New Revision: 332772
URL: https://svnweb.freebsd.org/changeset/base/332772

Log:
  Fix ipfw table creation when net.inet.ip.fw.tables_sets = 0 and non zero set
  specified on table creation. This fixes following:
  
  # sysctl net.inet.ip.fw.tables_sets
  net.inet.ip.fw.tables_sets: 0
  # ipfw table all info
  # ipfw set 1 table 1 create type addr
  # ipfw set 1 table 1 create type addr
  # ipfw add 10 set 1 count ip from table\(1\) to any
  00010 count ip from table(1) to any
  # ipfw add 10 set 1 count ip from table\(1\) to any
  00010 count ip from table(1) to any
  # ipfw table all info
