David Ahern says: ==================== net: Add address attribute to control metric of prefix route For use cases such as VRR (Virtual Router Redundancy) interface managers want efficient control over the order of prefix routes when multiple interfaces have addresses with overlapping/duplicate subnets. Currently, if two interfaces have addresses in the same subnet, the order of the prefix route entries is determined by the order in which the addresses are assigned or the links brought up. Any actions like cycling an interface up and down changes that order. This set adds a new attribute for addresses to allow a user to specify the metric of the prefix route associated with an address giving interface managers better and more efficient control of the order of prefix routes. Patches 1-3 refactor IPv6 address add functions to pass an ifa6_config struct. The functions currently have a long list of arguments and adding the metric just makes it worse. Because of the overall diff size in moving the arguments to a struct, the change is done in stages to make it easier to review starting with the bottom function and pushing the struct up to callers in each successive patch. Patch 4 introduces the new attribute. Patches 5 and 6 add support for the new attribute to IPv4 and IPv6 addresses. Patch 7 adds a set of test cases. Patch 8 adds support to iproute2 Changes since RFC - collapsed patches 1 and 3 into patch 2 - simplified stack variables in fib_modify_prefix_metric in patch 5 ==================== Signed-off-by:

So far, the PCI BAR0 register is used for triggering FW reset. However, that is a legacy attitude and it is recommended to use MRSR to perform reset instead. So do that. Move the reset into init() function as the cmd interface needs to be used. With that, IRQ initialization needs to be moved as well. As a side effect, the reset move simplifies the devlink reload flow. Signed-off-by:

Jakub Kicinski says: ==================== nfp: abm: RED/MQ qdisc offload This is second batch of advanced buffer management nfp driver changes. This series adds the qdisc offload. Support for a very simple subset of RED qdisc offload is added as needed for DCTCP ECN marking (min and max thresholds set to the same value). The first two patches fix glitches introduced by the previous series. We have to be careful about phys_port_name handling, because VFs share the same code path, and some user space may get confused by the names we chose. Since unlike previous offloads we can report the queue backlog both in bytes and packets we need to adjust how statistics are added up in the core (patch 6). There are some extra statistics we want to expose which don't fit into TC stats, namely counts of packets which have been fast- -forwarded without getting enqueued because there was no contention and number of packets that were ever queued (sum of all momentary backlogs). We expose those through ethtool stats (patches 8 and 9). Remaining 5 patches add MQ offload - to be able to set different configurations on different queues. Representors are made multi- -queue and we add offload support to MQ. MQ stats are added up before calling ->dump qdiscs on the children, and therefore don't include updated offload values. To avoid clearly incorrect stats MQ is made to also request stats update from offloads. This way we can correct the diff at the driver level. ==================== Signed-off-by:

MQ doesn't hold any statistics on its own, however, statistic from offloads are requested starting from the root, hence MQ will read the old values for its sums. Call into the drivers, because of the additive nature of the stats drivers are aware of how much "pending updates" they have to children of the MQ. Since MQ reset its stats on every dump we can simply offset the stats, predicting how stats of offloaded children will change. Signed-off-by:

mq offload is trivial, we just need to let the device know that the root qdisc is mq. Alternative approach would be to export qdisc_lookup() and make drivers check the root type themselves, but notification via ndo_setup_tc is more in line with other qdiscs. Note that mq doesn't hold any stats on it's own, it just adds up stats of its children. Signed-off-by:
