Function sparx5_tc_setup_qdisc_ets() always returns negative value
because it return -EOPNOTSUPP in the end. This patch returns the
rersult of sparx5_tc_ets_add() and sparx5_tc_ets_del() directly.

Use a tc matchall rule with a goto action to the VCAP specific chain to
enable the VCAP lookups.
If the matchall rule is removed the VCAP lookups will be disabled
again using its cookie as lookup to find the VCAP instance.
To enable the Sparx5 IS2 VCAP on eth0 you would use this command:
tc filter add dev eth0 ingress prio 5 handle 5 matchall \
skip_sw action goto chain 8000000
as the first lookup in IS2 has chain id 8000000

This adds initial TC flower filter support to Sparx5 for the IS2 VCAP.
The support consists of the source and destination MAC addresses,
and the trap and pass actions.
This is how you can create a rule that test the functionality:
tc qdisc add dev eth0 clsact
tc filter add dev eth0 ingress chain 8000000 prio 10 handle 10 \
protocol all flower skip_sw \
dst_mac 0a:0b:0c:0d:0e:0f \
src_mac 2:0:0:0:0:1 \
action trap
The IS2 chains in Sparx5 are assigned like this:
- chain 8000000: IS2 Lookup 0
- chain 8100000: IS2 Lookup 1
- chain 8200000: IS2 Lookup 2
- chain 8300000: IS2 Lookup 3

Add support for offloading ets qdisc to sparx5 switch.
The ets qdisc makes it possible to configure a mix og strict and
bandwidth-sharing bands. The ets qdisc must be attached as a root qdisc.

Add support for offloading tbf qdisc to sparx5 qdisc.
The tbf qdisc makes it possible to attach a shaper on traffic egressing
from a port or a queue. Per-port tbf qdiscs are attached as a root qdisc
directly and queue tbf qdiscs are attached to one of the classes of a
parent qdisc (such as mqprio).

Add support for offloading mqprio qdisc to sparx5 switch.
The offloaded mqprio qdisc currently does nothing by itself, but serves
as an attachment point for other qdiscs (tbf, ets etc.)
