X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" It looks like the cxgbe driver doesn't set the DEV_TX_OFFLOAD_MULTI_SEGS offload capability. However, it looks like sge.c does have support for sending mbuf chains, e.g. write_sgl(). Is this just an oversight or is there something fundamentally broken here?
