To better manage them, FM10K > silicon assigned a Unique GLORT ID to each logical ports. > When a logical port sends a broadcast packet, the silicon will flood > it to all Logical ports, including the one sent the broadcast packet. > To prevent this, silicon has a rxq register to fill the glort id of > the logical port that queue binds to. > FM10K has a switch core inside, which has another 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. >=20 > Signed-off-by: Shaopeng He Acked-by : Jing Chen
