linux-next-20170320 break stmmac on dwmac-sunxi

[Corentin Labbe]

Hello

Just pushed next-20170320 to my boards and stmmac stop working on both intree dwmac-sunxi and my dev dwmac-sun8i.
It seems that interrupts never fire, and transmit queue timeout.
I will try to bisect this problem but perhaps other people could try to reproduce it.
