" ERROR: Macros with multiple statements should be enclosed in a do -
while loop"
Reported by checkpath.
do loop with the conditional expression set to a constant
value of zero (0).This creates a loop that
will execute exactly one time.This is a coding idiom that
allows a multi-line macro to be used anywhere
that a single statement can be used.
So, enclose `gb_loopback_stats_attrs` macro in do - while (0) to
fix checkpath error
