The VXLAN driver needs to differentiate between FDB entries learned by the VXLAN driver, and those added by the user. The latter ones shouldn't be taken over by external learning events. This is in accordance with bridge behavior. Therefore, extend the flags bitfield to 16 bits and add a new private NTF flag to mark the user-added entries. This seems preferable to adding a dedicated boolean, because passing the flag, unlike passing e.g. a true, makes it clear what the meaning of the bit is. Signed-off-by:

In a following patch, vxlan is extended to allow hardware FDB learning. For FDB entries learned this way, switchdev notifications should not be sent again, because the driver already knows about these entries. To that end, add an argument vxlan_fdb_notify() to determine whether the switchdev notifications should be sent. Propagate the argument to all call sites transitively, eventually passing true in all root calls. Signed-off-by:

This argument is necessary for vxlan_fdb_delete(), the API of which is prescribed by ndo_fdb_del, but __vxlan_fdb_delete() doesn't need it. Therefore drop it. Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2018-11-20 This series contains updates to the ice driver only. Akeem updates the driver to determine whether or not to do auto-negotiation based on the VSI state. Bruce cleans up the control queue code to remove duplicate code. Take advantage of some compiler optimizations by making some structures constant, and also note that they cannot be modified. Cleaned up formatting issues and code comment that needed clarification. Fixed a potential NULL pointer dereference by adding a check. Jaroslaw adds a check to verify if memory was allocated or not. Yashaswini Raghuram fixes the driver to ensure we are not enabling the LAN_EN flag if the MAC in the MAC-VLAN is a unicast MAC, so that the unicast packets are not forwarded to the wire. Dave fixes the return value of ice_napi_poll() to be more useful in returning the work that was done and should only return 0 when no work was done. Anirudh does code comment cleanup, to make more consistent. ==================== Signed-off-by: -

Merge branch 'dsa-microchip-Modify-KSZ9477-DSA-driver-in-preparation-to-add-other-KSZ-switch-drivers' Tristram Ha says: ==================== net: dsa: microchip: Modify KSZ9477 DSA driver in preparation to add other KSZ switch drivers This series of patches is to modify the original KSZ9477 DSA driver so that other KSZ switch drivers can be added and use the common code. There are several steps to accomplish this achievement. First is to rename some function names with a prefix to indicate chip specific function. Second is to move common code into header that can be shared. Last is to modify tag_ksz.c so that it can handle many tail tag formats used by different KSZ switch drivers. ksz_common.c will contain the common code used by all KSZ switch drivers. ksz9477.c will contain KSZ9477 code from the original ksz_common.c. ksz9477_spi.c is renamed from ksz_spi.c. ksz9477_reg.h is renamed from ksz_9477_reg.h. ksz_common.h is added to provide common code access to KSZ switch drivers. ksz_spi.h is added to provide common SPI access functions to KSZ SPI drivers. v4 - Patches were removed to concentrate on changing driver structure without adding new code. v3 - The phy_device structure is used to hold port link information - A structure is passed in ksz_xmit and ksz_rcv instead of function pointer - Switch offload forwarding is supported v2 - Initialize reg_mutex before use - The alu_mutex is only used inside chip specific functions v1 - Each patch in the set is self-contained - Use ksz9477 prefix to indicate KSZ9477 specific code ==================== Signed-off-by: -

ice_napi_poll is hard-coded to return zero when it's done. It should instead return the work done (if any work was done). The only time it should return zero is if an interrupt or poll is handled and no work is performed. So change the return value to be the minimum of work done or budget-1. Signed-off-by:

Extend cooling device with cooling levels vector to allow more flexibility of PWM setting. Thermal zone algorithm operates with the numerical states for PWM setting. Each state is the index, defined in range from 0 to 10 and it's mapped to the relevant duty cycle value, which is written to PWM controller. With the current definition fan speed is set to 0% for state 0, 10% for state 1, and so on up to 100% for the maximum state 10. Some systems have limitation for the PWM speed minimum. For such systems PWM setting speed to 0% will just disable the ability to increase speed anymore and such device will be stall on zero speed. Cooling levels allow to configure state vector according to the particular system requirements. For example, if PWM speed is not allowed to be below 30%, cooling levels could be configured as 30%, 30%, 30%, 30%, 40%, 50% and so on. Signed-off-by:

Under stress, softirq rx handler often hits a socket owned by the user, and has to queue the packet into socket backlog. When this happens, skb dst refcount is taken before we escape rcu protected region. This is done from __sk_add_backlog() calling skb_dst_force(). Consumer will have to perform the opposite costly operation. AFAIK nothing in tcp stack requests the dst after skb was stored in the backlog. If this was the case, we would have had failures already since skb_dst_force() can end up clearing skb dst anyway. Signed-off-by:

Jakub Kicinski says: ==================== gred: add offload support This series adds support for GRED offload in the nfp driver. So far we have only supported the RED Qdisc offload, but we need a way to differentiate traffic types e.g. based on DSCP marking. It may seem like PRIO+RED is a good match for this job, however, (a) we don't need strict priority behaviour of PRIO, and (b) PRIO uses the legacy way of mapping ToS fields to bands, which is quite awkward and limitting. The less commonly used GRED Qdisc is a better much for the scenario, it allows multiple sets of RED parameters and queue lengths to be maintained with a single FIFO queue. This is exactly how nfp offload behaves. We use a trivial u32 classifier to assign packets to virtual queues. There is also the minor advantage that GRED can't have its child changed, therefore limitting ways in which the configuration of SW path can diverge from HW offload. Last patch of the series adds support for (G)RED in non-ECN mode, where packets are dropped instead of marked. ==================== Signed-off-by: -

Original FW only allowed us to perform ECN marking. Newer releases also support plain old drop. Add the ability to configure drop policy. This is particularly useful in combination with GRED, because different bands can have different ECN marking setting. Signed-off-by:
