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?
