I think you are right on this one. There's one user who investigated
some PPPoE/broadcast issue with the WAN port and here's what he found
out: [0]
Here's where the initialization takes place in the OpenWrt driver: [1]
To sum up "ased's" findings, the original driver (at least in some of
the ifxmips_ppa_datapath_vr9_* configurations):
- PCE_PMAP1 is set to 0x40 (= port 7 / CPU port) instead of 0x7f (= all ports)
- PCE_PMAP2 and 3 are set to 0x7f & (~priv->hw->wan_map) ("all but the
configured WAN port(s)")
I don't have access to the datasheets, so I cannot say what
"monitoring" means exactly (PCE_PMAP1).
Unfortunately I did not have time to play around with it yet, so I
can't tell you much more.
But maybe someone with access to the datasheets can at least confirm
this and explain the PCE_PMAP1 register.

Martin
