devlink: Support setting max_io_eqs
Many devices send event notifications for the IO queues,
such as tx and rx queues, through event queues.
Enable a privileged owner, such as a hypervisor PF, to set the number
of IO event queues for the VF and SF during the provisioning stage.
example:
Get maximum IO event queues of the VF device::
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
function:
hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 10
Set maximum IO event queues of the VF device::
$ devlink port function set pci/0000:06:00.0/2 max_io_eqs 32
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1

devlink: Expose port function commands to control IPsec packet offloads
Expose port function commands to enable / disable IPsec packet offloads,
this is used to control the port IPsec capabilities.
When IPsec packet is disabled for a function of the port (default),
function cannot offload IPsec packet operations (encapsulation and XFRM
policy offload). When enabled, IPsec packet operations can be offloaded
by the function of the port, which includes crypto operation
(Encrypt/Decrypt), IPsec encapsulation and XFRM state and policy
offload.
Example of a PCI VF port which supports IPsec packet offloads:
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0

devlink: Expose port function commands to control migratable
Expose port function commands to enable / disable migratable
capability, this is used to set the port function as migratable.
Live migration is the process of transferring a live virtual machine
from one physical host to another without disrupting its normal
operation.
In order for a VM to be able to perform LM, all the VM components must
be able to perform migration. e.g.: to be migratable.
In order for VF to be migratable, VF must be bound to VFIO driver with
migration support.
When migratable capability is enabled for a function of the port, the
device is making the necessary preparations for the function to be
migratable, which might include disabling features which cannot be
migrated.
Example of LM with migratable function configuration:
Set migratable of the VF's port function.
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
function:
hw_addr 00:00:00:00:00:00 migratable disable
$ devlink port function set pci/0000:06:00.0/2 migratable enable
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
function:
hw_addr 00:00:00:00:00:00 migratable enable
Bind VF to VFIO driver with migration support:
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/unbind
$ echo mlx5_vfio_pci > /sys/bus/pci/devices/0000:08:00.0/driver_override
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/bind
Attach VF to the VM.
Start the VM.
Perform LM.

devlink: Expose port function commands to control RoCE
Expose port function commands to enable / disable RoCE, this is used to
control the port RoCE device capabilities.
When RoCE is disabled for a function of the port, function cannot create
any RoCE specific resources (e.g GID table).
It also saves system memory utilization. For example disabling RoCE enable a
VF/SF saves 1 Mbytes of system memory per function.
Example of a PCI VF port which supports function configuration:
Set RoCE of the VF's port function.
