cxgb4: add loopback ethtool self-test
In this test, loopback pkt is created and sent on default queue. The packet goes until the Multi Port Switch (MPS) just before the MAC and based on the specified channel number, it either goes outside the wire on one of the physical ports or looped back to Rx path by MPS. In this case, we're specifying loopback channel, instead of physical ports, so the packet gets looped back to Rx path, instead of getting transmitted on the wire. v3: - Modify commit message to include test details. v2: - Add only loopback self-test.
