2022-02-05net: lan966x: Implement the callback SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLEDHoratiu Vultur4-1/+110
The callback allows to enable/disable multicast snooping. When the snooping is enabled, all IGMP and MLD frames are redirected to the CPU, therefore make sure not to set the skb flag 'offload_fwd_mark'. The HW will not flood multicast ipv4/ipv6 data frames. When the snooping is disabled, the HW will flood IGMP, MLD and multicast ipv4/ipv6 frames according to the mcast_flood flag. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-02-05net: lan966x: Update the PGID used by IPV6 data framesHoratiu Vultur1-1/+5
When enabling the multicast snooping, the forwarding of the IPV6 frames has it's own forwarding mask. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-02-03net: lan966x: use .mac_select_pcs() interfaceHoratiu Vultur2-1/+9
Convert lan966x to use the mac_select_interface instead of phylink_set_pcs. Signed-off-by: Horatiu Vultur <[email protected]> Reviewed-by: Russell King (Oracle) <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
2022-02-01net: lan966x: Implement get_ts_infoHoratiu Vultur1-0/+34
Implement the function get_ts_info in ethtool_ops which is needed to get the HW capabilities for timestamping. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-02-01net: lan966x: Add support for ptp interruptsHoratiu Vultur3-0/+130
When doing 2-step timestamping the HW will generate an interrupt when it managed to timestamp a frame. It is the SW responsibility to read it from the FIFO. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-02-01net: lan966x: Update extraction/injection for timestampingHoratiu Vultur3-5/+207
Update both the extraction and injection to do timestamping of the frames. The extraction is always doing the timestamping while for injection is doing the timestamping only if it is configured. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-02-01net: lan966x: Implement SIOCSHWTSTAMP and SIOCGHWTSTAMPHoratiu Vultur3-0/+100
Implement the ioctl callbacks SIOCSHWTSTAMP and SIOCGHWTSTAMP to allow to configure the ports to enable/disable timestamping for TX. The RX timestamping is always enabled. The HW is capable to run both 1-step timestamping and 2-step timestamping. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-02-01net: lan966x: Add support for ptp clocksHoratiu Vultur4-1/+317
The lan966x has 3 PHC. Enable each of them, for now all the timestamping is happening on the first PHC. Acked-by: Richard Cochran <[email protected]> Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2022-01-26net: lan966x: Fix sleep in atomic context when updating MAC tableHoratiu Vultur1-5/+6
The function lan966x_mac_wait_for_completion is used to poll the status of the MAC table using the function readx_poll_timeout. The problem with this function is that is called also from atomic context. Therefore update the function to use readx_poll_timeout_atomic.

2022-01-26net: lan966x: Fix sleep in atomic context when injecting framesHoratiu Vultur1-3/+3
On lan966x, when injecting a frame it was polling the register QS_INJ_STATUS to see if it can continue with the injection of the frame. The problem was that it was using readx_poll_timeout which could sleep in atomic context. This patch fixes this issue by using readx_poll_timeout_atomic.

2022-01-05net: lan966x: Extend switchdev with mdb supportHoratiu Vultur6-2/+536
Extend lan966x driver with mdb support by implementing the switchdev calls: SWITCHDEV_OBJ_ID_PORT_MDB and SWITCHDEV_OBJ_ID_HOST_MDB. It is allowed to add both ipv4/ipv6 entries and l2 entries. To add ipv4/ipv6 entries is not required to use the PGID table while for l2 entries it is required. The PGID table is much smaller than MAC table so only fewer l2 entries can be added.

2022-01-05net: lan966x: Add PGID_GP_START and PGID_GP_ENDHoratiu Vultur1-2/+6
The first entries in the PGID table are used by the front ports while the last entries are used for different purposes like flooding mask, copy to CPU, etc. So add these macros to define which entries can be used for general purpose.

2022-01-05net: lan966x: Add function lan966x_mac_ip_learn()Horatiu Vultur3-5/+42
Extend mac functionality with the function lan966x_mac_ip_learn. This function adds an entry in the MAC table for IP multicast addresses. These entries can copy a frame to the CPU but also can forward on the front ports. This functionality is needed for mdb support. In case the CPU and some of the front ports subscribe to an IP multicast address. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2021-12-27net: lan966x: Fix the vlan used by host portsHoratiu Vultur1-3/+3
The blamed commit changed the vlan used by the host ports to be 4095 instead of 0. Because of this change the following issues are seen: - when the port is probed first it was adding an entry in the MAC table with the wrong vlan (port->pvid which is default 0) and not HOST_PVID - when the port is removed from a bridge, it was using the wrong vlan to add entries in the MAC table. It was using the old PVID and not the HOST_PVID This patch fixes this two issues by using the HOST_PVID instead of port->pvid. Fixes: 6d2c186afa5d5d ("net: lan966x: Add vlan support.")

2021-12-20net: lan966x: Add support to offload the forwarding.Horatiu Vultur5-2/+354
This patch adds basic support to offload in the HW the forwarding of the frames. The driver registers to the switchdev callbacks and implements the callbacks for attributes SWITCHDEV_ATTR_ID_PORT_STP_STATE and SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME. It is not allowed to add a lan966x port to a bridge that contains a different interface than lan966x. Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2021-12-20net: lan966x: Remove .ndo_change_rx_flagsHoratiu Vultur1-23/+0
The function lan966x_port_change_rx_flags() was used only when IFF_PROMISC flag was set. In that case it was setting to copy all the frames to the CPU instead of removing any RX filters. Therefore remove it. Fixes: d28d6d2e37d10d ("net: lan966x: add port module support") Signed-off-by: Horatiu Vultur <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2021-12-20net: lan966x: More MAC table functionalityHoratiu Vultur2-0/+114

2021-12-20net: lan966x: add support for interrupts from analyzerHoratiu Vultur3-0/+266
This patch adds support for handling the interrupts generated by the analyzer. Currently, only the MAC table generates these interrupts. The MAC table will generate an interrupt whenever it learns or forgets an entry in the table. It is the SW responsibility figure out which entries were added/removed.

2021-12-13net: lan966x: Fix the configuration of the pcsHoratiu Vultur1-6/+0
When inserting a SFP that runs at 2.5G, then the Serdes was still configured to run at 1G. Because the config->speed was 0, and then the speed of the serdes was not configured at all, it was using the default value which is 1G. This patch stop calling the serdes function set_speed and allow the serdes to figure out the speed based on the interface type.

The lan966x is using the function 'packing' to create/extract the information for the IFH, that is used to be added in front of the frames when they are injected/extracted. Therefore update the Kconfig to select config option 'PACKING' whenever lan966x driver is enabled.
