I was modifying a packet in pktgen_pcap_mbuf_ctor()
and after modifying I wanted to offload the checksum calculation to h/w
so I am setting these flags in pktgen_pcap_mbuf_ctor function.
m->pkt.vlan_macip.f.l2_len = sizeof(struct ether_hdr);
m->pkt.vlan_macip.f.l3_len = sizeof(struct ipv4_hdr);
m->ol_flags = PKT_TX_IP_CKSUM
I even tried with setting .txq_flags = 0 in rte_eth_txconf struct in pktgen.c.
But still not able to get the h/w checksum. Am I missing anything ?
