cbb66daa3c net/mlx5: prepare Direct Verbs for Direct Rule
This is the first patch of a series that is designed to enable the
Direct Rules API.

The main difference between Direct Verbs and Direct Rules from API
perspective is that in Direct Rules each action has it's own create
function and the object itself is of type void.

In this patch I'm adding functions to generate actions that currently
are done without create action, and I'm changing the action type to be
void *, so in next patches only the glue functions will need to change.

9a8ab29b84 net/mlx5: replace IPC socket with EAL API
Socket API is used for IPC in order for secondary process to acquire
Verb command file descriptor. The FD is used to remap UAR address.
The multi-process APIs (rte_mp) in EAL are newly introduced.
mlx5_socket.c is replaced with mlx5_mp.c, which uses the new APIs.

As it is PMD global infrastructure, only one IPC channel is established.
All the IPC message types may have port_id in the message if there is
need to reference a specific device.

299d7dc28c net/mlx5: add representor recognition on Linux 5.x
The master device and VF representors were distinguished by
presence of port name, master device did not have one. The new Linux
kernels starting from 5.0 provide the port name for master device
and the implemented representor recognizing method does not work.
The new recognizing method is based on querying the VF number,
has been created on the base of the device.

The IFLA_NUM_VF attribute is returned by kernel if IFLA_EXT_MASK
attribute is specified in the Netlink request message.

Also the presence check of device symlink in device sysfs folder
is added to distinguish representors with sysfs based method.

bc91e8db12 net/mlx5: add 128B padding of Rx completion entry
A PMD parameter (rxq_cqe_pad_en) is added to enable 128B padding of CQE on
RX side. The size of CQE is aligned with the size of a cacheline of the
core. If cacheline size is 128B, the CQE size is configured to be 128B even
though the device writes only 64B data on the cacheline. This is to avoid
unnecessary cache invalidation by device's two consecutive writes on to one
cacheline. However in some architecture, it is more beneficial to update
entire cacheline with padding the rest 64B rather than striding because
read-modify-write could drop performance a lot. On the other hand, writing
extra data will consume more PCIe bandwidth and could also drop the maximum
throughput. It is recommended to empirically set this parameter. Disabled
by default.

macros:

- HAVE_IBV_DEVICE_COUNTERS_SET_V42 - is defined if system supports
  the "old" flow counters functionality, MLNX_OFED version from
  4.2 to 4.4 is required.

- HAVE_IBV_DEVICE_COUNTERS_SET_V45 - is defined if system supports
  the "new" flow counters functionality, MLNX_OVED 4.5 (or higher)
  or Linux rdma-core v19 (or higher) is required.

Neither HAVE_IBV_DEVICE_COUNTERS_SET_V42 nor
HAVE_IBV_DEVICE_COUNTERS_SET_V45 is defined if there is no
counters support.

31fda51877 net/mlx5: support multiple groups and jump action
rte_flow has 'group' attribute and 'jump' action in order to support
multiple groups. This feature is known as multi-table support ('chain' in
linux TC flower) in general because a group means a table of flows. Example
commands are:

	flow create 0 transfer priority 1 ingress
	     pattern eth / vlan vid is 100 / end
	     actions jump group 1 / end

	flow create 0 transfer priority 1 ingress
	     pattern eth / vlan vid is 200 / end
	     actions jump group 2 / end

	flow create 0 transfer group 1 priority 2 ingress
	     pattern eth / vlan vid is 100 /
	     	     ipv4 dst spec 192.168.40.0 dst prefix 24 / end
	     actions drop / end

	flow create 0 transfer group 1 priority 2 ingress
	     pattern end
	     actions of_pop_vlan / port_id id 1 / end

	flow create 0 transfer group 2 priority 2 ingress
	     pattern eth / vlan vid is 200 /
	     	     ipv4 dst spec 192.168.40.0 dst prefix 24 / end
	     actions of_pop_vlan / port_id id 2 / end

	flow create 0 transfer group 2 priority 2 ingress
	     pattern end
	     actions port_id id 2 / end

With theses flows, if a packet having vlan 200 and src_ip as 192.168.40.1,
this packet will firstly hit the 1st flow. Then it will hit the 5th flow
because of the 'jump' action. As a result, the packet will be forwarded to
port 2 (VF representor) with vlan tag being stripped off. If the packet had
vlan 100 instead, it would be dropped by the 3rd flow.

