Mark Johnston df40e30c97 netmap: Try to count packet drops in emulated mode
Right now we have little visibility into packet drops within netmap.
Start trying to make packet loss issues more visible by counting queue
drops in the transmit path, and in the input path for interfaces running
in emulated mode, where we place received packets in a bounded software
queue that is processed by rxsync.
