The internal buffer pool used for copies of mbufs captured
needs to be thread safe. If capturing on multiple interfaces
or multiple queues, the same pool will be used (consumers).
And if the capture ring gets full, the queues will need
to put back the capture buffer which leads to multiple producers.
