Currently the port based VLAN maps should be configured to allow every
port to egress frames on all other ports, except themselves.
The debugfs interface shows that they are misconfigured. For instance, a
7-port switch has the following content in the related register 0x06:
GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6
...
6: 1fa4 1f0f 4 7f 7e 7d 7c 7b 7a 79
...
This means that port 3 is allowed to talk to port 2-6, but cannot talk
to ports 0 and 1. With this fix, port 3 can correctly talk to all ports
except 3 itself:
GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6
...
6: 1fa4 1f0f 4 7e 7d 7b 77 6f 5f 3f
...
