From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Add `rte_eth_dev_set_supported_ptypes` function that will allow the
application to inform the PMD the packet types it is interested in.
Based on the ptypes set PMDs can optimize their Rx path.

-If application doesn’t want any ptype information it can call
`rte_eth_dev_set_supported_ptypes(ethdev_id, RTE_PTYPE_UNKNOWN, NULL, 0)`
and PMD may skip packet type processing and set rte_mbuf::packet_type to
RTE_PTYPE_UNKNOWN.

-If application doesn’t call `rte_eth_dev_set_supported_ptypes` PMD can
return `rte_mbuf::packet_type` with `rte_eth_dev_get_supported_ptypes`.

-If application is interested only in L2/L3 layer, it can inform the PMD
to update `rte_mbuf::packet_type` with L2/L3 ptype by calling
`rte_eth_dev_set_supported_ptypes(ethdev_id,
		RTE_PTYPE_L2_MASK | RTE_PTYPE_L3_MASK, NULL, 0)`.

Hi,

looks good, just few comments below.

Many thanks for working on it,
Andrew.

When 0 is returned above, we should set set_ptypes. So, below
check num vs set_types should be done before callbacks check and
I think it is OK to do
       set_ptypes[0] = RTE_PTYPE_UNKNOWN;
just after the check. It will allow to simplify code below and will
make it set correctly even if 0 returned because of no callbacks.

I'd like to repeat my question about insufficient space to return
set_ptypes. Do we need to signal it somehow? If no, it should be
explained why in the comments here.

Please, take a look at promiscuous mode callback and let's put
more verbose description here which better document interface
to drivers. I think ptyep_mask description should refer to corresponding
defines to be used.
