====================
mlxsw: implement port mirroring offload

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:

tc qdisc  add dev eth25 handle ffff: ingress
tc filter add dev eth25 parent ffff:            \
        matchall skip_sw                        \
        action mirred egress mirror             \
        dev eth27

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.
