stmmac selftests currently use PHY loopback when a PHY is attached, and
fallback to MAC loopback otherwise. PHY loopback however isn't ideal nor
necessary for the tests we are running, that only stress the internal
stmmac features.

Some PHYs bring the carrier state down when in loopback mode, which will
prevent any packet transmission even for ourselves, making selftests
fail for non-stmmac related reasons.

Here is the summary with links:

  - [net-next,2/2] net: stmmac: Don't rely on the PHY for flow-control testing

You are awesome, thank you!
