From: Bodong Wang <bodong@xxxxxxxxxxxx> When sending TCP packets over RAW Ethernet QP with ibv_post_send, user has the option to set IBV_WR_TSO flag to enable large segment offload. The TSO header, header size and maximum segment size must be specified by the user through ibv_send_wr. Eligible hardware will break down large chunk of data into smaller segments per user setup. Error will be returned if TSO is not supported, or the size of chunk is too large for hardware to handle.
