Its been removed from the default kernel back in April

Log:
  MFC r219775:

    For now remove options FLOWTABLE from the remaining GENERIC kernel
    configurations and make it opt-in for those who want it.  LINT will
    still build it.

    While it may be a perfect win in some scenarios, it still troubles users
    (see PRs) in general cases.  In addition we are still allocating
resources
    even if disabled by sysctl and still leak arp/nd6 entries in case of
    interface destruction.

    Discussed with:	qingli (2010-11-24, just never executed)
    Discussed with:	juli (OCTEON1)
  PR:			kern/148018, kern/155604, kern/144917, kern/146792
