2021-01-27net: allow user to set metric on default route learned via Router AdvertisementPraveen Chaudhary1-0/+10
For IPv4, default route is learned via DHCPv4 and user is allowed to change metric using config etc/network/interfaces. But for IPv6, default route can be learned via RA, for which, currently a fixed metric value 1024 is used. Ideally, user should be able to configure metric on default route for IPv6 similar to IPv4. This patch adds sysctl for the same. Logs: For IPv4: Config in etc/network/interfaces: auto eth0 iface eth0 inet dhcp metric 4261413864 IPv4 Kernel Route Table: $ ip route list default via 172.21.47.1 dev eth0 metric 4261413864 FRR Table, if a static route is configured: [In real scenario, it is useful to prefer BGP learned default route over DHCPv4 default route.] Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, P - PIM, E - EIGRP, N - NHRP, T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP, > - selected route, * - FIB route S>* 0.0.0.0/0 [20/0] is directly connected, eth0, 00:00:03 K 0.0.0.0/0 [254/1000] via 172.21.47.1, eth0, 6d08h51m i.e. User can prefer Default Router learned via Routing Protocol in IPv4.

2021-01-23mlxsw: Register physical ports as a devlink resourceDanielle Ratson1-0/+14
The switch ASIC has a limited capacity of physical ('flavour physical' in devlink terminology) ports that it can support. While each system is brought up with a different number of ports, this number can be increased via splitting up to the ASIC's limit. Expose physical ports as a devlink resource so that user space will have visibility to the maximum number of ports that can be supported and the current occupancy. In addition, add a "Generic Resources" section in devlink-resource documentation so the different drivers will be aligned by the same resource name when exposing to user space.

2021-01-20bonding: add a vlan+srcmac tx hashing optionJarod Wilson1-0/+13
This comes from an end-user request, where they're running multiple VMs on hosts with bonded interfaces connected to some interest switch topologies, where 802.3ad isn't an option. They're currently running a proprietary solution that effectively achieves load-balancing of VMs and bandwidth utilization improvements with a similar form of transmission algorithm. Basically, each VM has it's own vlan, so it always sends its traffic out the same interface, unless that interface fails. Traffic gets split between the interfaces, maintaining a consistent path, with failover still available if an interface goes down. Unlike bond_eth_hash(), this hash function is using the full source MAC address instead of just the last byte, as there are so few components to the hash, and in the no-vlan case, we would be returning just the last byte of the source MAC as the hash value. It's entirely possible to have two NICs in a bond with the same last byte of their MAC, but not the same MAC, so this adjustment should guarantee distinct hashes in all cases. This has been rudimetarily tested to provide similar results to the proprietary solution it is aiming to replace. A patch for iproute2 is also posted, to properly support the new mode there as well.

The CPTS clock is usually a clk-mux which allows to select CPTS reference clock by using 'assigned-clock-parents', 'assigned-clocks' DT properties. Also depending on integration the power-domains has to be specified to enable CPTS IP. Hence add 'assigned-clock-parents', 'assigned-clocks' and 'power-domains' properties to the CPTS DT bindings to avoid dtbs_check warnings: cpts@310d0000: 'assigned-clock-parents', 'assigned-clocks' do not match any of the regexes: 'pinctrl-[0-9]+' cpts@310d0000: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-01-13x86/xen: Add xen_no_vector_callback option to test PCI INTX deliveryDavid Woodhouse1-0/+4
It's useful to be able to test non-vector event channel delivery, to make sure Linux will work properly on older Xen which doesn't have it. It's also useful for those working on Xen and Xen-compatible hypervisors, because there are guest kernels still in active use which use PCI INTX even when vector delivery is available.

2021-01-08dt-bindings: net: dwmac-meson: use picoseconds for the RGMII RX delayMartin Blumenstingl1-6/+49
Amlogic Meson G12A, G12B and SM1 SoCs have a more advanced RGMII RX delay register which allows picoseconds precision. Deprecate the old "amlogic,rx-delay-ns" in favour of the generic "rx-internal-delay-ps" property. For older SoCs the only known supported values were 0ns and 2ns. The new SoCs have support for RGMII RX delays between 0ps and 3000ps in 200ps steps. Don't carry over the description for the "rx-internal-delay-ps" property and inherit that from ethernet-controller.yaml instead.
