We need to push the chain index down to the drivers, so they have the information to which chain the rule belongs. For now, no driver supports multichain offload, so only chain 0 is supported. This is needed to prevent chain squashes during offload for now. Later this will be used to implement multichain offload. Signed-off-by: NJiri Pirko <jiri@mellanox.com> Signed-off-by: NDavid S.

Tariq Toukan says: ==================== mlx4 drivers: version update This patchset contains version updates for the MLX4 drivers: Core, EN, and IB. Just like we've done in mlx5, we modify the outdated driver version (reported in ethtool for example). This better reflects the current driver state, and removes the redundant date string. We are not going to change this frequently or even use it. I include the IB patch in this series as it has similar subject and content. It does not cause any kind of conflict with Doug's tree. The rdma mailing list is CCed. Please let me know if I need to submit this differently. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Jakub Kicinski says: ==================== nfp: ctrl vNIC This series adds the ability to use one vNIC as a control channel for passing messages to and from the application firmware. The implementation restructures the existing netdev vNIC code to be able to deal with nfp_nets with netdev pointer set to NULL. Control vNICs are not visible to userspace (other than for dumping ring state), and since they don't have netdevs we use a tasklet for RX and simple skb list for TX queuing. Due to special status of the control vNIC we have to reshuffle the init code a bit to make sure control vNIC will be fully brought up (and therefore communication with app FW can happen) before any netdev or port is visible to user space. FW will designate which vNIC is supposed to be used as control one by setting _pf%u_net_ctrl_bar symbol. Some FWs depend on metadata being prepended to control message, some prefer to look at queue ID to decide that something is a control message. Our implementation can cater to both. First two users of this code will be eBPF maps and flower offloads. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

NFD ABI 0.5 is equivalent to NFD ABI 3.0 but requires that the driver checks the APP id symbol and makes sure it can support given app. Most advanced apps will likely require control vNIC (ability to exchange control messages between the driver and app FW). Detailed app version checking and capability exchange is left to app-specific code. Signed-off-by: NJakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We want to be able to create a special vNIC for control messages. This vNIC should be created before any netdev is registered to allow nfp_app logic to exchange messages with the FW app before any netdev is visible to user space. Unfortunately we can't enable IRQs until we know how many vNICs we will need to spawn. Divide the function which spawns netdevs for vNICs into three parts: - vNIC/memory allocation; - IRQ allocation; - netdev init and register. This will help us insert the initialization of the control channel after IRQ allocation but before netdev init and register.

Reading fw version from the BAR is trivial. Don't pass it around through layers of init functions, simply read it again where needed. This commit has the side effect of each vNIC having the exact NFD version from its own control memory, rather than all data vNICs assuming the version of the first one. This should not result in user-visible changes, though. Capabilities of data vNICs of trival apps are identical. Signed-off-by: NJakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: NDavid S.

Our open/close implementations have 3 stages: - allocation/freeing of ring resources, irqs etc., - device config, - device/stack enable (can't fail).

Russell King says: ==================== net: Add phylib support for MV88X3310 10G phy This patch series adds support for the Marvell 88x3310 PHY found on the SolidRun Macchiatobin board. The first patch introduces a set of generic Clause 45 PHY helpers that C45 PHY drivers can make use of if they wish. Patch 2 ensures that the Clause 22 aneg_done function will not be called for incompatible Clause 45 PHYs. Patch 3 fixes the aneg restart to be compatible with C45 PHYs - it can currently only cope with C22 PHYs. Patch 4 moves the "gen10g" driver into the Clause 45 code, grouping all core clause 45 code together. Patch 5 adds the phy_interface_t types for XAUI and 10GBase-KR links. As 10GBase-KR appears to be compatible with XFI and SFI, XFI and SFI, I currently see no reason to add XFI and SFI interface modes. There seems to be vendor code out there using these, but they all alias back to the same hardware settings. Patch 6 adds support for the MV88X3310 PHY, which supports both the copper and fiber interfaces. It should be noted that the MV88X3310 automatically switches its MAC facing interface between 10GBase-KR and SGMII depending on the negotiated speed. This was discussed with Florian, and we agreed to update the phy interface mode depending on the properties of the actual link mode to the PHY. v2: - update sysfs-class-net-phydev documentation - avoid genphy_aneg_done for non-C22 PHYs - expand comment about 0x30 constant - add comment about lack of reset - configure driver using MARVELL_10G_PHY ==================== Signed-off-by: NDavid S.

Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310). This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only supports Clause 45 accesses. The PHY appears (based on the vendor IDs) to be two different vendors IP, with each devad containing several instances. This PHY driver has only been tested with the RJ45 copper port, fiber port and a Marvell Armada 8040-based ethernet interface. It should be noted that to use the full range of speeds, MAC drivers need to also reconfigure the link mode as per phydev->interface, since the PHY automatically changes its interface mode depending on the negotiated speed.

XAUI allows XGMII to reach an extended distance by using a XGXS layer at each end of the MAC to PHY link, operating over four Serdes lanes. 10GBASE-KR is a single lane Serdes backplane ethernet connection method with autonegotiation on the link. Some PHYs use this to connect to the ethernet interface at 10G speeds, switching to other connection types when utilising slower speeds. 10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber modules.

GCC explicitly does not warn for unused static inline functions for -Wunused-function. The manual states: Warn whenever a static function is declared but not defined or a non-inline static function is unused. Clang does warn for static inline functions that are unused. It turns out that suppressing the warnings avoids potentially complex #ifdef directives, which also reduces LOC. Suppress the warning for clang.
