ethdev: introduce flow engine configuration

The flow rules creation/destruction at a large scale incurs a performance
penalty and may negatively impact the packet processing when used
as part of the datapath logic. This is mainly because software/hardware
resources are allocated and prepared during the flow rule creation.

In order to optimize the insertion rate, PMD may use some hints provided
by the application at the initialization phase. The rte_flow_configure()
function allows to pre-allocate all the needed resources beforehand.
These resources can be used at a later stage without costly allocations.
Every PMD may use only the subset of hints and ignore unused ones or
fail in case the requested configuration is not supported.

The rte_flow_info_get() is available to retrieve the information about
supported pre-configurable resources. Both these functions must be called
before any other usage of the flow API engine.

ethdev: add mbuf dynfield for incomplete IP reassembly

Hardware IP reassembly may be incomplete for multiple reasons like
reassembly timeout reached, duplicate fragments, etc.
To save application cycles to process these packets again, a new
mbuf dynflag is added to show that the mbuf received is not
reassembled properly.

Now if this dynflag is set, application can retrieve corresponding
chain of mbufs using mbuf dynfield set by the PMD. Now, it will be
up to application to either drop those fragments or wait for more time.

ethdev: introduce IP reassembly offload

IP Reassembly is a costly operation if it is done in software.
The operation becomes even more costlier if IP fragments are encrypted.
However, if it is offloaded to HW, it can considerably save application
cycles.

Hence, a new offload feature is exposed in eth_dev ops for devices which
can attempt IP reassembly of packets in hardware.
- rte_eth_ip_reassembly_capability_get() - to get the maximum values
of reassembly configuration which can be set.
- rte_eth_ip_reassembly_conf_set() - to set IP reassembly configuration
and to enable the feature in the PMD (to be called before
rte_eth_dev_start()).
- rte_eth_ip_reassembly_conf_get() - to get the current configuration
set in PMD.

Now when the offload is enabled using rte_eth_ip_reassembly_conf_set(),
the resulting reassembled IP packet would be a typical segmented mbuf in
case of success.

And if reassembly of IP fragments is failed or is incomplete (if
fragments do not come before the reass_timeout, overlap, etc), the mbuf
dynamic flags can be updated by the PMD. This is updated in a subsequent
patch.

ethdev: support queue-based priority flow control

Based on device support and use-case need, there are two different ways
to enable PFC. The first case is the port level PFC configuration, in
this case, rte_eth_dev_priority_flow_ctrl_set() API shall be used to
configure the PFC, and PFC frames will be generated using based on VLAN
TC value.

The second case is the queue level PFC configuration, in this
case, Any packet field content can be used to steer the packet to the
specific queue using rte_flow or RSS and then use
rte_eth_dev_priority_flow_ctrl_queue_configure() to configure the
TC mapping on each queue.
Based on congestion selected on the specific queue, configured TC
shall be used to generate PFC frames.

ethdev: fix representor port ID search by name

The patch is required for all PMDs which do not provide representors
info on the representor itself.

The function, rte_eth_representor_id_get(), is used in
eth_representor_cmp() which is required in ethdev class iterator to
search ethdev port ID by name (representor case). Before the patch
the function is called on the representor itself and tries to get
representors info to match.

Search of port ID by name is used after hotplug to find out port ID
of the just plugged device.

Getting a list of representors from a representor does not make sense.
Instead, a backer device should be used.

To this end, extend the rte_eth_dev_data structure to include the port ID
of the backing device for representors.
