Support rte_eth_dev_set_mtu for pcap ifaces vdevs by
setting the underlying OS network interface's MTU.
Support is for pcap ifaces only and not for pcap files.
Support is for Linux only.

If you think HW knows "emptiness", and we want to stick to DPDK descriptor
terms.
Can we use the name "avail_thresh?"
When HW sees available descriptors is under this threshold, an event is
triggered.

Previously, anything that prevented the CQs from being drained
would hang the PMD for an unacceptably long time. This commit updates
the drain logic to be resource and time based, thus eliminating
the potential for a long hang when draining the queues in preparation
for a reset.
Fixes: 1857f1922ce
If QID inflights is set to an invalid value it can cause the
PMD to hang. This commit adds checks to make sure that the
value is valid before programming the hardware.

The driver creates a direct MR object of
the HW for each VM memory region,
which maps the VM physical address to
the actual physical address.
Later, after all the MRs are ready,

The configuration threads tasks need a container to
support multiple tasks assigned to a thread in parallel.

The LM process includes a lot of objects creations and

As much as LM time increases, the packet drop of the VM increases.

To speed up queue create time, event qp and cq will create only once.
Each virtq creation will reuse same event qp and cq.
Because FW will set event qp to error state during virtq destroy,

usual. This can save abo

The motivation of this change is to reduce vDPA device queue creation

In VM live migration scenario, this can reduce 0.8ms for each queue

All the threads will be open on the same core of
