Hello,
With ixgbe driver, it seems mbuf packet_type is always 0 when vPMD code
(SSE) is enabled (tried 16.11 & master).
doc/guides/nics/ixgbe.rst seems a bit out of date, so I don't know if
this is expected or not.
When vPMD is disabled, either at compile time or runtime, the field is
correctly set.

It seems it is planned for 17.08, see:

indeed
I was mislead by rte_eth_dev_get_supported_ptypes() returning a non NULL
value
there is some logic to return NULL when vector mode is enabled, but the
code is only valid if rte_eth_dev_configure() was called before.
sorry for the noise
