Hello folks, I have a problem about using LRO. LRO offload is enabled, but the package cannot be coalesced.
I use dpdk 21.11, nic is hinic 1822.
enable LRO in rte_eth_dev_configure
conf->rxmode.offloads = DEV_RX_OFFLOAD_TCP_LRO | DEV_RX_OFFLOAD_TCP_CKSUM |DEV_RX_OFFLOAD_IPV4_CKSUM;
read pkts from rte_eth_rx_burst
pkts->ol_flags is 0x10180 have RTE_MBUF_F_RX_LRO, but pkts->pkt_len and kts->data_len is 1514. 1514 is single pkt max length, so it seems that there is no coalesced packets.
Client send pkt len is 8192.
What's wrong with me?
