net: dsa: microchip: move switch chip_id detection to ksz_common

2022-06-21T13:26:44+00:00

KSZ87xx and KSZ88xx have chip_id representation at reg location 0. And KSZ9477 compatible switch and LAN937x switch have same chip_id detection at location 0x01 and 0x02. To have the common switch detect functionality for ksz switches, ksz_switch_detect function is introduced. Signed-off-by: Arun Ramadoss Signed-off-by: Paolo Abeni

net: dsa: ksz: added the generic port_stp_state_set function

2022-04-26T08:19:34+00:00

The ksz8795 and ksz9477 uses the same algorithm for the port_stp_state_set function except the register address is different. So moved the algorithm to the ksz_common.c and used the dev_ops for register read and write. This function can also used for the lan937x part. Hence making it generic for all the parts.

net: dsa: microchip: ksz8795: Fix PVID tag insertion

2021-08-10T08:58:14+00:00

ksz8795 has never actually enabled PVID tag insertion, and it also programmed the PVID incorrectly. To fix this: * Allow tag insertion to be controlled per ingress port. On most chips, set bit 2 in Global Control 19. On KSZ88x3 this control flag doesn't exist. * When adding a PVID: - Set the appropriate register bits to enable tag insertion on egress at every other port if this was the packet's ingress port. - Mask *out* the VID from the default tag, before or-ing in the new PVID. * When removing a PVID: - Clear the same control bits to disable tag insertion. - Don't update the default tag. This wasn't doing anything useful. Fixes: e66f840c08a2 ("net: dsa: ksz: Add Microchip KSZ8795 DSA driver") Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller
