But on CNA devices, where multiple functions share same physical port. Here internal loopback test and external loopback test can be initiated by multiple functions at same time. To co exist all functions, firmware need to regulate what test can be run by which function. So before performing external loopback test, command need to send to firmware, which will quiescent other functions. User may not want to run external loopback test always. As special cable need to be connected for this test. So adding explicit flag in ethtool self test, which will specify interface to perform external loopback test.
