Merge branch 'tc-testing-dnat-tuple-collision'

Marcelo Ricardo Leitner says:

====================
tc-testing: add test for ct DNAT tuple collision

That was fixed in 13c62f5371e3 ("net/sched: act_ct: handle DNAT tuple
collision").

For that, it requires that tdc is able to send diverse packets with
scapy, which is then done on the 2nd patch of this series.
