Re: [libvirt] [PATCH v3 12/36] conf: don't pass interface type into virNetDevBandwidthParse

The virNetDevBandwidthParse method uses the interface type to decide whether to allow use of the "floor" parameter. Using the interface type is not convenient as callers may not have that available, but still wish to allow use of "floor". Switch to an explicit boolean to control its usage. Signed-off-by: Daniel P.
