Just wondering if you got that merge right?  Here is the diff from what
I did yesterday to what you have in net-next:

diff --git a/drivers/net/ethernet/cadence/macb.c b/drivers/net/ethernet/cadence/macb.c
index f032e2a245b0..f00be585f661 100644

-	}
-
 	if (MACB_BFEXT(IDNUM, macb_readl(bp, MID)) == 0x2)
 		bp->caps |= MACB_CAPS_MACB_IS_GEM;
 
That section was removed by commit 421d9df0628b ("net/macb: merge
at91_ether driver into macb driver") and I presumed its effect was
moved into macb_probe().
