Why does this particular PMD need spinlocks when doing RX and TX, while other device types do not? How is adding/removing devices from a bonded device different to other control operations that can be done on physical PMDs? Is this not similar to say bringing down or hotplugging out a physical port just before an RX or TX operation takes place? For all other PMDs we rely on the app to synchronise control and data plane operation - why not here? /Bruce
