Subject: linux-next: manual merge of the net-next tree with Linus' tree

Hi all,

Today's linux-next merge of the net-next tree got a conflict in
drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c between commit
64c3b252e9fc ("net: stmmac: fixed the pbl setting with DT") from the
tree and commit e2a240c7d3bc ("driver:net:stmmac: Disable DMA store and
forward mode if platform data force_thresh_dma_mode is set") from the
net-next tree.

I fixed it up (I think - see below) and can carry the fix as necessary (no
action is required).
