40e7c02155 net/ena: fix L4 checksum Tx offload
During an if-condition evaluation, a 2-bit flag evaluates to 'true' for
'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.

4217cb0b7d net/ena: fix assigning NUMA node to IO queue
Previous solution was using memzones in invalid way in hope to assign
IO queue to the appropriate NUMA zone.

The right way is to use socket_id from the rx/tx queue setup function
and then pass it to the IO queue.

117ba4a604 net/ena: get device info statically
Whenever the app is calling rte_eth_dev_info_get(), it shouldn't use the
admin command. It was causing problems, if it was called from the
secondary process - the main process was crashing, and the secondary app
wasn't getting any result, as the admin request couldn't be processed by
the process which was requesting the data.

To fix that, the data is being written to the adapter structure during
device initialization routine.

is 8k.

The release also includes many bug fixes and minor new features, like

This patch updates it to version from 2018.09.26.

It adds support for ENAv2 device together with LLQ feature, adds
doorbell optimization and reconfiguration of HW queues depth
independently.

The driver was adjusted to the new changes in the HAL.

d6db681bf9 drivers/net: fix several Tx prepare functions
Since below commit, several tx_prep functions are broken, they fail to
pass supported Tx offload features check:
PKT_TX_IPVx must be set when any PKT_TX_L4 checksum is requested,
but these values are not present in the mask of supported Tx offloads
of several drivers that advertise PKT_TX_L4_MASK.
So any packet sent to those drivers with a L4 checksum request and
one of PKT_TX_IPVx bit set is rejected by the tx prepare function.

79405ee175 net/ena: fix out of order completion
rx_buffer_info should be refill not linearly, but out of order.
IDs should be taken from empty_rx_reqs array.

rx_refill_buffer is introduced to temporary storage
bulk of mbufs taken from pool.

In case of error unused mbufs are put back to pool.

15febafdd4 drivers/net: set close behaviour flag at probing
The ethdev flag RTE_ETH_DEV_CLOSE_REMOVE is set for drivers
having migrated to the new behaviour of rte_eth_dev_close().

As any other flag, it can be useful to know about its value
as soon as the port is probed.
Unfortunately, it was set inside the close operation,
just before being erased by memset() in rte_eth_dev_release_port().
The flag assignment is moved to the probing stage, so it can
be checked by the application in order to anticipate the behaviour.

4d7877fde2 net/ena: remove resources when port is being closed
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().

df238f84c0 net/ena: recreate HW IO rings on start and stop
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.
