9970a9ad07 ethdev: make stats and xstats reset callbacks return int
Change return value of the callbacks from void to int. Make
implementations across all drivers return negative errno
values in case of error conditions.

Both callbacks are updated together because a large number of
drivers assign the same function to both callbacks.

6bee9d5f45 drivers/net: use ack in interrupt handlers
Replace rte_intr_enable() with rte_intr_ack() API
for acking an interrupt in interrupt handlers and
rx_queue_intr_enable() callbacks of PMD's.

This is inline with original intent of this change in PMDs
to ack interrupts after handling is completed if
device is backed by UIO, IGB_UIO or VFIO(with INTx).

b76fafb174 eal: fix IOVA mode selection as VA for PCI drivers
The incriminated commit broke the use of RTE_PCI_DRV_IOVA_AS_VA which
was intended to mean "driver only supports VA" but had been understood
as "driver supports both PA and VA" by most net drivers and used to let
dpdk processes to run as non root (which do not have access to physical
addresses on recent kernels).

The check on physical addresses actually closed the gap for those
drivers. We don't need to mark them with RTE_PCI_DRV_IOVA_AS_VA and this
flag can retain its intended meaning.
Document explicitly its meaning.

We can check that a driver requirement wrt to IOVA mode is fulfilled
before trying to probe a device.

Finally, document the heuristic used to select the IOVA mode and hope
that we won't break it again.

Fixes: 703458e19c ("bus/pci: consider only usable devices for IOVA mode")

29a62d1476 net/nfp: add CPP bridge as service
The Netronome's Network Flow Processor chip is highly programmable
with the goal of processing packets at high speed. Processing units
and other chip components are available from the host through the
PCIe CPP(Command Push Pull bus) interface. The NFP PF PMD configures
a CPP handler for setting up and working with vNICs, perform actions
like link up or down, or accessing extended stats from the MAC component.

There exist NFP host tools which access the NFP components for
programming and debugging but they require the CPP interface. When the
PMD is bound to the PF, the DPDK app owns the CPP interface, so these
host tools can not access the NFP through other means like NFP kernel
drivers.

This patch adds a CPP bridge using the rte_service API which can be
enabled by a DPDK app. Interestingly, DPDK clients like OVS will not
enable specific service cores, but this can be performed with a
secondary process specifically enabling this CPP bridge service and
therefore giving access to the NFP to those host tools.

ab3ce1e0c1 ethdev: remove old offload API
In DPDK 17.11, the ethdev offloads API has changed:
	commit cba7f53b71 ("ethdev: introduce Tx queue offloads API")
	commit ce17eddefc ("ethdev: introduce Rx queue offloads API")
The new API is documented in the programmer's guide:
	http://doc.dpdk.org/guides/prog_guide/poll_mode_drv.html#hardware-offload

For reminder, the main concepts in the new API were:
	- All offloads are disabled by default
	- Distinction between per port and per queue offloads.

The transition bits are now removed:
	- Translation of the old API in ethdev
	- rte_eth_conf.rxmode.ignore_offload_bitfield
	- ETH_TXQ_FLAGS_IGNORE

The old API bits are now removed:
	- Rx per-port rte_eth_conf.rxmode.[bit-fields]
	- Tx per-queue rte_eth_txconf.txq_flags
	- ETH_TXQ_FLAGS_NO*

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.

342a7bdd6e net/nfp: avoid access to sysfs resource0 file
NFP CPP interface dinamically configures NFP CPP BARs for accessing
any NFP chip component from user space. This requires to map PCI BAR
regions specifically. However, this does not require to do such map
over the usual map done by VFIO or UIO drivers with the device PCI
BARs.

This patch avoids this remapping and therefore also avoids to access
the device sysfs resource0 file for doing that remapping.

4c27985f05 net/nfp: avoid sysfs resource file access
Getting the bar size is required for NFP CPP interface configuration.
However, this information can be obtained from the VFIO or UIO driver
instead of accessing the sysfs resource file.

ebf2ed7208 net/nfp: use generic PCI config access functions
This patch avoids direct access to device config sysfs file using
rte_pci_read_config instead.

Apart from replicating code, it turns out this direct access does
not always work if non-root users execute DPDK apps. In those cases
it is mandatory to go through VFIO specific function for reading pci
config space.

TX descriptor eop_offset field is not initialized and it could
contain garbage. This patch fixes the potential problem setting
EOP as the only subfield. The other subfield, data offset, is

5f6ed2f4e0 net/nfp: fix lock file usage
DPDK apps can be executed as non-root users but current NFP lock
file for avoiding concurrent accesses to CPP interface is precluding
this option or requires to modify system file permissions.

When the NFP device is bound to VFIO, this driver does not allow this
concurrent access, so the lock file is not required at all.

OVS-DPDK as executed in RedHat distributions is the main NFP user
needing this fix.
