2017-01-24net: dummy: Introduce dummy virtual functionsPhil Sutter1-2/+215
The idea for this was born when testing VF support in iproute2 which was impeded by hardware requirements. In fact, not every VF-capable hardware driver implements all netdev ops, so testing the interface is still hard to do even with a well-sorted hardware shelf. To overcome this and allow for testing the user-kernel interface, this patch allows to turn dummy into a PF with a configurable amount of VFs. Since my patch series 'bus-agnostic-num-vf' has been accepted, implementing the required interfaces is pretty straightforward: Iff 'num_vfs' module parameter was given a value >0, a dummy bus type is being registered which implements the 'num_vf()' callback. Additionally, a dummy parent device common to all dummy devices is registered which sits on the above dummy bus. Joint work with Sabrina Dubroca.

In addition, add the necessary trap for sampled packets and integrate with matchall offloading to allow offloading of the sample tc action. The current offload support is for the tc command: tc filter add dev <DEV> parent ffff: \ matchall skip_sw \ action sample rate <RATE> group <GROUP> [trunc <SIZE>] Where only ingress qdiscs are supported, and only a combination of matchall classifier and sample action will lead to activating hardware packet sampling.

2017-01-24net: stmmac: dwmac-meson8b: make the RGMII TX delay configurableMartin Blumenstingl1-6/+14
Prior to this patch we were using a hardcoded RGMII TX clock delay of 2ns (= 1/4 cycle of the 125MHz RGMII TX clock). This value works for many boards, but unfortunately not for all (due to the way the actual circuit is designed, sometimes because the TX delay is enabled in the PHY, etc.). Making the TX delay on the MAC side configurable allows us to support all possible hardware combinations. This allows fixing a compatibility issue on some boards, where the RTL8211F PHY is configured to generate the TX delay. We can now turn off the TX delay in the MAC, because otherwise we would be applying the delay twice (which results in non-working TX traffic).

2017-01-23net: qcom/emac: rename emac_phy to emac_sgmii and move itTimur Tabi9-24/+23
The EMAC has an internal PHY that is often called the "SGMII". This SGMII is also connected to an external PHY, which is managed by phylib. These dual PHYs often cause confusion. In this case, the data structure for managing the SGMII was mis-named and located in the wrong header file. Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies to the internal PHY only. It also also moved from emac_phy.h (which supports the external PHY) to emac_sgmii.h (where it belongs). To keep the changes minimal, only the structure name is changed, not the names of any variables of that type. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S.

Saeed Mahameed says: ==================== mlx5 and mlx5e updates 2017-01-19 This series includes some updates for mlx5 core and mlx5e netdevice driver. From Leon, a small fix that remove an unnecessary print. From Eli Cohen, a fix to the FW version printout in case of internal error. From Eugenia Emantayev, two patches, the 1st adds mlx5 1pps (pulse per second) mlx5 infrastructure support and the 2nd adds the necessary bits for mlx5e ptp logic and structures. From Mohamad, add support for s-tagged packet receive when in promiscuous mode. Form Gal Pressman, MCAM (Management capabilities mask register) and PCAM (Ports capabilities mask register) registers infrastructure, those registers are needed in order to query the different statistics registers support in FW, in order for the driver to enable/disable query and reporting them back to user. On top of this infrastructure we've exposed new set of statistics groups: - MPCNT: Physical layer statistical counters (For symbol errors) - PPCNT: PCIe performance counters In addition to the statistics capabilities series we've moved the mlx5 HCA capabilities fields to a dedicated struct under the driver private data.

netdev_is_rx_handler_busy() check is a superset of netif_is_ipvlan_port() check and hence should be preferred. Signed-off-by: Mahesh Bandewar <maheshb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-01-20ipvlan: use netdev_is_rx_handler_busy instead of checking specific typeMahesh Bandewar1-2/+2
IPvlan checks if the master device is already used by checking a specific device (here it's macvlan device). This is technically not sufficient and it should just ensure the rx_handler is busy or not. This would be a super check that includes macvlan and any other that has already registered rx-handler.

2017-01-20cxgb4: hide unused warningsArnd Bergmann1-0/+2
The two new variables are only used inside of an #ifdef and cause harmless warnings when that is disabled: drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c: In function 'init_one': drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:9: error: unused variable 'port_vec' [-Werror=unused-variable] drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:4646:6: error: unused variable 'v' [-Werror=unused-variable] This adds another #ifdef around the declarations.

2017-01-19mlx4: support __GFP_MEMALLOC for rxEric Dumazet1-1/+2
Commit 04aeb56a1732 ("net/mlx4_en: allocate non 0-order pages for RX ring with __GFP_NOMEMALLOC") added code that appears to be not needed at that time, since mlx4 never used __GFP_MEMALLOC allocations anyway. As using memory reserves is a must in some situations (swap over NFS or iSCSI), this patch adds this flag. Note that this driver does not reuse pages (yet) so we do not have to add anything else.
