net: dsa: Do not suspend/resume closed slave_dev

2018-08-06T14:18:19+00:00

[ Upstream commit a94c689e6c9e72e722f28339e12dff191ee5a265 ] If a DSA slave network device was previously disabled, there is no need to suspend or resume it.

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

act_mirred: get rid of tcfm_ifindex from struct tcf_mirred

2017-12-06T19:50:13+00:00

tcfm_dev always points to the correct netdev and we already hold a refcnt, so no need to use tcfm_ifindex to lookup again. If we would support moving target netdev across netns, using pointer would be better than ifindex. This also fixes dumping obsolete ifindex, now after the target device is gone we just dump 0 as ifindex.

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
