b2fd027389 mbuf: clarify QinQ flag usage
Update implementation that when PKT_RX_QINQ_STRIPPED mbuf ol_flags
set by PMD, PKT_RX_QINQ, PKT_RX_VLAN_STRIPPED & PKT_RX_VLAN
should be also set.

Clarify mbuf documentations that when PKT_RX_QINQ set PKT_RX_VLAN also
should be set.

So that appllication can rely on PKT_RX_QINQ flag to access both
mbuf.vlan_tci & mbuf.vlan_tci_outer

c11f654042 net/i40e: add option to use latest vector path
For IA, the AVX2 vector path is only recommended to be used on later
platforms (identified by AVX512 support, like SKL etc.) This is because
performance benchmark shows downgrade when running AVX2 vector path on
early platform (BDW/HSW) in some cases. But we still observe perf gain
with some real work loading.

So this patch introduced the new devarg use-latest-supported-vec to
force the driver always selecting the latest supported vec path. Then
apps are able to take AVX2 path on early platforms. And this logic can
be re-used if we will have AVX512 vec path in future.

This patch only affects IA platforms. The selected vec path would be
like the following:
  Without devarg/devarg = 0:
  Machine	vPMD
  AVX512F	AVX2
  AVX2	SSE4.2
  SSE4.2	SSE4.2
  <SSE4.2	Not Supported

  With devarg = 1
  Machine	vPMD
  AVX512F	AVX2
  AVX2	AVX2
  SSE4.2	SSE4.2
  <SSE4.2	Not Supported

Other platforms can also apply the same logic if necessary in future.

323e7b667f ethdev: make default behavior CRC strip on Rx
Removed DEV_RX_OFFLOAD_CRC_STRIP offload flag.
Without any specific Rx offload flag, default behavior by PMDs is to
strip CRC.

PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC
Rx offload capability.

Applications that require keeping CRC should check PMD capability first
and if it is supported can enable this feature by setting
DEV_RX_OFFLOAD_KEEP_CRC in Rx offload flag in rte_eth_dev_configure()

70815c9eca ethdev: add new offload flag to keep CRC
DEV_RX_OFFLOAD_KEEP_CRC offload flag is added. PMDs that support
keeping CRC should advertise this offload capability.

DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release
default behavior in PMDs are to keep the CRC until this flag removed

Until DEV_RX_OFFLOAD_CRC_STRIP flag is removed:
- Setting both KEEP_CRC & CRC_STRIP is INVALID
- Setting only CRC_STRIP PMD should strip the CRC
- Setting only KEEP_CRC PMD should keep the CRC
- Not setting both PMD should keep the CRC

A helper function rte_eth_dev_is_keep_crc() has been added to be able to
change the no flag behavior with minimal changes in PMDs.

The PMDs that doesn't report the DEV_RX_OFFLOAD_KEEP_CRC offload can
remove rte_eth_dev_is_keep_crc() checks next release, related code
commented to help the maintenance task.

And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since
they don't use CRC at all, when an application requires this offload
virtual PMDs should not return error.

a4996bd89c ethdev: new Rx/Tx offloads API
This patch check if a input requested offloading is valid or not.
Any reuqested offloading must be supported in the device capabilities.
Any offloading is disabled by default if it is not set in the parameter
dev_conf->[rt]xmode.offloads to rte_eth_dev_configure() and
[rt]x_conf->offloads to rte_eth_[rt]x_queue_setup().
If any offloading is enabled in rte_eth_dev_configure() by application,
it is enabled on all queues no matter whether it is per-queue or
per-port type and no matter whether it is set or cleared in
[rt]x_conf->offloads to rte_eth_[rt]x_queue_setup().
If a per-queue offloading hasn't be enabled in rte_eth_dev_configure(),
it can be enabled or disabled for individual queue in
ret_eth_[rt]x_queue_setup().
A new added offloading is the one which hasn't been enabled in
rte_eth_dev_configure() and is reuqested to be enabled in
rte_eth_[rt]x_queue_setup(), it must be per-queue type,
otherwise trigger an error log.
The underlying PMD must be aware that the requested offloadings
to PMD specific queue_setup() function only carries those
new added offloadings of per-queue type.

This patch can make above such checking in a common way in rte_ethdev
layer to avoid same checking in underlying PMD.

This patch assumes that all PMDs in 18.05-rc2 have already
converted to offload API defined in 17.11 . It also assumes
that all PMDs can return correct offloading capabilities
in rte_eth_dev_infos_get().

In the beginning of [rt]x_queue_setup() of underlying PMD,
add offloads = [rt]xconf->offloads |
dev->data->dev_conf.[rt]xmode.offloads; to keep same as offload API
defined in 17.11 to avoid upper application broken due to offload
API change.
PMD can use the info that input [rt]xconf->offloads only carry
the new added per-queue offloads to do some optimization or some
code change on base of this patch.

logically grouping of APIs. From applications point of view they can't

380a7aab1a mbuf: rename deprecated VLAN flags
PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated for a while.
As explained in [1], these flags were kept to let the applications and
PMDs move to the new flag. There is also a need to support Rx vlan
offload without vlan strip (at least for the ixgbe driver).

This patch renames the old flags for this feature, knowing that some
PMDs were using PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT to indicate that
the vlan tci has been saved in the mbuf structure.

It is likely that some PMDs do not set the proper flags when doing vlan
offload, and it would be worth making a pass on all of them.

67f0380766 net/i40e: enable per-device packet type mapping
The mapping from hardware defined packet type to software defined
packet type is static for i40e device, the patch let each ethdev to
to have their own copy of mapping table, this give the possibility
that different ethdev can be set different PTYPE mapping rule which
is the requirement to support following hardware's dynamic PTYPE
feature.

5fc4acc31d net/i40e: remove limit of Tx burst size
To add a wrapper function to remove the limit of tx burst size. The patch
makes i40e vec function an best effort to transmit the pkts in the
consistent behavior like i40e_xmit_pkts_simple and i40e_xmit_pkts do that.

0be2953129 net/i40e: fix compile error
Fix the compile error when RTE_LIBRTE_I40E_RX_ALLOW_BULK_ALLOC
is disabled.

Also fake_mbuf is required to be initialized and assigned to
additional sw_ring entries for vector PMD independent from
RTE_LIBRTE_I40E_RX_ALLOW_BULK_ALLOC config option.

0ef850c4f6 ethdev: move a queue id check to generic layer
The check of queue_id is done in all drivers implementing
rte_eth_rx_queue_count(). Factorize this check in the generic function.

Note that the nfp driver was doing the check differently, which could
induce crashes if the queue index was too big.

PKT_TX_TUNNEL_MASK and PKT_TX_IEEE1588_TMST are missed in bitmask
of all supported packet Tx flags by i40e. It will cause packet preparing
fail when sending tunnel packets with Tx offload.
This patch fixes it.
