#
# 2021-03-27: rewrite for CMK 2.0
# 2021-08-21: modified for bgp_peer plugin (from cisco_bgp_peer)
# 2021-08-29: removed htmloutput and infotext_values option
# 2022-04-02: added bgp neighbour states
# 2022-04-29: added upper/lower prefix limit
# 2022-05-09: added discovery rule set
# 2022-05-11: added remote_as to build_item
# 2022-09-05: added internal_item to avoid warnings on cmk updates (THX to Jay2k1 for reporting the issue)
