From: Rafal Kozik Date: Thu, 25 Jan 2018 15:27:43 +0000 (+0100) Subject: net/ena: do not set Tx L4 offloads in Rx path X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fd617795679019c7aea5ab1e8c85db02cf53f169;p=dpdk.git net/ena: do not set Tx L4 offloads in Rx path Information about received packet type detected by NIC should be stored in packet_type field of rte_mbuf. TX L4 offload flags should not be set in RX path. Only fields that could be set in of_flags during packet receiving are information if L4 and L3 checksum is correct.
