These duplicate includes have been found with scripts/checkincludes.pl but they have been removed manually to avoid removing false positives. Signed-off-by: Pravin Shedge Acked-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: dsa: Fix SWITCHDEV_ATTR_ID_PORT_PARENT_ID

2017-11-11T10:33:10+00:00

SWITCHDEV_ATTR_ID_PORT_PARENT_ID is used by the software bridge when determining which ports to flood a packet out. If the packet originated from a switch, it assumes the switch has already flooded the packet out the switches ports, so the bridge should not flood the packet itself out switch ports. Ports on the same switch are expected to return the same parent ID when SWITCHDEV_ATTR_ID_PORT_PARENT_ID is called. DSA gets this wrong with clusters of switches. As far as the software bridge is concerned, the cluster is all one switch. A packet from any switch in the cluster can be assumed to have been flooded as needed out of all ports of the cluster, not just the switch it originated from. Hence all ports of a cluster should return the same parent. The old implementation did not, each switch in the cluster had its own ID. Also wrong was that the ID was not unique if multiple DSA instances are in operation. Use the tree ID as the parent ID, which is the same for all switches in a cluster and unique across switch clusters.

net: dsa: slave: Handle switchdev host mdb add/del

2017-11-10T04:41:40+00:00

Add code to handle switchdev host mdb add/del. Since DSA uses one of the switch ports as a transport to the host, we just need to add an MDB on this port. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: constify cpu_dp member of dsa_port

2017-11-09T00:26:49+00:00

A DSA port has a dedicated CPU port assigned to it, stored in the cpu_dp member. It is not meant to be modified by a port, thus make it const. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: make tree index unsigned

2017-11-05T13:31:38+00:00

Similarly to a DSA switch and port, rename the tree index from "tree" to "index" and make it an unsigned int because it isn't supposed to be less than 0. u32 is an OF specific data used to retrieve the value and has no need to be propagated up to the tree index.

net: sched: move the can_offload check from binding phase to rule insertion phase

2017-11-02T07:10:39+00:00

This restores the original behaviour before the block callbacks were introduced. Allow the drivers to do binding of block always, no matter if the NETIF_F_HW_TC feature is on or off. Move the check to the block callback which is called for rule insertion. Reported-by: Alexander Duyck Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

net: dsa: remove name arg from slave create

Now that slave dsa_port always have their name set, there is no need to pass it to dsa_slave_create() anymore. Remove this argument. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: Simplify dsa_slave_phy_setup()

Remove the code that tried to identify if a PHY designated by Device Tree required diversion through the DSA-created MDIO bus. This was created mainly for the bcm_sf2.c driver back when it did not have its own MDIO bus driver, which it now has since 461cd1b03e32 ("net: dsa: bcm_sf2: Register our slave MDIO bus").
