Add support for devlink resource abstraction. The resources are
represented by a tree based structure and are identified by a name and
a size. Some resources can present their real time occupancy.
First the resources exposed by the driver can be observed, for example:
$devlink resource show pci/0000:03:00.0
pci/0000:03:00.0:
name kvd size 245760 unit entry
resources:
name linear size 98304 occ 0 unit entry size_min 0 size_max 147456 size_gran 128
name hash_double size 60416 unit entry size_min 32768 size_max 180224 size_gran 128
name hash_single size 87040 unit entry size_min 65536 size_max 212992 size_gran 128
Some resource's size can be changed. Examples:
$devlink resource set pci/0000:03:00.0 path /kvd/hash_single size 73088
$devlink resource set pci/0000:03:00.0 path /kvd/hash_double size 74368
The changes do not apply immediately, this can be validate by the 'size_new'
attribute, which represents the pending changed size. For example
$devlink resource show pci/0000:03:00.0
pci/0000:03:00.0:
name kvd size 245760 unit entry size_valid false
resources:
name linear size 98304 size_new 147456 occ 0 unit entry size_min 0 size_max 147456 size_gran 128
name hash_double size 60416 unit entry size_min 32768 size_max 180224 size_gran 128
name hash_single size 87040 unit entry size_min 65536 size_max 212992 size_gran 128
In case of a pending change the nested resources present an indication
for a valid configuration of its children (sum of its children sizes
doesn't exceed the parent's size).
In order for the changes to take place hot reload is needed. The hot
reload through devlink will be introduced in the following patch.

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

key action.
Possible values are enable/disable.

Add support for pipeline debug (dpipe). The headers are used both the
gain visibillity into the headers supported by the hardware, and to
build the headers/field database which is used by other commands.
Examples:
First we can see the headers supported by the hardware:
$devlink dpipe header show pci/0000:03:00.0
pci/0000:03:00.0:
name mlxsw_meta
field:
name erif_port bitwidth 32 mapping_type ifindex
name l3_forward bitwidth 1
name l3_drop bitwidth 1
Note that mapping_type is presented only if relevant. Also the header/
field id's are reported by the kernel they are not shown by default.
They can be observed by using the -v option. Also the headers scope
(global/local) is specified.
$devlink -v dpipe header show pci/0000:03:00.0
pci/0000:03:00.0:
name mlxsw_meta id 0 global false
field:
name erif_port id 0 bitwidth 32 mapping_type ifindex
name l3_forward id 1 bitwidth 1
name l3_drop id 2 bitwidth 1
Second we can examine the tables supported by the hardware. In order
to dump all the tables no table name should be provided:
$devlink dpipe table show pci/0000:03:00.0
In order to examine specific table its name have to be specified:
$devlink dpipe table show pci/0000:03:00.0 name erif
pci/0000:03:00.0:
name mlxsw_erif size 800 counters_enabled true
match:
type field_exact header mlxsw_meta field erif_port mapping ifindex
action:
type field_modify header mlxsw_meta field l3_forward
type field_modify header mlxsw_meta field l3_drop
To enable/disable counters on the table:
$devlink dpipe table set pci/0000:03:00.0 name erif counters enable
$devlink dpipe table set pci/0000:03:00.0 name erif counters disable
In order to see the current entries in the hardware for specific table:
$devlink dpipe table dump pci/0000:03:00.0 name erif
pci/0000:03:00.0:
index 0 counter 0
match_value:
type field_exact header mlxsw_meta field erif_port mapping ifindex mapping_value 383 value 0
action_value:
type field_modify header mlxsw_meta field l3_forward value 1
index 1 counter 0
match_value:
type field_exact header mlxsw_meta field erif_port mapping ifindex mapping_value 381 value 1
action_value:
type field_modify header mlxsw_meta field l3_forward value 1
In the above example the table contains two entries which does match
on erif port and forwards the packet or drop it (currently only the
forward count is implemented). The counter values are provided for
example. In case the counting is not enabled on the table the counters
will not be available.
