As the kemdup could return NULL, it should be better to check the return
value and return error if fails.
Moreover, the return value of prestera_acl_ruleset_keymask_set() should
be checked by cascade.

matchall rules can be added only to chain 0 and their priorities have
limitations:
- new matchall ingress rule's priority must be higher (lower value)
than any existing flower rule;
- new matchall egress rule's priority must be lower (higher value)
than any existing flower rule.
The opposite works for flower rule adding:
- new flower ingress rule's priority must be lower (higher value)
than any existing matchall rule;
- new flower egress rule's priority must be higher (lower value)
than any existing matchall rule.
This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.
To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.

Add support of rule offloading added to the non-zero index chain,
which was previously forbidden. Also, goto action is offloaded
allowing to jump for processing of desired chain.
Note that only implicit chain 0 is bound to the device port(s) for
processing. The rest of chains have to be jumped by actions.

Add user template explicit support. At this moment, max
TCAM rule size is utilized for all rules, doesn't matter
which and how much flower matches are provided by user. It
means that some of TCAM space is wasted, which impacts
the number of filters that can be offloaded.
Introducing the template, allows to have more HW offloaded
filters by specifying the template explicitly.
Example:
tc qd add dev PORT clsact
tc chain add dev PORT ingress protocol ip \
flower dst_ip 0.0.0.0/16
tc filter add dev PORT ingress protocol ip \
flower skip_sw dst_ip 1.2.3.4/16 action drop
NOTE: chain 0 is the default chain id for "tc chain" & "tc filter"
command, so it is omitted in the example above.
This patch adds only template support for default chain 0 suppoerted
by prestera driver at this moment. Chains are not supported yet,
and will be added later.

Add ACL infrastructure for Prestera Switch ASICs family devices to
offload cls_flower rules to be processed in the HW.
ACL implementation is based on tc filter api. The flower classifier
is supported to configure ACL rules/matches/action.
Supported actions:
- drop
- trap
- pass
Supported dissector keys:
- indev
- src_mac
- dst_mac
- src_ip
- dst_ip
- ip_proto
- src_port
- dst_port
- vlan_id
- vlan_ethtype
- icmp type/code
