      .The `maddress` option of the `ip monitor` command fails

      A previous update added the `ip monitor maddress` command to the `iproute2` package. Due to a bug, the `ip monitor` command now fails on RHEL with the following error:

      ----
      Failed to add ipv4 mcaddr group to list
      ----

      To work around the problem, use a specific `ip monitor` subcommand, and avoid the `maddress` option.
