2024-08-16net: dsa: microchip: add WoL support for KSZ87xx familyPieter Van Trappen
Add WoL support for KSZ87xx family of switches. This code was tested with a KSZ8794 chip. Implement ksz_common usage of the new device-tree property 'microchip,pme-active-high'. Make use of the now generalized ksz_common WoL functions, adding an additional interrupt register write for KSZ87xx. Add helper functions to convert from PME (port) read/writes to indirect register read/writes in the dedicated ksz8795 sources. Add initial configuration during (port) setup as per KSZ9477.

2024-05-08net: dsa: microchip: dcb: add special handling for KSZ88X3 familyOleksij Rempel
KSZ88X3 switches have different behavior on different ports: - It seems to be not possible to disable VLAN PCP classification on port 2. It means, as soon as mutliqueue support is enabled, frames with VLAN tag will get PCP prios. This behavior do not affect Port 1 - it is possible to disable PCP prios. - DSCP classification is not working on Port 2. Since there are still usable configuration combinations, I added some quirks to make sure user will get appropriate error message if not possible configuration is chosen.

Additionally, flow control was hardcoded and only functional in duplex mode. This update enhances the configurability of these parameters.

2022-12-07net: dsa: microchip: ksz8: add MTU configuration supportOleksij Rempel
Make MTU configurable on KSZ87xx and KSZ88xx series of switches. Before this patch, pre-configured behavior was different on different switch series, due to opposite meaning of the same bit: - KSZ87xx: Reg 4, Bit 1 - if 1, max frame size is 1532; if 0 - 1514 - KSZ88xx: Reg 4, Bit 1 - if 1, max frame size is 1514; if 0 - 1532 Since the code was telling "... SW_LEGAL_PACKET_DISABLE, true)", I assume, the idea was to set max frame size to 1532. With this patch, by setting MTU size 1500, both switch series will be configured to the 1532 frame limit. This patch was tested on KSZ8873.
