-Port name formatting
-####################
-
-Some node like qemu allow you to personnalize the name of ports in order to match the name of the interfaces inside the emulator.
-
-Simple syntax
-==============
-The first {} will be replace by the interface number 
-
-For example: "eth{}" will give:
-* eth0
-* eth1
-* eth2
-
-Or more verbose "eth{port0}" and "eth{0}" will do the same.
-
-Use segments
-============
-
-Segment allow you to split your interface in multiple ports 
-
-For example "Ethernet{segment0}/{port0}" with a segment size of 3:
-
-- Ethernet0/0
-- Ethernet0/1
-- Ethernet0/2
-- Ethernet1/0
-- Ethernet1/1
-
-You can also change the start number.
-
-For example "Ethernet{segment1}/{port1}" with a segment size of 3:
-
-- Ethernet1/1
-- Ethernet1/2
-- Ethernet1/3
-- Ethernet2/1
-- Ethernet2/2
-
-This work from port0 to port9 if you need a bigger range ask us.
