null checks to before the offending use of the pointer.

07491889d1 net/i40e: fix offload flags for vector Rx
The flags for RSS and flow director are not set correctly in the vector
Rx function, so applications which use these flags will not work
correctly.

The problem is caused by incorrect constants for masking,
shuffling and shifting the descriptor bytes, to create the resultant
flags in the mbuf. Correcting the constants fixes the problem

6046898f50 net/mbuf: remove unused Rx error flags
Following the discussions from:
http://dpdk.org/ml/archives/dev/2015-July/021721.html
http://dpdk.org/ml/archives/dev/2016-April/038143.html

The value of these flags is 0, making them useless. Today, no example
application checks them on Rx, and only few drivers sets them and
silently give wrong packets to the application, which should not happen.

This patch removes the unused flags from rte_mbuf and their use in the
drivers. The i40e and fm10k are kept as they are today and should be
fixed to drop bad packets. The enic driver is managed by its maintainer
in another patch.

ca7e599d45 net/i40e: fix link management
Previously, there was a known issue "On Intel® 40G Ethernet
Controller stopping the port does not really down the port link."

There were two reasons why the port was always kept up.
1. Old firmware versions had issues when "Set PHY config command"
   was used on 40G NICs.
2. The kernel i40e driver didn't call "Set PHY config command" when
   ifconfig up/down was used, it assumes the link is always up. But
   in DPDK, ports are forced down when an applications quits. So if
   the port is then switched to being controlled by kernel the driver,
   the port can not be brought up through "ifconfig <ethx> up".

This patch fixes this issue by adding in "Set PHY config command"
into our driver. This is now possible because with newer firmware
there is no longer a problem using this command.

With this fix, after DPDK quit, if the port is switched to being used
by the kernel driver, "ethtool -s <ethx> autoneg on" can be used to
turn on the auto negotiation, and then port can be brought up through
"ifconfig <ethx> up".
NOTE: requires kernel i40e driver version >= 1.4.X

b37b528d95 mbuf: add new Rx flags for stripped VLAN
The behavior of PKT_RX_VLAN_PKT was not very well defined, resulting in
PMDs not advertising the same flags in similar conditions.

Following discussion in [1], introduce 2 new flags PKT_RX_VLAN_STRIPPED
and PKT_RX_QINQ_STRIPPED that are better defined:

  PKT_RX_VLAN_STRIPPED: a vlan has been stripped by the hardware and its
  tci is saved in mbuf->vlan_tci. This can only happen if vlan stripping
  is enabled in the RX configuration of the PMD.

For now, the old flag PKT_RX_VLAN_PKT is kept but marked as deprecated.
It should be removed from applications and PMDs in a future revision.

This patch also updates the drivers. For PKT_RX_VLAN_PKT:

- e1000, enic, i40e, mlx5, nfp, vmxnet3: done, PKT_RX_VLAN_PKT already
  had the same meaning than PKT_RX_VLAN_STRIPPED, minor update is
  required.
- fm10k: done, PKT_RX_VLAN_PKT already had the same meaning than
  PKT_RX_VLAN_STRIPPED, and vlan stripping is always enabled on fm10k.
- ixgbe: modification done (vector and normal), the old flag was set
  when a vlan was recognized, even if vlan stripping was disabled.
- the other drivers do not support vlan stripping.

For PKT_RX_QINQ_PKT, it was only supported on i40e, and the behavior was
already correct, so we can reuse the same bit value for
PKT_RX_QINQ_STRIPPED.

35245e4438 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.

0b6493fbb0 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.

a61dc000d5 ethdev: remove deprecated statistics
Some statistics were deprecated since release 2.1 (49f386542a).
The last deprecated counter to be used was imcasts.

The VF loopback statistics are also removed as they are used only
in igb and duplicated in extended statistics.

The new counters should be added to extended statistics.

c28aad21a9 i40e: fix TSO
Issue:

when using the following CLI in testpmd to enable ipv6 TSO feature
(set --txqflags=0 in the testpmd command)
	set verbose 1
	csum set ip hw 0
	csum set udp hw 0
	csum set tcp hw 0
	csum set sctp hw 0
	csum set outer-ip hw 0
	csum parse_tunnel on 0
	tso set 800 0
	set fwd csum
	start

We will not get what we want, the ipv6 packets sent out from IXIA can be
received by i40e, but cannot forward to another port.
The root cause is when HW doing the TSO offload for packets, it does not only
depends on the context descriptor to define the MSS and TSO payload size, it
also need to know whether this packets is ipv4 or ipv6, we use
i40e_txd_enable_checksum to generate the related fields for data descriptor.
But PMD will not call i40e_txd_enable_checksum if only the TSO offload flag is
set. The reason why ipv4 works fine for TSO in testpmd csum mode is csum engine
will set the ip csum flag when the packet is ipv4 and TSO is enabled but
will not set the flag for ipv6 and this flag will cause the
i40e_txd_enable_checksum to be invoked. For both the cases the TSO flag will be
set, so we need to use TSO flag to trigger the i40e_txd_enable_checksum.
The right logic here is we enable csum offload for both ipv4 and ipv6 when TSO
flag is set.

2a73125b70 i40evf: fix link info update
The issue is the VF's link speed kept as 10G and status always was up.
It did not change even the physical link's status changed.
This patch fixes this issue to make VF's link info consistent with
physical link.

82113036e4 ethdev: redesign link speed config
This patch redesigns the API to set the link speed/s configuration
of an ethernet port. Specifically:

- it allows to define a set of advertised speeds for
  auto-negociation.
- it allows to disable link auto-negociation (single fixed speed).
- default: auto-negociate all supported speeds.

A flag autoneg in struct rte_eth_link indicates if link speed was a
result of auto-negociation or was fixed by configuration.

e274f57322 ethdev: add speed capabilities
The speed capabilities of a device can be retrieved with
rte_eth_dev_info_get().

The new field speed_capa is initialized in the drivers without
taking care of device characteristics in this patch.
When the capabilities of a driver are accurate, the table in
overview.rst must be filled.

34fcd34982 i40e: fix crash on DCB query
Calling rte_eth_dev_get_dcb_info to get dcb info from i40e
driver if VMDQ is disabled, results in a segmentation fault.
This patch fixes it by treating VMDQ and No-VMDQ respectively
when querying dcb information.
