This patchset introduces tc matchall classifier and its offload
to Spectrum hardware. In combination with mirred action, defined port mirroring
setup is offloaded by mlxsw/spectrum driver.
The commands used for creating mirror ports:
# ingress mirroring using matchall
tc qdisc add dev eth25 handle ffff: ingress
tc filter add dev eth25 parent ffff: \
matchall skip_sw \
action mirred egress mirror \
dev eth27
# egress mirroring using matchall
tc qdisc add dev eth25 handle 1: root prio
tc filter add dev eth25 parent 1: \
matchall skip_sw \
action mirred egress mirror \
dev eth27
These patches contain:
- Resource query implementation
- Hardware port mirorring support for spectrum.
- Definition of the matchall traffic classifier.
- General support for hw-offloading for that classifier.
- Specific spectrum implementaion for matchall offloading.
