5bacd77849 Revert "net: stmmac: enable multiple buffers"
The commit aff3d9eff843 ("net: stmmac: enable multiple buffers") breaks
numerous boards. while some patch exists for fixing some of it,
dwmac-sunxi is still broken with it.
Since this patch is very huge, it will be better to split it in smaller
part.

589a1a2e63 stmmac: use netif_set_real_num_{rx,tx}_queues
A driver must not access the two fields directly but should instead use
the helper functions to set the values and keep a consistent internal
state:

ethernet/stmicro/stmmac/stmmac_main.c: In function 'stmmac_dvr_probe':
ethernet/stmicro/stmmac/stmmac_main.c:4083:8: error: 'struct net_device' has no member named 'real_num_rx_queues'; did you mean 'real_num_tx_queues'?

270c7759fb net: stmmac: add set_mac to the stmmac_ops
Two different set_mac functions exists but stmmac_dwmac4_set_mac() is
only used for enabling and never for disabling.
So on dwmac4, the MAC RX/TX is never disabled.

This patch add a generic function pointer set_mac() to stmmac_ops and
replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to
this pointer.

Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops
is duplioacted like dwmac4_dma_ops.
