Please take a look at Documentation/networking/phy.txt and
Fixes: 529ed1275263 ("net: phy: phy drivers should not set SUPPORTED_[Asym_]Pause")

Pause frames / flow control

 The PHY does not participate directly in flow control/pause frames except by
 making sure that the SUPPORTED_Pause and SUPPORTED_AsymPause bits are set in
 MII_ADVERTISE to indicate towards the link partner that the Ethernet MAC
 controller supports such a thing. Since flow control/pause frames generation
 involves the Ethernet MAC driver, it is recommended that this driver takes care
 of properly indicating advertisement and support for such features by setting
 the SUPPORTED_Pause and SUPPORTED_AsymPause bits accordingly. This can be done
 either before or after phy_connect() and/or as a result of implementing the
 ethtool::set_pauseparam feature.
