b0a688a542 rdma: Rewrite custom JSON and prints logic to use common API
Instead of doing open-coded solution to generate JSON and prints, let's
reuse existing infrastructure and APIs to do the same as ip/*.

Before this change:
 if (rd->json_output)
     jsonw_uint_field(rd->jw, "sm_lid", sm_lid);
 else
     pr_out("sm_lid %u ", sm_lid);

After this change:
 print_uint(PRINT_ANY, "sm_lid", "sm_lid %u ", sm_lid);

All the print functions are converted to support color but for now the
type of color is COLOR_NONE. This is done as a preparation to addition
of color enable option. Such change will require rewrite of command line
arguments parser which is out-of-scope for this patch.

887fc739eb rdma: Add rdma statistic counter per-port auto mode support
With per-QP statistic counter support, a user is allowed to monitor
specific QPs categories, which are bound to/unbound from counters
dynamically allocated/deallocated.

In per-port "auto" mode, QPs are bound to counters automatically
according to common criteria. For example a per "type"(qp type)
scheme, where in each process all QPs have same qp type are bind
automatically to a single counter.
Currently only "type" (qp type) is supported. Examples:

$ rdma statistic qp set link mlx5_2/1 auto type on
$ rdma statistic qp set link mlx5_2/1 auto off

1b2ca7ada7 rdma: Add get per-port counter mode support
Add an interface to show which mode is active. Two modes are supported:
- "auto": In this mode all QPs belong to one category are bind automatically
  to a single counter set. Currently only "qp type" is supported;
- "manual": In this mode QPs are bound to a counter manually.

Examples:

1/1: mlx5_1/1: qp auto off
2/1: mlx5_2/1: qp auto type on

This patch presents link, id, task name, lqpn, as well as all sub

bound with one or more QPs. It has several sub-counters, each is
used for a different purpose.

331152752a rdma: print driver resource attributes
This enhancement allows printing rdma device-specific state, if provided
by the kernel. This is done in a generic manner, so rdma tool doesn't
need to know about the details of every type of rdma device.

Driver attributes for a rdma resource are in the form of <key,
[print_type], value> tuples, where the key is a string and the value can
be any supported driver attribute. The print_type attribute, if present,
provides a print format to use vs the standard print format for the type.
For example, the default print type for a PROVIDER_S32 value is "%d ",
but "0x%x " if the print_type of PRINT_TYPE_HEX is included inthe tuple.

Driver resources are only printed when the -dd flag is present.
If -p is present, then the output is formatted to not exceed 80 columns,
otherwise it is printed as a single row to be grep/awk friendly.

Example output:

# rdma resource show qp lqpn 1028 -dd -p
link cxgb4_0/- lqpn 1028 rqpn 0 type RC state RTS rq-psn 0 sq-psn 0 path-mig-state MIGRATED pid 0 comm [nvme_rdma]

2. Provide illegal port number (0 is illegal):
$ rdma res show qp link mlx5_4/0
Wrong device name

3. Get QPs of specific port:
$ rdma res show qp link mlx5_4/1
link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core]
link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core]
link mlx5_4/1 lqpn 0 type SMI state RTS sq-psn 0 pid 0 comm [ib_core]

4. Get QPs which have not assigned port yet:
link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib]

5. Limit to specific Local QPNs:
$ rdma res show qp link mlx5_4/1 lqpn 1-3,7
link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core]
link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core]
link mlx5_4/1 lqpn 0 type SMI state RTS sq-psn 0 pid 0 comm [ib_core]

. Filter types (strings):
$ rdma res show qp link mlx5_4/1 type UD,gSi
link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core]
link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core]

1174be72d1 rdma: Add filtering infrastructure
This patch adds general infrastructure to RDMAtool to handle various
filtering options needed for the downstream resource tracking patches.

The infrastructure is generic and stores filters in list of key<->value
entries. There are three types of filters:

1. Numeric - the values are intended to be digits combined with '-' to
mark range and ',' to mark multiple entries, e.g. pid 1-100,234,400-401
is perfectly legit filter to limit process ids.

2. String - the values are consist from strings and "," as a denominator.

3. Link - special case to allow '/' in string to provide link name, e.g.
link mlx4_1/2.

6416d1a01f rdma: Add option to provide "-" sign for the port number
According to the IBTA spec [1], the physical connected port is provided
for the QP in RTR-to-INIT stage performed by modify_qp(). It causes
to do not have port number for newly created QPs.

The following patch adds "-" sign to present absence of port, because
QPs are going to be associated with rdmatool link object, which needs
port number as an index.

b1e6bc437f rdma: Get rid of dev_map_free call
The dev_map_free() is called once only and it is short,
so it is better to integrate it into the caller's site.

8b92a2c930 rdma: Move per-device handler function to generic code

and will implement the same logic. Move the code to utils.c,
so other objects will be able to reuse the code.

99da90326e rdma: Protect dev_map_lookup from wrong input
Despite the fact that all callers to dev_map_lookup are ensuring that
there is always device name prior to call to that function, it is better
and safer to check that in the dev_map_lookup itself.

74bd75c2b6 rdma: Add basic infrastructure for RDMA tool
RDMA devices are cross-functional devices from one side,
but very tailored for the specific markets from another.

Such diversity caused to spread of RDMA related configuration
across various tools, e.g. devlink, ip, ethtool, ib specific and
vendor specific solutions.

This patch adds ability to fill device and port information
by reading RDMA netlink.
