dsa: Pass the port to get_sset_count()

2018-03-04T18:34:18+00:00

By passing the port, we allow different ports to have different statistics. This is useful since some ports have SERDES interfaces with their own statistic counters. Signed-off-by: Andrew Lunn Tested-by: Florian Fainelli Reviewed-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: forward timestamping callbacks to switch drivers

2018-02-14T19:33:37+00:00

Forward the rx/tx timestamp machinery from the dsa infrastructure to the switch driver. On the rx side, defer delivery of skbs until we have an rx timestamp. This mimicks the behavior of skb_defer_rx_timestamp. On the tx side, identify PTP packets, clone them, and pass them to the underlying switch driver before we transmit. This mimicks the behavior of skb_tx_timestamp. Adjusted txstamp API to keep the allocation and freeing of the clone in the same central function by Richard Cochran Signed-off-by: Brandon Streiff Signed-off-by: Richard Cochran Signed-off-by: Andrew Lunn Signed-off-by: David S.

net: dsa: forward hardware timestamping ioctls to switch driver

2018-02-14T19:33:37+00:00

This patch adds support to the dsa slave network device so that switch drivers can implement the SIOC[GS]HWTSTAMP ioctls and the ethtool timestamp-info interface. Signed-off-by: Brandon Streiff Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: Allow compiling out legacy support

2017-12-07T19:14:54+00:00

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

2017-12-05T23:01:34+00:00

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

2017-12-03T02:20:59+00:00

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

2017-12-03T02:18:56+00:00

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

2017-12-03T02:18:55+00:00

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

2017-11-13T01:34:54+00:00

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()

2017-11-13T01:34:54+00:00

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
