+0
The VLAN GetNext operation is specific to some switches, and thus can be complicated to implement for some drivers. Remove the support for the vlan_getnext/port_pvid_get approach in favor of the generic and simpler port_vlan_dump function.

2016-02-25net: dsa: add port_vlan_dump routineVivien Didelot1-0/+4
Similar to port_fdb_dump, add a port_vlan_dump function to DSA drivers which gets passed the switchdev VLAN object and callback. This function, if implemented, takes precedence over the soon legacy vlan_getnext/port_pvid_get approach. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2016-02-23net: dsa: pass bridge down to driversVivien Didelot1-5/+2
Some DSA drivers may or may not support multiple software bridges on top of an hardware switch. It is more convenient for them to access the bridge's net_device for finer configuration. Removing the need to craft and access a bitmask also simplifies the code. This patch changes the signature of bridge related functions, update DSA drivers, and removes dsa_slave_br_port_mask.
