Two cores can send multi segment packets on two different pcap ports.
Because of this, we can't have one single buffer to linearize packets.
Use rte_pktmbuf_read() to copy the packet into a buffer on the stack
and remove eth_pcap_gather_data() when necessary (if the mbuf is
contiguous, rte_pktmbuf_read() just points at the buffer address).

When a packet cannot be transmitted, the driver is supposed to free this
packet and report it as handled.
This is to prevent the application from retrying to send the same packet
and ending up in a liveloop since the driver will never manage to send
it.

This commit enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring.
For the stingray platform and other platforms needing tighter
control of resource utilization, we retain the ability to
process async events on a receive completion ring.
For Thor-based adapters, we use a dedicated NQ (notification
queue) ring for async events (async events can't currently
be received on a completion ring due to a firmware limitation).
Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.
Allow rxq 0 to be stopped when not being used for async events.
