2022-03-11net: lan966x: Improve the CPU TX bitrate.Horatiu Vultur1-0/+3
When doing manual injection of the frame, it is required to check if the TX FIFO is ready to accept the next word of the frame. For this we are using 'readx_poll_timeout_atomic', the only problem is that before it actually checks the status, is determining the time when to finish polling the status. Which seems to be an expensive operation. Therefore check the status of the TX FIFO before calling 'readx_poll_timeout_atomic'. Doing this will improve the TX bitrate by ~70%. Because 99% the FIFO is ready by that time. The measurements were done using iperf3.

2022-02-25net: switchdev: remove lag_mod_cb from switchdev_handle_fdb_event_to_deviceVladimir Oltean1-5/+7
When the switchdev_handle_fdb_event_to_device() event replication helper was created, my original thought was that FDB events on LAG interfaces should most likely be special-cased, not just replicated towards all switchdev ports beneath that LAG. So this replication helper currently does not recurse through switchdev lower interfaces of LAG bridge ports, but rather calls the lag_mod_cb() if that was provided. No switchdev driver uses this helper for FDB events on LAG interfaces yet, so that was an assumption which was yet to be tested. It is certainly usable for that purpose, as my RFC series shows: https://patchwork.kernel.org/project/netdevbpf/cover/20220210125201.2859463-1-vladimir.oltean@nxp.com/ however this approach is slightly convoluted because: - the switchdev driver gets a "dev" that isn't its own net device, but rather the LAG net device. It must call switchdev_lower_dev_find(dev) in order to get a handle of any of its own net devices (the ones that pass check_cb). - in order for FDB entries on LAG ports to be correctly refcounted per the number of switchdev ports beneath that LAG, we haven't escaped the need to iterate through the LAG's lower interfaces. Except that is now the responsibility of the switchdev driver, because the replication helper just stopped half-way. So, even though yes, FDB events on LAG bridge ports must be special-cased, in the end it's simpler to let switchdev_handle_fdb_* just iterate through the LAG port's switchdev lowers, and let the switchdev driver figure out that those physical ports are under a LAG. The switchdev_handle_fdb_event_to_device() helper takes a "foreign_dev_check" callback so it can figure out whether @dev can autonomously forward to @foreign_dev. DSA fills this method properly: if the LAG is offloaded by another port in the same tree as @dev, then it isn't foreign. If it is a software LAG, it is foreign - forwarding happens in software. Whether an interface is foreign or not decides whether the replication helper will go through the LAG's switchdev lowers or not. Since the lan966x doesn't properly fill this out, FDB events on software LAG uppers will get called. By changing lan966x_foreign_dev_check(), we can suppress them. Whereas DSA will now start receiving FDB events for its offloaded LAG uppers, so we need to return -EOPNOTSUPP, since we currently don't do the right thing for them.

2022-02-09spi: make remove callback a void functionUwe Kleine-König2-6/+2
The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

Phylink will use PCS polling whenever phylink_config.pcs_poll or the phylink_pcs poll member is set. As this driver sets both, remove the former. Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-02-05net: lan966x: Update mdb when enabling/disabling mcast_snoopingHoratiu Vultur3-0/+51
When the multicast snooping is disabled, the mdb entries should be removed from the HW, but they still need to be kept in memory for when the mcast_snooping will be enabled again. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
