Therefore, when two virtio devices have different flags, it may lead to

i40e: simplify SSE packet length extraction code
In Table 8-16 of the "Intel® Ethernet Controller XL710 Datasheet" it is
stated that when the whole packet is written to a single buffer, the
header length field in the descriptor will be 0. This means that when
extracting the packet/data_len field from the descriptor in the driver
we do not need to mask out the extra header-length bits.
Inside the vector driver, this reduces the need to pull all four pktlen
fields into a single register to work on. Instead of a shift and mask,
we now need to only do a shift. Therefore, we can work on each descriptor
independently, processing each using one shift intrinsic and a blend.
This change makes the code shorter and easier to read, so we can pull it
into the main descriptor processing loop instead of needing its own
function. This in turn makes the descriptor processing in the loop as a
whole slightly easier to read as it's more linear.
In terms of performance, in testing this change shows little effect, with
single-core perf tests showing a very slight improvement.

i40e: improve performance of vector PMD
An analysis of the i40e code using Intel® VTune™ Amplifier 2016 showed
that the code was unexpectedly causing stalls due to "Loads blocked by
Store Forwards". This can occur when a load from memory has to wait
due to the prior store being to the same address, but being of a smaller
size i.e. the stored value cannot be directly returned to the loader.
[See ref: https://software.intel.com/en-us/node/544454]
These stalls are due to the way in which the data_len values are handled
in the driver. The lengths are extracted using vector operations, but those
16-bit lengths are then assigned using scalar operations i.e. 16-bit
stores.
These regular 16-bit stores actually have two effects in the code:
* they cause the "Loads blocked by Store Forwards" issues reported
* they also cause the previous loads in the RX function to actually be a
load followed by a store to an address on the stack, because the 16-bit
assignment can't be done to an xmm register.
By converting the 16-bit store operations into a sequence of SSE blend
operations, we can ensure that the descriptor loads only occur once, and
avoid both the additional stores and loads from the stack, as well as the
stalls due to the blocked loads.

qede: add interrupt handling support
The physical link is handled by the management Firmware.
This patch lays the infrastructure for interrupt/attention handling in
the driver, as link change notifications arrive via async interrupts,
as well as the handling of such notifications. It adds async event
notification handler interfaces to the PMD.

qede: add core driver
The Qlogic Everest Driver for Ethernet(QEDE) Poll Mode Driver(PMD) is
the DPDK specific module for QLogic FastLinQ QL4xxxx 25G/40G CNA family
of adapters as well as their virtual functions (VF) in SR-IOV context.
This patch adds QEDE PMD, which interacts with base driver and
initialises the HW.
This patch content also includes:
- eth_dev_ops callbacks
- Rx/Tx support for the driver
- link default configuration
- change link property
- link up/down/update notifications
- vlan offload and filtering capability
- device/function/port statistics
- qede nic guide and updated overview.rst
Note that the follow on commits contain the code for the features mentioned
in documents but not implemented in this patch.

qede: add base driver
The base driver is the backend module for the QLogic FastLinQ QL4xxxx
25G/40G CNA family of adapters as well as their virtual functions (VF)
in SR-IOV context.
The purpose of the base module is to:
- provide all the common code that will be shared between the various
drivers that would be used with said line of products. Flows such as
chip initialization and de-initialization fall under this category.
- abstract the protocol-specific HW & FW components, allowing the
protocol drivers to have clean APIs, which are detached in its
slowpath configuration from the actual Hardware Software Interface(HSI).
This patch adds a base module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.

ixgbe: fix bit shift overflow in VMDQ pool setup
Fix issue reported by Coverity.
Coverity ID 13193: Bad bit shift operation (BAD_SHIFT)
large_shift: In expression 1 << pool, left shifting by more than 31 bits
has undefined behavior. The shift amount, pool, is at least 32.
This patch is a rework of register addr selection logic and mask
computation to made it more readable and avoid bit overflow when 32 bit
value is shifted over its size for pool > 31.

i40e: fix packet count stats
The statistics queried by calling rte_eth_stats_get are zero when
the API is first called on the port. The root cause is because the
offset_loaded flag is not set correctly after device start.
This patch fixes this issue by resetting statistics at initialization
time. The resetting process will set offset_loaded flag.
