Author: kmacy

New Revision: 196388
URL: http://svn.freebsd.org/changeset/base/196388

Log:
  This change fixes a comment and addresses a complaint by kib@ by
  moving a frequently executed flowtable syslog statement from being
  conditional on bootverbose to conditional on a per-vnet flowtable
  sysctl.
