net/sched: Add match-all classifier hw offloading.
Following the work that have been done on offloading classifiers like u32
and flower, now the match-all classifier hw offloading is possible. if
the interface supports tc offloading.
To control the offloading, two tc flags have been introduced: skip_sw and
skip_hw. Typical usage:
tc filter add dev eth25 parent ffff: \
matchall skip_sw \
action mirred egress mirror \
dev eth27
