I'm wondering if this stub could be relaxed to just return 0 instead
of triggering error?
As this function is called by virNetDevTapCreateInBridgePort(), it fails
because virNetDevSetCoalesce() fails, making impossible to use the
bridged networking (which is very unfortunate).
The other option could be to ignore virNetDevSetCoalesce() return value
in virNetDevTapCreateInBridgePort() (the only called of this function so
far).
