You might want to take a look at:

It seems to be asking the hardware about the phy mask.

Hi Andrew,
thanks a lot for the link. In the meantime I've understood the issue
better. It is due to the fact that the PHY is pin-strapped to address 1
and broadcast (at address 0) is enabled. The Micrel driver's
config_init() disables the broadcast and the PHY stops responding, which
causes the troubles. The kernel 3.17 didn't disable the broadcast and
therefore it worked.
I'm wondering how to solve or workaround this...
