[PATCH] net: dsa: mv88e6xxx: egress all frames

[Stefan Eichenberger <eichest@gmail.com>]

Egress multicast and egress unicast is only enabled for CPU/DSA ports
but for switching operation it seems it should be enabled for all ports.
Do I miss something here?

I did the following test:
brctl addbr br0
brctl addif br0 lan0
brctl addif br0 lan1

In this scenario the unicast and multicast packets were not forwarded,
therefore ARP requests were not resolved, and no connection could be
established.

If no bridge is configured we do not forward unicast and multicast
packets because the VLAN mapping is active.
