net/iavf: initialize large VF setting at startup
lv_enabled is used to remember if large VF setting is configured, but
its value is not initialized at startup. This can lead to a different
configuration regarding the initial configuration of the PF.
For example, a first start is done with 8 rx and 8 tx queues. Large VF
is not needed and reta size is 64.
A second start is done with 20 rx and tx queues. Large VF is required
and reta size is 256.
A third start is done with 2 rx and tx queues. Large VF is not needed
but reta size is 256 as the PF has been configured during the second
start.
In order to have a consistent behavior regarding reta size whatever
the configuration of the PF (may be changed by a previous boot) the
lv_enabled must be set properly at the init phase.

Currently the Tx and Rx ring count for representors is fixed.
It does not consider the number of rings created for the parent

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
rings have been setup. And this can cause representor ring count to be

That assert assured that the amount of bytes requested to be inlined
is greater than or equal to the minimum amount of bytes required
to be inlined. This requirement is either derived from the NIC
inlining mode or configured through devargs. When using TSO this
requirement can be disregarded, because on all NICs it is satisfied by

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.

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.
