The problem is not a lots of filters, the problem is lots of classes and
therefore tcf
Both Eric and Paolo noticed the rcu_barrier() we use in
tcf_block_put_ext() could be a performance bottleneck when
we have lots of filters.
Paolo provided the following to demonstrate the issue:
tc qdisc add dev lo root htb
