commit 4bbd4923d1f5627b0c47a9d7dfb5cc91224cfe0c upstream.

A user can change the operational GUID (a.k.a affective GUID) through
link/infiniband. Therefore it is preferred to return the currently set
GUID if it exists instead of the operational.

This way the PF can query which VF GUID will be set in the next bind.  In
order to align with MAC address, zero is returned if administrative GUID
is not set.

For example, before setting administrative GUID:
 $ ip link show
 ib0: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256
 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
 vf 0     link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff,
 spoof checking off, NODE_GUID 00:00:00:00:00:00:00:00, PORT_GUID 00:00:00:00:00:00:00:00, link-state auto, trust off, query_rss off

Then:

 $ ip link set ib0 vf 0 node_guid 11:00:af:21:cb:05:11:00
 $ ip link set ib0 vf 0 port_guid 22:11:af:21:cb:05:11:00

After setting administrative GUID:
 $ ip link show
 ib0: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256
 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
 vf 0     link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff,
 spoof checking off, NODE_GUID 11:00:af:21:cb:05:11:00, PORT_GUID 22:11:af:21:cb:05:11:00, link-state auto, trust off, query_rss off

Danit Goldberg says:

====================
This series extends RTNETLINK to provide IB port and node GUIDs, which
were configured for Infiniband VFs.

The functionality to set VF GUIDs already existed for a long time, and
here we are adding the missing "get" so that netlink will be symmetric and
various cloud orchestration tools will be able to manage such VFs more
naturally.

The iproute2 was extended too to present those GUIDs.

- ip link show &lt;device&gt;

For example:
- ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33
- ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10
- ip link show ib4
    ib4: &lt;BROADCAST,MULTICAST&gt; mtu 4092 qdisc noop state DOWN mode DEFAULT group default qlen 256
    link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
    vf 0     link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff,
    spoof checking off, NODE_GUID 22:44:33:00:33:11:00:33, PORT_GUID 10:21:33:12:00:11:22:10, link-state disable, trust off, query_rss off

<content type='text'>
Register "enable_roce" param, default value is RoCE enabled.
Current configuration is stored on mlx5_core_dev and exposed to user
through the cmode runtime devlink param.
Changing configuration requires changing the cmode driverinit devlink
param and calling devlink reload.

<content type='text'>
Instead of deciding a given device is virtual function or
not based on a device is PF or not, use already defined
MLX5_COREDEV_VF by introducing an helper API mlx5_core_is_vf().

This enables to clearly identify PF, VF and non virtual functions.

<content type='text'>
Move the device memory allocation and deallocation commands
SW ICM memory to mlx5_core to expose this API for all
mlx5_core users.

This comes as preparation for supporting SW steering in kernel
where it will be required to allocate and register device
memory for direct rule insertion.

In addition, an API to register this device memory for future
remote access operations is introduced using the create_mkey
commands.

<title>net/mlx5: Add HV VHCA infrastructure</title>

<content type='text'>
HV VHCA is a layer which provides PF to VF communication channel based on
HyperV PCI config channel. It implements Mellanox's Inter VHCA control
communication protocol. The protocol contains control block in order to
pass messages between the PF and VF drivers, and data blocks in order to
pass actual data.

The infrastructure is agent based. Each agent will be responsible of
contiguous buffer blocks in the VHCA config space. This infrastructure will
bind agents to their blocks, and those agents can only access read/write
the buffer blocks assigned to them. Each agent will provide three
callbacks (control, invalidate, cleanup). Control will be invoked when
block-0 is invalidated with a command that concerns this agent. Invalidate
callback will be invoked if one of the blocks assigned to this agent was
invalidated. Cleanup will be invoked before the agent is being freed in
order to clean all of its open resources or deferred works.

Block-0 serves as the control block. All execution commands from the PF
will be written by the PF over this block. VF will ack on those by
writing on block-0 as well. Its format is described by struct
mlx5_hv_vhca_control_block layout.

<content type='text'>
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

This cleans up a lot of unneeded code and logic around the debugfs
files, making all of this much simpler and easier to understand as we
don't need to keep the dentries saved anymore.
