The ENAv2 is introducing many new features, mainly the LLQ feature
(Low Latency Queue) which allows the device to process packets faster
and as a result, the latency is noticeably lower.
The second major feature is configurable depth of hw queues where Rx
and Tx can be reconfigured independently and maximum depth of Rx queue
is 8k.
The release also includes many bug fixes and minor new features, like
improved statistics counters and extended statistics.
Driver is still compatible with ENAv1 device.

When wrong req_id is detected some previous mbufs could be used for
receiving different segments of received packets. In such cases chained
mbufs will be twice returned to pool.
To prevent it chained mbuf is now freed just after error detection.
To simplify cleaning, pointers taken for Rx ring are set to NULL.
As after ena_rx_queue_release_bufs and ena_tx_queue_release_bufs queues
are not used updating of next_to_clean pointer is not necessary.

Reset function should return the port to initial state, in which no Tx
and Rx queues are setup. Then application should reconfigure the queues.
According to DPDK documentation the rte_eth_dev_reset() itself is a
generic function which only does some hardware reset operations through
calling dev_unint() and dev_init().
ena_com_dev_reset which perform NIC registers reset should be called
during stop.

The device now allows driver to reconfigure Tx and Rx queues depth
independently. Moreover, maximum size for Tx and Rx can be different.
Those maximum values are received from the device.
After reset, previous ring configuration is restored.
If number of descriptor is set to RTE_ETH_DEV_FALLBACK_RX_RINGSIZE
or RTE_ETH_DEV_FALLBACK_TX_RINGSIZE, the maximum value is restored.
Remove checks, if provided number is not too big, as this is done in
generic functions (rte_eth_rx_queue_setup and rte_eth_tx_queue_setup).
Maximum number of segments is being set for Rx packets and provided to
