ACPI Device Specific Method (DSM) allows standardized feature configuration through the ACPI interface without the namespace pollution of the usual mechanism (ACPI method for each feature). Add generic function for evaluating DSM objects and function for evaluating a DSM with no arguments and a single int return value. also implement the required backport for UUID. Signed-off-by:

This patch adds a field to the tls rx offload context which enables drivers to force a send_resync call. This field can be used by drivers to request a resync at the next possible tls record. It is beneficial for hardware that provides the resync sequence number asynchronously. In such cases, the packet that triggered the resync does not contain the information required for a resync. Instead, the driver requests resync for all the following TLS record until the asynchronous notification with the resync request TCP sequence arrives. A following series for mlx5e ConnectX-6DX TLS RX offload support will use this mechanism. Signed-off-by:

Cong Wang says: ==================== net_sched: reduce the number of qdisc resets This patchset aims to reduce the number of qdisc resets during qdisc tear down. Patch 1~3 are preparation for their following patches, especially patch 2 and patch 3 add a few tracepoints so that we can observe the whole lifetime of qdisc's. Patch 4 and patch 5 are the ones do the actual work. Please find more details in each patch description. Vaclav Zindulka tested this patchset and his large ruleset with over 13k qdiscs defined got from 22s to 520ms. ==================== Signed-off-by: -

Resetting old qdisc on dev_queue->qdisc_sleeping in dev_qdisc_reset() is redundant, because this qdisc, even if not same with dev_queue->qdisc, is reset via qdisc_put() right after calling dev_graft_qdisc() when hitting refcnt 0. This is very easy to observe with qdisc_reset() tracepoint and stack traces. Reported-by:

Except for sch_mq and sch_mqprio, each dev queue points to the same root qdisc, so when we reset the dev queues with netdev_for_each_tx_queue() we end up resetting the same instance of the root qdisc for multiple times. Avoid this by checking the __QDISC_STATE_DEACTIVATED bit in each iteration, so for sch_mq/sch_mqprio, we still reset all of them like before, for the rest, we only reset it once. Reported-by:

RFC 6069 logic has been implemented for IPv4 only so far, right in the middle of tcp_v4_err() and was error prone. Move this code to one helper, to make tcp_v4_err() more readable and to eventually expand RFC 6069 to IPv6 in the future. Also perform sock_owned_by_user() check a bit sooner. Signed-off-by:

This patch adds support for offloading timestamping operations not only to the Ocelot switch (as already supported) but to compatible PHYs. When both the PHY and the Ocelot switch support timestamping operations, the PHY implementation is chosen as the timestamp will happen closer to the medium. Signed-off-by:

The ocelot core library is written with the idea in mind that the VLAN table is populated by the bridge. Otherwise, not even a sane default pvid is provided: in standalone mode, the default pvid is 0, and the core expects the bridge layer to change it to 1. So without this patch, the VLAN table is completely empty at the end of the commands below, and traffic is broken as a result: ip link add dev br0 type bridge vlan_filtering 0 && ip link set dev br0 up for eth in $(ls /sys/bus/pci/devices/0000\:00\:00.5/net/); do ip link set dev $eth master br0 ip link set dev $eth up done ip link set dev br0 type bridge vlan_filtering 1 Signed-off-by:

This patch reworks the MRP netlink interface. Before, each attribute represented a binary structure which made it hard to be extended. Therefore update the MRP netlink interface such that each existing attribute to be a nested attribute which contains the fields of the binary structures. In this way the MRP netlink interface can be extended without breaking the backwards compatibility. It is also using strict checking for attributes under the MRP top attribute. Signed-off-by:

Andrew Lunn says: ==================== Raw PHY TDR data Some ethernet PHYs allow access to raw TDR data in addition to summary diagnostics information. Add support for retrieving this data via netlink ethtool. The basic structure in the core is the same as for normal phy diagnostics, the PHY driver simply uses different helpers to fill the netlink message with different data. There is a graphical tool under development, as well a ethtool(1) which can dump the data as text and JSON. A patched ethtool(1) can be found in https://github.com/lunn/ethtool.git feature/cable-test-v5 Thanks for Chris Healy for lots of testing. v2: See the individual patches but: Pass distances in centimeters, not meters Allow the PHY to round distances to what it supports and report what it actually used along with the results. Make the Marvell PHY use steps a multiple of 0.805 meters, its native step size. v3: Move the TDR configuration into a structure Add a range check on step Use NL_SET_ERR_MSG_ATTR() when appropriate Move TDR configuration into a nest Document attributes in the request Unsquash the last two patches ==================== Signed-off-by:
