This patch, as indicated by git bisect, broke tc if there are multiple
actions specified. This somehow non-real life reproducer (the real case
where this broke for me was more complex) works fine with 732f03461bc4:

# tc filter add dev eth0 parent 1: matchall action vlan push id 1 action drop

while with both the current net-next and with e67aba559581, the result
is:

# tc filter add dev eth0 parent 1: matchall action vlan push id 1 action drop
Bad action type action
