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.

i40e: require SSE4.1 support for vector driver
Later commits to improve the driver will make use of the SSE4.1
_mm_blend_epi16 intrinsic, so:
* set the compilation level to always have SSE4.1 support,
* and add in a runtime check for SSE4.1 as part of the condition checks
for vector driver selection.

lpm: fix freeing in compatibility mode
Back then when we fixed the missing free lpm I was to quickly to say yes
if it applies not only to the lpm6 but also to all of the lpm code.
It turned out to not apply to all of them. In rte_lpm_create_v20 there
is an unexpected fused allocation:
mem_size = sizeof(*lpm) + (sizeof(lpm->rules_tbl[0]) * max_rules);
[...]
lpm = (struct rte_lpm_v20 *)rte_zmalloc_socket(mem_name,mem_size,
RTE_CACHE_LINE_SIZE, socket_id);
That causes lpm->rules_tbl not to have an own struct malloc_elem that
can be derived via RTE_PTR_SUB(data, MALLOC_ELEM_HEADER_LEN) in
malloc_elem_from_data.
Due to that the rte_lpm_free_v20 accidentially misderives the elem and
assumes it is ELEM_FREE triggering in malloc_elem_free
if (!malloc_elem_cookies_ok(elem) || elem->state !=
return -1;
While it seems counter-intuitive the way to properly remove rules_tbl in
the old fused allocation style of rte_lpm_free_v20 is to not remove it.
The newer rte_lpm_free_v1604 is safe because in rte_lpm_create_v1604
rules_tbl is a separate allocation.

scripts: check commit formatting
The git messages have three parts:
1/ the headline
2/ the explanations
3/ the footer tags
The headline helps to quickly browse an history or catch instantly the
purpose of a commit. Making it short with some consistent wording
allows to easily parse it or match some patterns.
The explanations must give some keys like the reason of the change.
Nothing can be automatically checked for this part, except line length.
The footer contains some tags to find the origin of a bug or who
was working on it.
This script is doing some basic checks mostly on parts 1 and 3.

port: fix ring writer buffer overflow
Fixes the buffer overflow that occurs due to following;
1. When the input packet burst does not meet the conditions: (a) being
contiguous (first n bits set in pkts_mask, all the other bits cleared)
and (b) containing a full burst, i.e. at least tx_burst_sz packets
(n >= tx_burst_size). This is the slow(er) code path taken when local
variable expr != 0.
2. There are some packets already in the buffer.
3. The number of packets in the incoming burst (i.e. popcount(pkts_mask))
plus the number of packets already in the buffer exceeds the buffer size
(RTE_PORT_IN_BURST_SIZE_MAX, i.e. 64).

app/testpmd: fix running without Xen whereas enabled
With LIBRTE_PMD_XENVIRT enabled testpmd is built in a way to ONLY work
in XEN environments.
It will surface as:
PMD: gntalloc: ioctl error
EAL: Error - exiting with code: 1
Cause: Creation of mbuf pool for socket 0 failed
With LIBRTE_PMD_XENVIRT enabled this now tries the xen style grant
table allocation, but falls back gracefully for the normal allocation.
