From: Xiaoyun Wang Date: Tue, 17 Mar 2020 15:01:11 +0000 (+0800) Subject: net/hinic: fix LRO X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9d02f40d6503;p=dpdk.git net/hinic: fix LRO PMD driver should change the max_lro_pkt_size parameter into lro_wqe_num that used for hardware, and when packets are coalesced by hardware, PKT_RX_LRO flag should be set in the RX mbuf.
