Hmm.
Can't say I like the 'global port' notation.
Personally I would prefer to have a sysfs attribute for the local
port number, and have path_id get it from there.
For 95% of all cases the above is just an information duplication
(ie it'll only provide a real value for udev, but not for the user).
So, please, use a sysfs attribute for the local port and keep the
numbering as it is.
Cheers,
Hannes
