f28c910274 devlink: Add devlink reload action and limit options
Add reload action and reload limit to devlink reload command to enable
the user to select the reload action required and constrains limits on
these actions that he may want to ensure.

The following reload actions are supported:
  driver_reinit: driver entities re-initialization, applying
                 devlink-param and devlink-resource values.
  fw_activate: firmware activate.

The uAPI is backward compatible, if the reload action option is omitted
from the reload command, the driver reinit action will be used.
Note that when required to do firmware activation some drivers may need
to reload the driver. On the other hand some drivers may need to reset
the firmware to reinitialize the driver entities. Therefore, the devlink
reload command returns the actions which were actually performed.

By default reload actions are not limited and driver implementation may
include reset or downtime as needed to perform the actions. However, if
reload limit is selected, the driver should perform only if it can do it
while keeping the limit constraints.

Reload limit added:
  no_reset: No reset allowed, no down time allowed, no link flap and no
            configuration is lost.

Command examples:
$devlink dev reload pci/0000:82:00.0 action driver_reinit
reload_actions_performed:
  driver_reinit

$devlink dev reload pci/0000:82:00.0 action fw_activate
reload_actions_performed:
  driver_reinit fw_activate

devlink dev reload pci/0000:82:00.1 action driver_reinit -jp
{
    "reload": {
        "reload_actions_performed": [ "driver_reinit" ]
    }
}

devlink dev reload pci/0000:82:00.0 action fw_activate -jp
{
    "reload": {
        "reload_actions_performed": [ "driver_reinit","fw_activate" ]
    }
}

0b1875cdc6 devlink: fix encap mode manupulation
DEVLINK_ATTR_ESWITCH_ENCAP_MODE netlink attribute carries enum. But the
code assumes bool value. Fix this by treating the encap mode in the same
way as other eswitch mode attributes, switching from "enable"/"disable"
to "basic"/"none", according to the enum. Maintain the backward
compatibility to allow user to pass "enable"/"disable" too. Also to be
in-sync with the rest of the "mode" commands, rename to "encap-mode".
Adjust the help and man page accordingly.

08e8e1ca3e devlink: extend reload command to add support for network namespace change
Extend existing devlink reload command by adding option "netns" by which
user can instruct kernel to reload the devlink instance into specified
network namespace.

Example:

$ ip netns add testns1
$ devlink dev reload netdevsim/netdevsim10 netns testns1

13925ae9eb devlink: Add param command support
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 }

d315b706e9 devlink: Add option to set and show eswitch encapsulation support
This is an e-switch global knob to enable HW support for applying
encapsulation/decapsulation to VF traffic as part of SRIOV e-switch offloading.

The actual encap/decap is carried out (along with the matching and other
actions) per offloaded e-switch rules, e.g as done when offloading the TC tunnel
key action.

Possible values are enable/disable.
