#
# @summary a defined resource that can match for ipsets at the top of a chain. This is a per-chain resource. You cannot mix IPv4 and IPv6 sets.
#
# @see http://ferm.foo-projects.org/download/2.1/ferm.html#set
#
# @example
# ferm::ipset { 'CONSUL':
# sets => {
# 'internet' => 'ACCEPT'
# },
# }
#
# @example create to matches for IPv6, both at the end of the `INPUT` chain. Explicitly mention the `filter` table.
# ferm::ipset { 'INPUT':
# prepend_to_chain => false,
# table => 'filter',
# ip_version => 'ip6',
# sets => {
# 'testset01' => 'ACCEPT',
# 'anothertestset' => 'DROP'
# },
# }
#
# @param chain
# name of the chain we want to apply those rules to. The name of the defined resource will be used as default value for this.
#
# @param table
# name of the table where we want to apply this. Defaults to `filter` because that's the most common usecase.
#
# @param ip_version
# sadly, ip sets are version specific. You cannot mix IPv4 and IPv6 addresses. Because of this you need to provide the version.
#
# @param sets
# A hash with multiple sets. For each hash you can provide an action like `DROP` or `ACCEPT`.
#

Hash[String[1], Ferm::Actions] $sets,
