I believe the docs are not up to date.  I was struggling with this too
so I would like to suggest you to:
- turn the DEBUG on for dpdk related parts of OvS:
  ovs-appctl vlog/list <- to get the names of modules
  ovs-appctl vlog/set ...:dbg <- to set debug (e.g. dpdk:file:dbg and
netdef_dpdk:file:dbg)

I usually turn on file:dbg on all dpdk related modules (that you get
from the list) and 'tail -f' ovs-vswitchd.log to see what is going on.

You should see something like:
2018-11-23T11:18:02.186Z|00019|dpdk|INFO|DPDK Enabled - initialized

when DPDK gets initialized (this is INFO level so you don't have to
switch to debug - but I suggest it anyway when you are starting with DPDK).

Regards
Andrzej
