I agree that it's not strictly necessary to check flags.mask when port_pre_bridge_flags supports a single flag, but if you did that and structured the code for more future flags, you could avoid that. int ret; if (flags.mask & BR_LEARNING) { ret = qca8k_port_configure_learning(..., flags.val & BR_LEARNING); if (ret) return ret; } return 0; Anyway, probably not a big deal. > } > > int qca8k_port_bridge_join(struct dsa_switch *ds, int port, > diff --git a/drivers/net/dsa/qca/qca8k.h b/drivers/net/dsa/qca/qca8k.h > index c5cc8a172d65..8f88b7db384d 100644 > --- a/drivers/net/dsa/qca/qca8k.h > +++ b/drivers/net/dsa/qca/qca8k.h > @@ -522,6 +522,12 @@ int qca8k_get_mac_eee(struct dsa_switch *ds, int port, struct ethtool_eee *e); > > /* Common bridge function */ > void qca8k_port_stp_state_set(struct dsa_switch *ds, int port, u8 state); > +int qca8k_port_pre_bridge_flags(struct dsa_switch *ds, int port, > + struct switchdev_brport_flags flags, > + struct netlink_ext_ack *extack); > +int qca8k_port_bridge_flags(struct dsa_switch *ds, int port, > + struct switchdev_brport_flags flags, > + struct netlink_ext_ack *extack); > int qca8k_port_bridge_join(struct dsa_switch *ds, int port, > struct dsa_bridge bridge, > bool *tx_fwd_offload, > -- > 2.40.1 >

All handlers of SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS should return -EINVAL for changes made to bridge port flags that aren't supported.

Sorry, on a second look I see that my statement above is incorrect. I do wonder what it was I saw this morning. But this afternoon I see that all users check flags and return -EINVAL as appropriate.

Address learning should initially be turned off by the driver for port operation in standalone mode, then the DSA core handles changes to it via ds->ops->port_bridge_flags(). Currently this is not the case for qca8k where learning is enabled unconditionally in qca8k_setup for every user port. Handle ports configured in standalone mode by making the learning configurable and not enabling it by default. Implement .port_pre_bridge_flags and .port_bridge_flags dsa ops to enable learning for bridge that request it and tweak .port_stp_state_set to correctly disable learning when port is configured in standalone mode.
