Added the ethdev Rx/Tx desc dump API which provides functions for query
descriptor from device. HW descriptor info differs in different NICs.
The information demonstrates I/O process which is important for debug.
As the information is different between NICs, the new API is introduced.

Adds the framework to support flower representors. The number of VF
representors are parsed from the command line. For physical port
representors the current logic aims to create a representor for
each physical port present on the hardware.
An eth_dev is created for each physical port and VF, and flower
firmware requires a MAC repr cmsg to be transmitted to firmware
with info about the number of physical ports configured.
Reify messages are sent to hardware for each physical port representor.
An rte_ring is also created per representor so that traffic can be
pushed and pulled to this interface.
To up and down the real device represented by a flower representor port
a port mod message is used to convey that info to the firmware. This
message will be used in the dev_ops callbacks of flower representors.
Each cmsg generated by the driver is prepended with a cmsg header.
This commit also adds the logic to fill in the header of cmsgs.
Also add the Rx and Tx path for flower representors. For Rx packets are
dequeued from the representor ring and passed to the eth_dev. For Tx
the first queue of the PF vNIC is used. Metadata about the representor
is added before the packet is sent down to firmware.

VF's command receive queue was mainly used to receive mailbox messages
from PF. There are two type mailbox messages: request response message
and message pushed by PF.
There are two types of threads that can handle these messages:
1) the interrupt thread of the main process: it could handle both types
of messages.
2) other threads: it could only handle request response messages.
The collaboration mechanism between the two type threads is that other
threads set the opcode of processed messages to zero so that the
interrupt thread of the main process does not process these messages
again.
Unfortunately, the other threads mark the message pointed to by the
crq->next-to-use variable which is fixed in the loop, not the message
pointed to by the next-to-use variable.

after the processing is complete, the next-to-use pointer of the
command receive queue should not be updated. Otherwise, some messages
(e.g. messages pushed by PF) maybe discarded.
Unfortunately, the patch to be reverted updates next-to-use pointer of
