Description

When adding interfaces to a device or device template, there is already a Syntax in place to have multiple numbered interfaces created with one single step: Eth1/[1-32] for example.

I am managing systems that do not have such a numbered syntax for the network interfaces. For example, I might have to create interfaces e0a, e0b, e0c and e0d.

Currently, this involves 4 clicks on "create and add another", each with selecting the interface type from the list again, which is tedious.

My suggestion is to allow another syntax: e0a,e0b,e0c,e0d to create, in this case, 4 interfaces at the same time.

An alternative would be to allow letters in the brackets as well, which would enable a syntax like e0[a,b,c,d] which would also be fine. Even better, of course, would be e0[a-d] ... But I am fine with any of these options.

If that is not feasible, I would at least like to have the "Create and add another" button to remember all selections in the drop down lists for the next interface, to reduce clicking required. I can open a new case for this if it is necessary.

Mileage may vary based on OS and Browser, however if you're looking for a temp way of doing this -

Hold "ctrl" while clicking create, the creating runs in a new tab, which you can close once completed. Your then left with the original tab, which you can quickly edit and create again etc.

Besides being able to import interface definitions from outside documentation or import previous exports via csv, the ability to add multiple interfaces simultaneously that can't otherwise be easily entered via built-in wildcard is a plus. #1465

I have a working solution almost ready, just need to write tests and documentation, I'll try to get it pushed this week.

@RyanBreaker just curious, which syntax would your solution provide?

[RyanBreaker]

@darkstar It'll be the separated format:

eth[0-3][a-c,f] => eth0a eth0b eth0c eth0f eth1a ... eth3f

Edit:
It'll also support mixing them, for example:

eth[0-3,a-c,f] => eth0 eth1 eth2 eth3 etha ethb ethc ethf

Is there a chance for this Pull Request to be merged?
This would really come in handy!
