"ptype_mask" is the list of ptypes that we are interested right, having it 0
means we are not interested with any. But using "ptype_mask" as mask in
'rte_eth_dev_get_supported_ptypes()' will cause this API return 0 and it will
fails this command.
Why not use 'RTE_PTYPE_ALL_MASK' as mask value?

I am not sure about this command, we have now capability to set/disable ptypes
on demand, why disabling them by default?
