Use a u16 for fdb flags for future use, so that other flags can also be sent the same way without having to change function interfaces. If we have unsupported flags in the new flags, we do not do unnecessary work and so we return at once. This ensures that the drivers are not called with unsupported flags, so that the drivers do not need to check the new flags. As the dynamic flag is a legacy flag, all drivers support it by default at least as they have done hitherto. Ensure that the dynamic FDB flag is only set when added from userspace, as the feature it supports is to be handled from userspace. Signed-off-by: Hans J.

In the mv88e6xxx offloaded case, we can use the HoldAt1 feature, that gives an age out interrupt when the FDB entry is about to age out, so that userspace can be notified of the entry being deleted with the help of an SWITCHDEV_FDB_DEL_TO_BRIDGE event. When adding a dynamic entry the bridge must be informed that the driver takes care of the ageing be sending an SWITCHDEV_FDB_OFFLOADED event, telling the bridge that this added FDB entry will be handled by the driver. With this implementation, trace events for age out interrupts are also added. note: A special case arises with the age out interrupt, as the entry state/spid (source port id) value read from the registers will be zero. Thus we need to extract the source port from the port vector instead. Signed-off-by: Hans J.

Beware, DSA might not accept the ageing time you want. Check the age_time_coeff value for your driver. Signed-off-by: Hans J.
