net: dsa: Allow compiling out legacy support

2017-12-07T19:14:54Z

Introduce a configuration option: CONFIG_NET_DSA_LEGACY allowing to compile out support for the old platform device and Device Tree binding registration. Support for these configurations is scheduled to be removed in 4.17. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: return per-port upstream port

2017-12-05T23:01:34Z

The current dsa_upstream_port() helper still assumes a unique CPU port in the whole switch fabric. This is becoming wrong, as every port in the fabric has its dedicated CPU port, thus every port has an upstream port. Add a port argument to the dsa_upstream_port() helper and fetch its CPU port instead of the deprecated unique fabric CPU port. A CPU or unused port has no dedicated CPU port, so return itself in this case. At the same time, change the return value from u8 to unsigned int since there is no need to limit the size here.

net: dsa: introduce dsa_towards_port helper

2017-12-03T02:20:59Z

Add a new helper returning the local port used to reach an arbitrary switch port in the fabric. Its only user at the moment is the dsa_upstream_port helper, which returns the local port reaching the dedicated CPU port, but it will be used in cross-chip FDB operations.

net: dsa: remove trans argument from mdb ops

2017-12-03T02:18:56Z

The DSA switch MDB ops pass the switchdev_trans structure down to the drivers, but no one is using them and they aren't supposed to anyway. Remove the trans argument from MDB prepare and add operations. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: remove trans argument from vlan ops

2017-12-03T02:18:55Z

The DSA switch VLAN ops pass the switchdev_trans structure down to the drivers, but no one is using them and they aren't supposed to anyway. Remove the trans argument from VLAN prepare and add operations. At the same time, fix the following checkpatch warning: WARNING: line over 80 characters #74: FILE: drivers/net/dsa/dsa_loop.c:177: + const struct switchdev_obj_port_vlan *vlan) Signed-off-by: Vivien Didelot Signed-off-by: David S.

net: dsa: Support prepended Broadcom tag

2017-11-13T01:34:54Z

Add a new type: DSA_TAG_PROTO_PREPEND which allows us to support for the 4-bytes Broadcom tag that we already support, but in a format where it is pre-pended to the packet instead of located between the MAC SA and the Ethertyper (DSA_TAG_PROTO_BRCM).

net: dsa: Pass a port to get_tag_protocol()

2017-11-13T01:34:54Z

A number of drivers want to check whether the configured CPU port is a possible configuration for enabling tagging, pass down the CPU port number so they verify that. Signed-off-by: Florian Fainelli Reviewed-by: Vivien Didelot Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: setup and teardown tree

2017-11-09T00:26:49Z

This commit provides better scope for the DSA tree setup and teardown functions. It renames the "applied" bool to "setup" and print a message when the tree is setup, as it is done during teardown. At the same time, check dst->setup in dsa_tree_setup, where it is set to true. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: constify cpu_dp member of dsa_port

2017-11-09T00:26:49Z

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

2017-11-05T13:31:38Z

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.