8f9059ccee net/mlx5: add framework for switch flow rules
Because mlx5 switch flow rules are configured through Netlink (TC
interface) and have little in common with Verbs, this patch adds a separate
parser function to handle them.

- mlx5_nl_flow_transpose() converts a rte_flow rule to its TC equivalent
  and stores the result in a buffer.

- mlx5_nl_flow_brand() gives a unique handle to a flow rule buffer.

- mlx5_nl_flow_create() instantiates a flow rule on the device based on
  such a buffer.

- mlx5_nl_flow_destroy() performs the reverse operation.

These functions are called by the existing implementation when encountering
flow rules which must be offloaded to the switch (currently relying on the
transfer attribute).

20b71e92ef net/mlx5: lay groundwork for switch offloads
With mlx5, unlike normal flow rules implemented through Verbs for traffic
emitted and received by the application, those targeting different logical
ports of the device (VF representors for instance) are offloaded at the
switch level and must be configured through Netlink (TC interface).

This patch adds preliminary support to manage such flow rules through the
flow API (rte_flow).

Instead of rewriting tons of Netlink helpers and as previously suggested by
Stephen [1], this patch introduces a new dependency to libmnl [2]
(LGPL-2.1) when compiling mlx5.

The flow counter support introduced by

work only with MLNX_OFED_4.3 as the upstream rdma-core
libraries were lack such support.

On rdma-core v19 the support for the flow counters was added but with
different user APIs, hence causing compilation issues on the PMD.

This patch fix the compilation errors by forcing the flow counters
to be enabled only with MLNX_OFED APIs.
Once MLNX_OFED and rdma-core APIs will be aligned, a proper patch to
support the new API will be submitted.

Problem is that more often than not, the wrong Verbs device is used,
resulting in unexpected traffic.

This patch makes the driver discard representors to only use the master
device. If unable to identify it (e.g. kernel drivers not recent enough),
either:

- There is only one matching device which isn't identified as a
  representor, in that case use it.
- Otherwise log an error and do not probe the device.

(Patch based on prior work from Yuanhan Liu)

1787eb7b4d net/mlx5: use stride index in Rx completion entry
Multi-Packet Receive Queue is to receive multiple packets on a single large
buffer. The number of consumed strides in CQE is accumulated to keep track
of the current stride index. However, it is safer to directly use stride
index in CQE to avoid out-of-order situation which can possibly be caused
by introducing LRO in the future.

If Rx CQE compression is enabled, HW can be configured to store the stride
index in a mini-CQE but this will need newer version of library/driver.
Therefore, since this change, MPRQ is only supported with the newer
library/driver and Rx hash result is not supported if MPRQ is enabled along
with Rx CQE compression.

a11dfe9b65 net/mlx: fix warnings for unused compiler arguments
When linking the mlx glue code libraries using CC, the linker arguments in
LDFLAGS are not prefixed with -Wl. [The EXTRA_LDFLAGS are though.] This
leads to warning messages on build:

clang-5.0: warning: argument unused during compilation: '-e xport-dynamic'

Fix this by checking for $LINK_USING_CC in the Makefiles and prefixing the
LDFLAGS appropriately if set.

038e72511f net/mlx5: fix tunnel offloads cap query
The query for the tunnel stateless offloads is wrongly implemented
because of:

1. It was using the device id to query for the offloads.
2. It was using a compilation flag for Verbs which no longer exits.

The main reason was lack of proper API from Verbs.

Fixing the query to use rdma-core API. The capability returned from
rdma-core refer to both Tx and Rx sides.
Eventhough there is a separate cap for GRE and VXLAN, implementation merge
them into a single flag in order to simplify the checks on the data
path.

6d5df2eaf6 net/mlx: version rdma-core glue libraries
When built as separate objects, these libraries do not have unique names.
Since they do not maintain a stable ABI, loading an incompatible library
may result in a crash (e.g. in case multiple versions are installed).

This patch addresses the above by versioning glue libraries, both on the
file system (version suffix) and by comparing a dedicated version field
member in glue structures.
