Nothing.  It's a question of whether or not use of ALTQ_NOPCC causes
breakage on non-SMP kernels, or if FreeBSD even bothers to support
non-SMP at this point.  "Non-SMP" means "without options SMP".

Rephrased: if SMP is the default, and "options SMP" works just fine on
systems without multiple processors/cores, then the ALTQ_NOPCC option
should probably be removed.
