Tsirkin" , marcel@redhat.com Subject: [dpdk-dev] [PATCH v6 10/13] ixgbe: support VMDq RSS in non-SRIOV environment X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 09 Oct 2015 05:46:21 -0000 From: Changchun Ouyang In non-SRIOV environment, VMDq RSS could be enabled by MRQC register. In theory, the queue number per pool could be 2 or 4, but only 2 queues are available due to HW limitation, the same limit also exists in Linux ixgbe driver.
