From: Pavan Nikhilesh Date: Thu, 7 Nov 2019 02:52:54 +0000 (+0530) Subject: net/octeontx2: support reduced set of packet types X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d2706e15e6fb;p=dpdk.git net/octeontx2: support reduced set of packet types Add support to set supported ptypes for octeontx2 and remove devarg scheme to disable ptype parsing support as application can use rte_eth_dev_set_ptypes() normative API to enable the same use case.
