Commit Message

Ben Pfaff May 6, 2021, 5:54 p.m. UTC 
GCC 11 warned that the prototypes and the definitions of these
functions were different: the prototypes used [], the definitions used
[IFNAMSIZ].  This is perfectly valid from a C standards perspective, but
it's confusing and providing sizes gives the compiler and the developer
a useful hint as to usage.  Therefore, this commit adds the expected
sizes.
