2022-07-05net: lan966x: hardcode the number of external portsMichael Walle2-6/+3
Instead of counting the child nodes in the device tree, hardcode the number of ports in the driver itself. The counting won't work at all if an ethernet port is marked as disabled, e.g. because it is not connected on the board at all. It turns out that the LAN9662 and LAN9668 use the same switching IP with the same synthesis parameters. The only difference is that the output ports are not connected. Thus, we can just hardcode the number of physical ports to 8.

2022-05-26net: lan966x: check devm_of_phy_get() for -EDEFER_PROBEMichael Walle1-2/+7
At the moment, if devm_of_phy_get() returns an error the serdes simply isn't set. While it is bad to ignore an error in general, there is a particular bug that network isn't working if the serdes driver is compiled as a module. In that case, devm_of_phy_get() returns -EDEFER_PROBE and the error is silently ignored. The serdes is optional, it is not there if the port is using RGMII, in which case devm_of_phy_get() returns -ENODEV. Rearrange the error handling so that -ENODEV will be handled but other error codes will abort the probing.

2022-05-17net: lan966x: Fix assignment of the MAC addressHoratiu Vultur1-0/+28
The following two scenarios were failing for lan966x. 1. If the port had the address X and then trying to assign the same address, then the HW was just removing this address because first it tries to learn new address and then delete the old one. As they are the same the HW remove it. 2. If the port eth0 was assigned the same address as one of the other ports eth1 then when assigning back the address to eth0 then the HW was deleting the address of eth1. The case 1. is fixed by checking if the port has already the same address while case 2. is fixed by checking if the address is used by any other port.

Ethernet frames can be extracted or injected to or from the device's DDR memory. There is one channel for injection and one channel for extraction. Each of these channels contain a linked list of DCBs which contains DB. The DCB contains only 1 DB for both the injection and extraction. Each DB contains a frame. Every time when a frame is received or transmitted an interrupt is generated. It is not possible to use both the FDMA and the manual injection/extraction of the frames. Therefore the FDMA has priority over the manual because of better performance values.

2022-03-25net: sparx5: Refactor mdb handling according to feedbackCasper Andersson5-26/+24
- Remove mact_lookup and use new mact_find instead. - Make pgid_read_mask function. - Set PGID arbiter to start searching at PGID_BASE + 8.

2022-03-21net: sparx5: Add arbiter for managing PGID tableCasper Andersson4-1/+85
The PGID (Port Group ID) table holds port masks for different purposes. The first 72 are reserved for port destination masks, flood masks, and CPU forwarding. The rest are shared between multicast, link aggregation, and virtualization profiles. The GLAG area is reserved to not be used by anything else, since it is a subset of the MCAST area. The arbiter keeps track of which entries are in use. You can ask for a free ID or give back one you are done using. Signed-off-by: Casper Andersson <casper.casan@gmail.com> Signed-off-by: David S.

2022-03-21net: sparx5: Use vid 1 when bridge default vid 0 to avoid collisionCasper Andersson1-3/+23
Standalone ports use vid 0. Let the bridge use vid 1 when "vlan_default_pvid 0" is set to avoid collisions. Since no VLAN is created when default pvid is 0 this is set at "PORT_ATTR_SET" and handled in the Switchdev fdb handler.
