I'd get rid of this zeros[] member entirely.  It looks weird and it
causes various "sparse" warnings:

    ../lib/flow.c:595:11: warning: memset with byte count of 0
    ../tests/test-bundle.c:139:15: warning: memset with byte count of 0
    ../tests/test-multipath.c:63:19: warning: memset with byte count of 0

Thanks,

Ben.
