>
> 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 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.
