2017-05-25net-next: stmmac: rework the speed selectionLABBE Corentin
The current stmmac_adjust_link() part which handle speed have some if (has_platform) code and my dwmac-sun8i will add more of them. So we need to handle better speed selection. Moreover the struct link member speed and port are hard to guess their purpose. And their unique usage are to be combined for writing speed. So this patch replace speed/port by simpler speed10/speed100/speed1000/speed_mask variables. In dwmac4_core_init and dwmac1000_core_init, port/speed value was used directly without using the struct link. This patch convert also their usage to speedxxx.

2017-05-21net: ethernet: update drivers to make both SW and HW TX timestampsMiroslav Lichvar
Some drivers were calling the skb_tx_timestamp() function only when a hardware timestamp was not requested. Now that applications can use the SOF_TIMESTAMPING_OPT_TX_SWHW option to request both software and hardware timestamps, the drivers need to be modified to unconditionally call skb_tx_timestamp().

2017-04-13net: stmmac: set total length of the packet to be transmitted in TDES3Niklas Cassel
Field FL/TPL in register TDES3 is not correctly set on GMAC4. TX appears to be functional on GMAC 4.10a even if this field is not set, however, to avoid relying on undefined behavior, set the length in TDES3. The field has a different meaning depending on if the TSE bit in TDES3 is set or not (TSO). However, regardless of the TSE bit, the field is not optional. The field is already set correctly when the TSE bit is set. Since there is no limit for the number of descriptors that can be used for a single packet, the field should be set to the sum of the buffers contained in: [<desc with First Descriptor bit set> ... <desc n> ... <desc with Last Descriptor bit set>], which should be equal to skb->len.

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.
