Does not show some of the interfaces

I very much like to use this utility but I am sad about the interface limitations. I think it is limited to 7 because if there is more interfaces, they do not show up

I'm running into this as well. If I have the time in the next couple of days I might take a shot at a patch.

Admittedly I know very little about proper defensive coding practices with (n)curses applications, but for my limited use of wanting a quick way to see the tx/rx per interface on more than 7 interfaces, this seems to do the trick.

@websahibi, I know it's been almost three years since you opened this, but FYI :)
