net: dsa: read mac address from DT for slave device

2020-11-10T11:36:02+00:00

commit a2c7023f7075ca9b80f944d3f20f60e6574538e2 upstream. Before creating a slave netdevice, get the mac address from DTS and apply in case it is valid. Signed-off-by: Xiaofei Shen Signed-off-by: Vinod Koul Signed-off-by: David S. Miller Cc: Pali Rohár Signed-off-by: Greg Kroah-Hartman

net: dsa: Remove VLA usage

2018-07-18T22:08:31+00:00

We avoid 2 VLAs by using a pre-allocated field in dsa_switch. We also try to avoid dynamic allocation whenever possible (when using fewer than bits-per-long ports, which is the common case).

net: dsa: Plug in PHYLINK support

2018-05-11T16:03:06+00:00

Add support for PHYLINK within the DSA subsystem in order to support more complex devices such as pluggable (SFP) and non-pluggable (SFF) modules, 10G PHYs, and traditional PHYs. Using PHYLINK allows us to drop some amount of complexity we had while probing fixed and non-fixed PHYs using Device Tree. Because PHYLINK separates the Ethernet MAC/port configuration into different stages, we let switch drivers implement those, and for now, we maintain functionality by calling dsa_slave_adjust_link() during phylink_mac_link_{up,down} which provides semantically equivalent steps. Drivers willing to take advantage of PHYLINK should implement the phylink_mac_* operations that DSA wraps. We cannot quite remove the adjust_link() callback just yet, because a number of drivers rely on that for configuring their "CPU" and "DSA" ports, this is done dsa_port_setup_phy_of() and dsa_port_fixed_link_register_of() still. Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2) will need to implement phylink_mac_ops from now on to preserve functionality, since PHYLINK *does not* create a phy_device instance for fixed links.

net: dsa: Add PHYLINK switch operations

2018-05-11T16:03:05+00:00

In preparation for adding support for PHYLINK within DSA, define a number of operations that we will need and that switch drivers can start implementing. Proper integration with PHYLINK will follow in subsequent patches. We start selecting PHYLINK (which implies PHYLIB) in net/dsa/Kconfig such that drivers can be guaranteed that this dependency is properly taken care of and can start referencing PHYLINK helper functions without requiring stubs or anything.

net: dsa: Allow providing PHY statistics from CPU port

2018-04-27T15:53:03+00:00

Implement the same type of ethtool diversion that we have for ETH_SS_STATS and make it work with ETH_SS_PHY_STATS. This allows providing PHY level statistics for CPU ports that are directly connecting to a PHY device. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: Pass stringset to ethtool operations

2018-04-27T15:53:03+00:00

Up until now we largely assumed that we were interested in ETH_SS_STATS type of strings for all ethtool operations, this is about to change with the introduction of additional string sets, e.g: ETH_SS_PHY_STATS. Update all functions to take an appropriate stringset argument and act on it when it is different than ETH_SS_STATS for now. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

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
