2023-01-13net: lan966x: add missing fwnode_handle_put() for ports nodeClément Léger1-5/+8
Since the "ethernet-ports" node is retrieved using device_get_named_child_node(), it should be release after using it. Add missing fwnode_handle_put() and move the code that retrieved the node from device-tree to avoid complicated handling in case of error.

2023-01-09net: lan966x: Allow to add rules in TCAM even if not enabledHoratiu Vultur1-3/+0
The blamed commit implemented the vcap_operations to allow to add an entry in the TCAM. One of the callbacks is to validate the supported keysets. If the TCAM lookup was not enabled, then this will return failure so no entries could be added. This doesn't make much sense, as you can enable at a later point the TCAM. Therefore change it such to allow entries in TCAM even it is not enabled.

2023-01-02net: sparx5: Fix reading of the MAC addressHoratiu Vultur1-1/+1
There is an issue with the checking of the return value of 'of_get_mac_address', which returns 0 on success and negative value on failure. The driver interpretated the result the opposite way. Therefore if there was a MAC address defined in the DT, then the driver was generating a random MAC address otherwise it would use address 0. Fix this by checking correctly the return value of 'of_get_mac_address' Fixes: b74ef9f9cb91 ("net: sparx5: Do not use mac_addr uninitialized in mchp_sparx5_probe()") Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.

2022-12-22net: lan966x: Fix configuration of the PCSHoratiu Vultur1-1/+1
When the PCS was taken out of reset, we were changing by mistake also the speed to 100 Mbit. But in case the link was going down, the link up routine was setting correctly the link speed. If the link was not getting down then the speed was forced to run at 100 even if the speed was something else. On lan966x, to set the speed link to 1G or 2.5G a value of 1 needs to be written in DEV_CLOCK_CFG_LINK_SPEED. This is similar to the procedure in lan966x_port_init. The issue was reproduced using 1000base-x sfp module using the commands: ip link set dev eth2 up ip link addr add 10.97.10.2/24 dev eth2 ethtool -s eth2 speed 1000 autoneg off Fixes: d28d6d2e37d1 ("net: lan966x: add port module support") Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Reviewed-by: Piotr Raczynski <piotr.raczynski@intel.com> Link: https://lore.kernel.org/r/20221221093315.939133-1-horatiu.vultur@microchip.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Currently lan966x, doesn't allow to run PTP over interfaces that are part of the bridge. The reason is when the lan966x was receiving a PTP frame (regardless if L2/IPv4/IPv6) the HW it would flood this frame.

2022-11-30net: microchip: vcap: Change how the rule id is generatedHoratiu Vultur2-7/+1
Currently whenever a new rule id is generated, it picks up the next number bigger than previous id. So it would always be 1, 2, 3, etc. When the rule with id 1 will be deleted and a new rule will be added, it will have the id 4 and not id 1. In theory this can be a problem if at some point a rule will be added and removed ~0 times. Then no more rules can be added because there are no more ids. Change this such that when a new rule is added, search for an empty rule id starting with value of 1 as value 0 is reserved.
