Hi all, I use checksum-offloading for calculating the checksum of packets that i change/create inside my app. I use it for regular packets and for gre packets (on gre - the checksum is calculated on the outer-header).
On dpdk-16.07 everything works fine , But when i try to use that with DPDK-16.11 it seems that the offloading on GRE packets does not work (while on the regular packets it still works fine). In dpdk-16.07 I use the following flags on my mbuf to mark to the NIC that the packets need checksum calculation (m is the "struct rte_mbuf"): "m->ol_flags |= PKT_TX_OUTER_IPV4|PKT_TX_OUTER_IP_CKSUM;" On 16.11 I tried to add also the PKT_TX_TUNNEL_GRE (As i saw that addition in "csumonly.c" in the 16.11 version in the "pmd-test" app) - but that also didn't help. My NIC is : "Intel Corporation Ethernet Controller X710 for 10Gbe backplane" And i run my app in Ubuntu-14.0.4. Any Ideas? Thanks in advance - Eyal
