net: dsa: felix: support FDB entries on offloaded LAG interfaces
This adds the logic in the Felix DSA driver and Ocelot switch library. For Ocelot switches, the DEST_IDX that is the output of the MAC table lookup is a logical port (equal to physical port, if no LAG is used, or a dynamically allocated number otherwise). The allocation we have in place for LAG IDs is different from DSA's, so we can't use that: - DSA allocates a continuous range of LAG IDs starting from 1 - Ocelot appears to require that physical ports and LAG IDs are in the same space of [0, num_phys_ports), and additionally, ports that aren't in a LAG must have physical port id == logical port id The implication is that an FDB entry towards a LAG might need to be deleted and reinstalled when the LAG ID changes.
