Subject: [PATCH] fm10k: enable PCIe port level Loopback Suppression

A PCIe port may represent within it multiple logical ports
(for example when SR-IOV is enabled, or when a VMDQ type logical
port scheme is employed assigning ports to sets of queues).
For this reason each RX queue in each PCIe port is given a source
GLORT that is used for loopback suppression.
This patch assigns a SGLORT for each RX queue, and enables PCIe
port level Loopback Suppression.

The log message is a little obscure for me. Maybe you can wrote:
In FM10K, a single PF device can derive out a few logical ports, like SRIOV
VF device, VMDQ object. 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....
