There is some confusion with the n+m port description. Some 4+1 means
4 lan + 1 wan while in other cases it means 4 user + 1 ext port, even
in Realtek documentation. The last digit in realtek product numbers is
the port number (0 means 10) and it is the sum of user ports and
external ports. From what I investigated, the last digit numbers
normally mean:

3: 2 user + 1 ext port
4: 2 user + 2 ext port
5: 4 user + 1 ext port
6: 5 user + 1 ext port
7: 5 user + 2 ext port
0: 8 user + 2 ext port.

The description in YAML was from the TXT version but it is a good time
to improve it.

BTW, I couldn't find a datasheet for rtl8366rb. The commit message
says it is from a DIR-685 but wikidevi days that device has a
RTL8366SR, which is described as "SINGLE-CHIP 5+1-PORT 10/100/1000
MBPS SWITCH CONTROLLER WITH DUAL MAC INTERFACES".

Do you have any suggestions?
