In iproute2 package, the updates of UAPIs files are performed
after the needed feature lands in kernel's net-next tree.
Such development flow created delays to the rdma tool developers,
who uses rdma-next tree as a basis for their work.
Move RDMA UAPI file to be under rdma/ folder, so whole responsibility
of syncing this file will be on them.

In kernel commit e1d2e8873369 ("IB/core: Add PCI write
end padding flags for WQ and QP"), we introduced new
device capability to advertise PCI write end padding.
PCI write end padding is the device's ability to pad the ending of
incoming packets (scatter) to full cache line such that the last
upstream write generated by an incoming packet will be a full cache
line.
This commit updates RDMAtool to present this field.

This patch adds ss-similar interface to view various resource
tracked objects. At this stage, only QP is presented.
1. Get all QPs for the specific device:
$ rdma res show qp link mlx5_4
link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib]
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]
$ rdma res show qp link mlx5_4/
link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib]
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]
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]

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.

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.
