If you look here: [0] & note the description in the docs you referred to before. It should be clear enough the operators is meant to be used only with filter language in functions. """ The filter language supports common integer operators (+,-,*,/), parentheses (a*(b+c)), comparison (a=b, a!=b, a<b, a>=b). Logical operations include unary not (!), and (&&) and or (||). Special operators include (~, !~) for "is (not) element of a set" operation - it can be used on element and set of elements of the same type (returning true if element is contained in the given set), or on two strings (returning true if first string matches a shell-like pattern stored in second string) """ So if you create an function to check if the interface name matches a certain pattern. And in your if() statement matched against true/false return value of function. You should be able to do what you want. Alternatively look at the examples present on the page at [0].
