net: dsa: microchip: add switch offload forwarding support
The flag offload_fwd_mark is set as the switch can forward frames by
itself.
This can be considered a fix to a problem introduced in commit
c2e866911e254067 where the port membership are not set in sync. The flag
offload_fwd_mark just needs to be set in tag_ksz.c to prevent the software
bridge from forwarding duplicate multicast frames.
Fixes: c2e866911e254067 ("microchip: break KSZ9477 DSA driver into two files")
