2017-03-28stmmac: use netif_set_real_num_{rx,tx}_queuesArnd Bergmann
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'?

2017-03-24net: stmmac: add set_mac to the stmmac_opsLABBE Corentin
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. Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: David S.

2017-03-22net: stmmac: Restore DT backwards-compatibilityThierry Reding
Recent changes to support multiple queues in the device tree bindings resulted in the number of RX and TX queues to be initialized to zero for device trees not adhering to the new bindings. Restore backwards-compatibility with those device trees by falling back to a single RX and TX queues each.
