Add support for configuration parameters set and show.
Each parameter can be either generic or driver-specific.
The user can retrieve data on these configuration parameters by devlink
param show command and can set new value to a configuration parameter
by devlink param set command.
The configuration parameters can be set in different configuration
modes:
runtime - set while driver is running, no reset required.
driverinit - applied while driver initializes, requires restart
driver by devlink reload command.
permanent - written to device's non-volatile memory, hard reset
required to apply.
New commands added:
devlink dev param show [DEV name PARAMETER]
devlink dev param set DEV name PARAMETER value VALUE
cmode { permanent | driverinit | runtime }

Currently, calling 'ip xfrm monitor all' will
actually invoke the 'all-nsid' command because the
soft-match for 'all-nsid' occurs before the precise
match for 'all'. This patch rearranges the checks
so that the 'all' command, itself an alias for
invoking 'ip xfrm monitor' with no argument, can
be called consistent with the syntax for other ip
commands that accept an 'all'.

A recent commit changed rtnl_talk_* to return the response message in
allocated memory so callers need to free it. The change to name_is_vrf
did not save the device index which is pointing to a struct inside the
now allocated and freed memory resulting in garbage getting returned
in some cases.
Fix by using a stack variable to save the return value and only set
it to ifi->ifi_index after all checks are done and before the answer
buffer is freed.

The ip command would always lookup the network device index
even when not necessary. This slows down operations like creating
lots of VLAN's.
David reported the original issue, this is an alternative patch
that solves it in a slightly more general method.
Using iproute2 to create a bridge and add 4094 vlans to it can take from
2 to 3 *minutes*. The reason is the extraneous call to ll_name_to_index.
ll_name_to_index results in an ioctl(SIOCGIFINDEX) call which in turn
invokes dev_load. If the index does not exist, which it won't when
creating a new link, dev_load calls modprobe twice -- once for
netdev-NAME and again for NAME. This is unnecessary overhead for each
link create.
When ip link is invoked for a new device, there is no reason to
call ll_name_to_index for the new device. With this patch, creating
a bridge and adding 4094 vlans takes less than 3 *seconds*.

Currently NETNS_RUN_DIR is hardcoded and refers to /var/run/netns.
However, some systems (e.g. Android) doesn't have /var
which results in error attempts to create network namespaces on these
systems. This change makes NETNS_RUN_DIR configurable at build time
by allowing to pass environment variable to make command.
Also, this change makes /etc/netns directory configurable through
NETNS_ETC_DIR environment variable.
For example: ./configure && NETNS_RUN_DIR=/mnt/vendor/netns make
Tested: verified that iproute2 with configuration mentioned above
creates namespaces in /mnt/vendor/netns

Steve Wise says:
====================
This series enhances the iproute2 rdma tool to include displaying
driver-specific resource attributes. It is the user-space part of the
kernel driver resource tracking series that has been accepted for merging
into linux-4.18 [1]
If there are no additional review comments, it can now be merged, I think.
Changes since v2:
- resync rdma_netlink.h to fix uapi break
Changes since v1:
- commit log editorial fixes
- cite kernel commits that updated rdma_netlink.h in the
iproute2 commit syncing this header
- reorder stack definitions ala "reverse christmas tree"
- correctly handle unknown driver attributes when printing
Changes since v0/rfc:
- changed "provider" to "driver" based on kernel side changes
- updated man pages
- removed "RFC" tag
Thanks,
Steve.

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]

We make it easier for users to correlate between 128-bit node
identities and 32-bit node hash number by extending the 'node list'
command to also show the hash number.
We also improve the 'nametable show' command to show the node identity
instead of the node hash number. Since the former potentially is much
longer than the latter, we make room for it by eliminating the (to the
user) irrelevant publication key. We also reorder some of the columns so
that the node id comes last, since this looks nicer and is more logical.
