LinuxCNC crashes on exit when component `litexcnc_eth` is used about litex-cnc HOT 11 CLOSED

litexcnc: ERROR: Direct usage of the module `litexcnc_eth` is not supported
litexcnc: This is caused by the following loadrt-commands in your HAL-file:
litexcnc:     loadrt litexcnc
litexcnc:     loadrt litexcnc_eth connection_string="10.0.0.10"
litexcnc: Please use the folllowing single command in your hal-file instead:
litexcnc:     loadrt litexcnc connections="eth:10.0.0.10"
