Out of idle curiosity, I decided to generate disassembly of both
macaddr_cmp_internal(), and the patch's abbreviated comparator. The
former consists of 49 x86-64 instructions at -02 on my machine,
totaling 135 bytes of object code. The latter consists of only 10
instructions, or 24 bytes of object code.
