Subject: [dpdk-users] TSO with Vmxnet3 driver

Hello Experts,
I am using VMXNET3 driver for one of the application i am developing, i was trying to enable TSO on vmxnet3 driver to send traffic out of the application. LRO enabled on ingress interface. On the TX interface (another vmxnet3) connected to different VDS, i enabled TSO offload. It is not working properly as expected as i am not sure how to get MSS value for the ingress flow.If i hard code MSS value it is fine but want to get right MSS value.

Since LRO is enabled on RX, I was expecting RX vmxnet3 interface should set MSS (m->tso_segsz to be valid) value in mbuf header and enable PKT_RX_LRO in ol_flags  but i see m->tso_segsz always Zero and PKT_RX_LRO not set in ol_flags.

Am i missing something? Any help would be appreciated. Thanks for your time.
Regards-Raja
