How igb ports are numbered

[Nomad Esst]

Thanks for your help. I also found if_initname function which is used in igb_setup_interface function (in if_igb.c file). I've found out that the second argument of if_initname function is used to number ports, can I add an offset to it in order to change port numbering? Is it right?
