In FM10K, a single PCIe port can derive out a few logical ports, like SRIOV PF/VF devices, VMDQ objects. To better manage them, FM10K silicon assigns a Unique GLORT ID to each logical port. When a logical port sends a broadcast packet, the silicon will flood it to all logical ports, including the one that sent the broadcast packet. To prevent this, silicon has an rxq register to store the glort id of the logical port that queue binds to. FM10K has a switch core inside, which has a loopback suppression mechanism in the switch level. Switch level loopback suppression mostly works for the ether port traffic. This patch assigns a SGLORT for each RX queue, and enables PCIe port level loopback suppression. Signed-off-by: Shaopeng He <shaopeng.he@intel.com> Acked-by: Jing Chen <jing.d.chen@intel.com> |
