From 0e98d5e6d9c365c82b264411057884cb1293c4e6 Mon Sep 17 00:00:00 2001 From: Chengchang Tang Date: Thu, 29 Oct 2020 20:51:52 +0800 Subject: [PATCH] net/hns3: fix packet type report in Rx Currently, hns3 supports recognizing a lot of ptypes, but most tunnel packet types are not reported to the API rte_eth_dev_get_supported_ptypes. And there are some errors in L2 and L3 packet recognition. The ARP and LLDP are classified to L3 field in RX descriptor. So, the ptype of LLDP and ARP packets will be set twice. And ptypes are assigned by bitwise OR, which will eventually cause the ptype result to be incorrect. Besides, when a packet with only L2 header, its ptype will not report by hns3 PMD. This is because the L2/L3 ptype table is not initialized properly. In this case, the table query result is 0 by default. As a result, it fixes missing supported ptypes and the mistake in L2/L3 packet recognition and the unreported L2 packet ptype by reporting its L2 type when the L3 type unrecognized..
