Subject: [dpdk-dev] pktgen offload checksum flag not able to make it work with pacp packets.
Date: Fri, 24 Jan 2014 10:54:36 -0800	[thread overview]
Message-ID: <CABkBM5G5T8pQFU_BwNS715ZM8Wqf_NGyEB+qx0NuE0YSym48RQ@mail.gmail.com> (raw)

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 ?



Thanks
Banashankar
