ethdev: introduce dump API

Added the ethdev dump API which provides querying private info from device.
There exists many private properties in different PMD drivers, such as
adapter state, Rx/Tx func algorithm in hns3 PMD. The information of these
properties is important for debug. As the information is private, the new

net/bnxt: fix ring calculation for representors

Currently the Tx and Rx ring count for representors is fixed.
It does not consider the number of rings created for the parent
function. And that can cause issues not only during initialization
but while running traffic.
Instead check the number of rings created for the parent function
while configuring the ring resources for representors.
In some cases VF rep ring init may happen before the parent function's

configured as 0. In such cases, initialize the VF representor

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
