Hi Wen Gu,
Could we re-phrase this commit message please? I had some trouble
reading it. Maybe something along:
Operations that loopback-ism does not support currently:
- vlan operations, since there is no strong use-case for it
- signal_event operations, since there are no events to be processed
by the loopback-ism device.
Thanks
