I just went over all the patches and they mostly make sense to me. So
far the only point I'm uncertain of is the naming of the flag,
"fast_init". That is not clear on what it does and can be overloaded
with other stuff later and we probably don't want that.
Say, for example, we want percpu counters but to disable allocating
the stats for hw, to make the counter in 28169abadb08 ("net/sched: Add
hardware specific counters to TC actions") optional.
So what about:
TCA_ACT_FLAGS_NO_PERCPU_STATS
TCA_ACT_FLAGS_NO_HW_STATS (this one to be done on a subsequent patchset, yes)
?
