I've programmed some other switches and the above happens if the port-based
vlan table of
the LAN ports contain the CPU port only.
I currently have no build tree with the ar8216 source code, but on a quick look
into target/linux/generic/files/drivers/net/phy/ar8216.c (svn trunk) at line
458ff:
/* vlan disabled:
* isolate all ports, but connect them to the cpu port */
for (i = 0; i < AR8216_NUM_PORTS; i++) {
if (i == AR8216_PORT_CPU)
continue;
portmask[i] = 1 << AR8216_PORT_CPU;
portmask[AR8216_PORT_CPU] |= (1 << i);
this behaviour seems to be intended if vlan is disabled. Maybe you must enable
vlan?
Or extend portmask[i] to all LAN ports bits set.
Have you already talked to nbd on this issue?

Joerg
