Implement interface layer for the DCBNL subsystem. These are the functions to support the callbacks defined in the dcbnl_rtnl_ops struct. These callbacks are going to be used to interface with the DCB settings of the device. Implementation of dcb_nl set functions and supporting SW DCB functions.

Allow for rate limiting Tx queues. Bitrate is set in Mbps(megabits per second). Mbps max-rate is set for the queue via sysfs: /sys/class/net/<iface>/queues/tx-<queue>/tx_maxrate ex: echo 100 >/sys/class/net/ens7/queues/tx-0/tx_maxrate echo 200 >/sys/class/net/ens7/queues/tx-1/tx_maxrate Note: A value of zero for tx_maxrate means disabled, default is disabled.

DCB configuration flow needs to disable and enable only the PF (main) VSI, so use ice_ena_vsi and ice_dis_vsi. To avoid the use of ifdef to control the staticness of these functions, move them to ice_lib.c. Also replace the allocate and copy of old_cfg to kmemdup() in ice_pf_dcb_cfg().

Currently, we scan over all network namespaces at each received discovery message in order to check if the sending peer might be present in a host local namespaces. This is unnecessary since we can assume that a peer will not change its location during an established session. We now improve the condition for this testing so that we don't perform any redundant scans.

On 64bit arches, struct u64_stats_sync is empty and provides no help against load/store tearing. Using READ_ONCE()/WRITE_ONCE() would be needed. But the update side would be slightly more expensive. local64_t was defined so that we could use regular adds in a manner which is atomic wrt IRQs. However the u64_stats infra means we do not have to use local64_t on 32bit arches since the syncp provides the needed protection.

Changing a network device MTU can be a fairly frequent operation, and failure to change the MTU is reflected to user-space properly, both by an appropriate message as well as by looking at whether the device's MTU matches the configuration. Demote the prints to debug prints by using netdev_dbg(), making all Intel wired LAN drivers consistent, since they used a mixture of PCI device and network device prints before.

atlantic hardware does support UDP hardware segmentation offload. This allows user to specify one large contiguous buffer with data which then will be split automagically into multiple UDP packets of specified size. Bulk sending of large UDP streams lowers CPU usage and increases bandwidth.

Ido Schimmel says: ==================== mlxsw: Add layer 3 devlink-trap support This patch set from Amit adds support in mlxsw for layer 3 traps that can report drops and exceptions via devlink-trap. In a similar fashion to the existing layer 2 traps, these traps can send packets to the CPU that were not routed as intended by the underlying device. The traps are divided between the two types detailed in devlink-trap documentation: drops and exceptions. Unlike drops, packets received via exception traps are also injected to the kernel's receive path, as they are required for the correct functioning of the control plane. For example, packets trapped due to TTL error must be injected to kernel's receive path for traceroute to work properly. Patch set overview: Patch #1 adds the layer 3 drop traps to devlink along with their documentation. Patch #2 adds support for layer 3 drop traps in mlxsw. Patches #3-#5 add selftests for layer 3 drop traps. Patch #6 adds the layer 3 exception traps to devlink along with their documentation. Patches #7-#9 gradually add support for layer 3 exception traps in mlxsw. Patches #10-#12 add selftests for layer 3 exception traps. ==================== Signed-off-by: David S.
