'0x1', '0x2' and '0x3'. Thus, from this perspective these flags are
indistinguishable. To make them distinct, respective bits must be
extracted with a mask and then checked for strict equality.
Specifically here, even if `PKT_TX_UDP_CKSUM` (value '0x3') was set, the
expression `mbuf->ol_flags & PKT_TX_TCP` (the second flag of value
'0x1') is evaluated first and the result is 'true'. In consequence, for
UDP packets the execution flow enters an incorrect branch.

The new API introduced in 18.11 is suggesting, that the driver should
release all it's resources at the dev_close routine.
All resources previously released in uninit routine during PCI removal,
are now being released at the dev_close and the PMD is indicating that
it is supporting API changes by setting RTE_ETH_DEV_CLOSE_REMOVE flag.
As the device is not allocating MAC addresses dynamically, it is setting
mac_addrs field to NULL, so it wouldn't be released by the
rte_eth_dev_release_port().

The driver was passing to the mbuf Rx queue ID instead of hash received
from the device. Now, the RSS hash from the Rx descriptor is being set.

On the start the driver was refilling all Rx buffs, but the old ones
were not released. That way running start/stop for a few times was
causing device to run out of descriptors.
To fix the issue, IO rings are now being destroyed on stop, and
recreated on start. That way the device is not losing any descriptors.
Furthermore, there was also memory leak for the Rx mbufs, which were
created on start and not destroyed on stop.

With the enabling for hotplug on multi-process,
rte_eth_dev_pci_generic_remove can be used to detach the device from
a secondary process also. But we need to take care of the uninit callback
parameter to make sure it handles the secondary case correctly.

As it is a static function, no need to declare before its definition.
