We can't get 'struct ofport_dpif *' because ofproto layer knows nothing
about 'ofport_dpif' structure. All that we can is to get 'struct ofport *'
and cast it.

Oh, copy-pasted typo. Thanks for pointing this. Fixed in fixup above.
I'll send v4 when the review of patch #3 will be finished.
Best regards, Ilya Maximets.
