[pve-devel] [PATCH v2 manager 13/14] api: ceph: mon: fix handling of IPv6 addresses in destroymon

[Fabian Ebner <f.ebner@proxmox.com>]

by also comparing the canonical form to decide when to remove an address. When
getting the IP from the rados information, also drop eventual brackets, so our
existing function can handle it. Add the brackets back within the
remove_addr_from_mon_host function.

New in v2.
