Flower tests used to create ingress filter with specified parent qdisc
"parent ffff:" but dump them on "ingress". With recent commit that fixed
tcm_parent handling in dump those are not considered same parent anymore,
which causes iproute2 tc to emit additional "parent ffff:" in first line of
filter dump output. The change in output causes filter match in tests to
fail.
Prevent parent qdisc output when dumping filters in flower tests by always
correctly specifying "ingress" parent both when creating and dumping
filters.
Fixes: a7df4870d79b ("net_sched: fix tcm_parent in tc filter dump")

My commit simply restores the old behavior prior to 4.15, so are you
saying these tests never work correctly on kernels <= 4.15? If so,
they must be fixed no matter of my commit, right?
Thanks.

I think all of these tests are newer than 4.15.

You put "net-next" in your subject line but failed to include
netdev in the CC: list.
