54dcfdee85 drivers/raw: standardize naming
The driver names for rawdevs were both different in make and meson builds
and were non-standard in the make version in that some included "rawdev" in
the name while others didn't.

Therefore, for global consistency of naming, we can use "rte_rawdev" rather
than "rte_pmd" for the prefix for the libraries. While most other driver
categories use "rte_pmd" as a prefix, there is precedent for this in the
mempool drivers use "rte_mempool" as a prefix.

2579543f60 net/mlx5: handle LRO packets in regular Rx queue
When LRO offload is configured in Rx queue, the HW may coalesce TCP
packets from same TCP connection into single packet.

In this case the SW should fix the relevant packet headers because
the HW doesn't update them according to the new created packet
characteristics but provides the update values in the CQE.

Add update header code to the regular Rx burst function to support LRO
feature.

Make sure the first mbuf has enough space to include each TCP header,
otherwise the header update may cross mbufs what complicates the
operation too match.

This patch introduces new mlx5 PMD devarg options:

- txq_inline_min - specifies minimal amount of data to be inlined into
  WQE during Tx operations. NICs may require this minimal data amount
  to operate correctly. The exact value may depend on NIC operation
  mode, requested offloads, etc.

- txq_inline_max - specifies the maximal packet length to be completely
  inlined into WQE Ethernet Segment for ordinary SEND method. If packet
  is larger the specified value, the packet data won't be copied by the
  driver at all, data buffer is addressed with a pointer. If packet
  length is less or equal all packet data will be copied into WQE.

- txq_inline_mpw - specifies the maximal packet length to be completely
  inlined into WQE for Enhanced MPW method.

Driver documentation is also updated.

This patch removes the existing Tx datapath code

- incompatible Tx completion code

The following devargs are deprecated and ignored:
- "txq_inline" is going to be converted to "txq_inline_max"
  for compatibility issue
- "tx_vec_en"
- "txqs_max_vec"
- "txq_mpw_hdr_dseg_en"
- "txq_max_inline_len" is going to be converted
  to "txq_inline_mpw" for compatibility issue

The deprecated devarg keys are recognized by PMD
and ignored/converted to the new ones in order not
to block device probing.

6937d2103e app/testpmd: add option to not start device
Some configuration options can not be tested properly with testpmd
because it automatically starts all ports. This makes it harder
to test driver handling of configuration options:
(for example rx_deferred_start).

Add new command line flag --disable-device-start which skips
the device start. The port can then be started manually later.

55e51c9624 app/testpmd: add device related commands
With the latest published interface of
rte_eal_hotplug_[add,remove](), and rte_eth_dev_close(),
rte_eth_dev_close() would cleanup all the data structures of
port's eth dev leaving the device common resource intact
if RTE_ETH_DEV_CLOSE_REMOVE is set in dev flags.

So a new command "detach device" (~hotplug remove) to work,
with device identifier like "port attach" is added
to be able to detach closed devices.

Also to display currently probed devices, another command
"show device info <identifier>|all" is also added as a
part of this change.

30626def03 app/testpmd: support raw encap/decap actions
This patch intend to support
action_raw_encap/decap [1] in a generic and convenient way.

Two new commands - set raw_encap, set raw_decap are introduced just
like the other commands for encap/decap, i.e. set vxlan.

These two commands have corresponding global buffers
which can be used by PMD as the input buffer for raw encap/decap.

The commands use the rte_flow pattern syntax to help user build the
raw buffer in a convenient way.

A common way to use it:

- encap matched egress packet with VxLAN tunnel:
testpmd> set raw_encap eth src is 10:11:22:33:44:55 / vlan tci is 1
	 inner_type is 0x0800 / ipv4 / udp dst is 4789 / vxlan vni
	 is 2 / end_set
testpmd> flow create 0 egress pattern eth / ipv4 / end actions
	 raw_encap / end

- decap l2 header and encap GRE tunnel on matched egress packet:
testpmd> set raw_decap eth / end_set
testpmd> set raw_encap eth dst is 10:22:33:44:55:66 / ipv4 / gre
	 protocol is 0x0800 / end_set
testpmd> flow create 0 egress pattern eth / ipv4 / end actions
	 raw_decap / raw_encap / end

- decap VxLAN tunnel and encap l2 header on matched ingress packet:
testpmd> set raw_encap eth src is 10:11:22:33:44:55 type is 0x0800 /
	 end_set
testpmd> set raw_decap eth / ipv4 / udp / vxlan / end_set
testpmd> flow create 0 ingress pattern eth / ipv4 / udp dst is 250 /
         vxlan vni is 0x1234 / ipv4 / end actions raw_decap /
         raw_encap / queue index 1 / mark id 0x1234 / end

f14a945915 net/pcap: remove Rx queue argument necessity
Previously in the PCAP PMD queues has to be defined as RxQ and TxQ
pairs, even if the need is only Rx or only Tx:
 "--vdev net_pcap0,tx_pcap=tx.pcap,rx_pcap=rx.pcap"

Following commit enabled only providing Rx queue, and if Tx queue is
not provided PMD drops the Tx packets automatically:
Commit a3f5252e5c ("net/pcap: enable infinitely Rx a pcap file")
 "--vdev net_pcap0,rx_pcap=rx.pcap"

This commit enables same thing for Rx queue, user no more have to
provide a Rx queue (rx_iface or rx_pcap), for this case a dummy Rx
burst function is used which doesn't return any packet at all:
 "--vdev net_pcap0,tx_pcap=tx.pcap"

This makes only saving packets to a pcap file use case easy.

When both Rx and Tx queues are missing PMD will return an error.
(Single interface is still supported: "--vdev net_pcap0,iface=eth0")

f15db67df0 net/mlx5: accelerate DV flow counter query
All the DV counters are cashed in the PMD memory and are contained in
pools which are contained in containers according to the counters
allocation type - batch or single.

Currently, the flow counter query is done synchronously in pool
resolution means that on the user request a FW command is triggered to
read all the counters in the pool.

A new feature of devX to asynchronously read batch of flow counters
allows to accelerate the user query operation.

Using the DPDK host thread, the PMD periodically triggers asynchronous
query in pool resolution for all the counter pools and an interrupt is
triggered by the FW when the values are updated.
In the interrupt handler the pool counter values raw data is replaced
using a double buffer algorithm (very fast).
In the user query, the PMD just returns the last query values from the
PMD cache - no system-calls and FW commands are triggered from the user
control thread on query operation!

More synchronization is added with the host thread:
        Container resize uses double buffer algorithm.
        Pools growing in container uses atomic operation.
        Pool query buffer replace uses a spinlock.
        Pool minimum devX counter ID uses atomic operation.

bbe29a9bd7 eal/linux: select IOVA as VA mode for default case
When bus layer reports the preferred mode as RTE_IOVA_DC then
select the RTE_IOVA_VA mode:

- All drivers work in RTE_IOVA_VA mode, irrespective of physical
address availability.

- By default, a mempool asks for IOVA-contiguous memory using
RTE_MEMZONE_IOVA_CONTIG. This is slow in RTE_IOVA_PA mode and it
may affect the application boot time.

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")
