This patch creates the framework to define the DPDK PCI functional
device by specifying the pci attributes like Vendor ID, Device ID,
Sub Vendor ID, Sub Device ID and Class.This enables a flexible way to
add DPDK function devices based on PCI attributes.
Crypto devices can belong to Encryption class(0x10) or Processor
class(0x0b) based on the vendor preference.
Using this framework, The above disparity can be encoded in the following
format
encryption_class = [{'Class': '10', 'Vendor': None,

* the type for managing cpu sets is cpuset_t on FreeBSD rather than

doc: add description for modified xstats API
Documentation change for modified extended statistics API functions.
The old API only allows retrieval of *all* of the NIC statistics
at once. Given this requires a MMIO read PCI transaction per statistic
it is an inefficient way of retrieving just a few key statistics.
Often a monitoring agent only has an interest in a few key statistics,
and the old API forces wasting CPU time and PCIe bandwidth in retrieving
*all* statistics; even those that the application didn't explicitly
show an interest in.
The new, more flexible API allow retrieval of statistics per ID.
If a PMD wishes, it can be implemented to read just the required
NIC registers. As a result, the monitoring application no longer wastes
PCIe bandwidth and CPU time.

For zero copy mode, we need pin the mbuf to not let the underlaying PMD
driver (or the app) free the mbuf. Currently, only the heading mbuf is
pinned. However, the mbuf free function would try to free all mbufs
in the mbuf chain (-1 to the refcnt). This may lead the head mbuf being
still pinned, while the other subsequent mbufs are actually freed. Which
is wrong.
It becomes more fatal after the mbuf refactor, more specificly, after
the commit
8f094a9ac5d7 ("mbuf: set mbuf fields while in pool"). The
refcnt resets to 1 after the last real reference. OTOH, it leads to a
situtation that we never know one mbuf is actually freed or not. This
would result the mbuf __just__ after the heading mbuf being freed twice:
it's firstly freed (and put back to mempool) when the underlaying PMD
finishes the DMA. Later, it will then be freed again when vhost unpins
it. Meaning, one mbuf may be returned to the mempool twice, while in
turn, being allocated twice later. Something uncertain may happen then.
For example, the VM2VM case becomes broken.

net/virtio: support to turn on/off traffic flow
Current virtio_dev_stop only disables interrupt and marks link down,
When it is invoked, tx/rx traffic flows still work. This is a strange
behavior. The patch supports the switch of flow.
