Merge branch 'cpsw-switchdev'Grygorii Strashko says:====================net: ethernet: ti: introduce new cpsw switchdev based driverThank you All for review of v6.There are no significant changes in this version, just fixed comments to v6.--- v6The major change in this version is DT bindings conversation to json-schema, andfixed other comments to v5. Also added patch to clean up ALE on init and netifrestart.--- v5The major part of work done in this iteration is rebasing on top of net-nextwith XDP series from Ivan Khoronzhuk [3], and enable XDP support in the newCPSW switchdev driver (it was little bit painful ;(). There are mostly nofunctional changes in new CPSW driver, just few fixes, sync with old driverand cleanups/optimizations. So, I've kept rest of cover letter unchanged.---This series originally based on work [1][2] done byIlias Apalodimas .This the RFC v5 which introduces new CPSW switchdev based driver which isoperating in dual-emac mode by default, thus working as 2 individualnetwork interfaces. The Switch mode can be enabled by configuring devlink driverparameter "switch_mode" to 1/true: devlink dev param set platform/48484000.switch \ name switch_mode value 1 cmode runtimeThis can be done regardless of the state of Port's netdev devices - UP/DOWN, butPort's netdev devices have to be in UP before joining the bridge to avoidoverwriting of bridge configuration as CPSW switch driver completely reloads itsconfiguration when first Port changes its state to UP.When the both interfaces joined the bridge - CPSW switch driver will startmarking packets with offload_fwd_mark flag unless "ale_bypass=0".All configuration is implemented via switchdev API.The previous solution of tracking both Ports joined the bridge(from netdevice_notifier) proved to be not correct as changing CPSW switchdriver mode required cleanup of ALE table and CPSW settings which happenswhile second Port is joined bridge and as result configuration loadedby bridge for the first Port became corrupted.The introduction of the new CPSW switchdev based driver (cpsw_new.c) is spliton two parts: Part 1 - basic dual-emac driver; Part 2 switchdev support.Such approach has simplified code development and testing alot. And, I hope,it will help with better review.patches #1 - 5: preparation patches which also moves common code to cpsw_priv.cpatches #6 - 9: Introduce TI CPSW switch driver based on switchdev and new DT bindingspatch #10: new CPSW switchdev driver documentationpatch #11: adds DT nodes for new CPSW switchdev driver added for DRA7 SoCpatch #12: adds DT nodes for new cpsw switchdev driver for am571x-idk boardpatch #13: enables build of TI CPSW driverMost of the contents of the previous cover-letter have been added innew driver documentation, so please refer to that for configuration,testing and future work.These patches can be found at (branch contains some additional patches requiredfor testing on top of net-next): https://github.com/grygoriyS/linux.git branch: lkml-5.4-switch-tbd-v7changes in v7: - patch 2: added check for devm_kmalloc_array() return value - patch 6: fixed commentschanges in v6: https://lkml.org/lkml/2019/11/9/108 - DT bindings converted to json-schema - netdev initialization is split on creation and registration. The netdevs registration happens now at the end of the pobe. - reworked cpsw_set_pauseparam() to use PHYlib APIs. - other comments for v5 fixedv5: https://patchwork.kernel.org/cover/11208785/ - rebase on top of net-next with XDP series from Ivan Khoronzhuk [3], and enable XDP support in the new CPSW switchdev driver cpsw driver (tested XDP_DROP only) - sync with old cpsw driver - implement comments from Ivan Khoronzhuk and Rob Herring - fixed "NETDEV WATCHDOG: .." warning after interface after interface UP/DOWN, missed TX wake in cpsw_adjust_link()v4: https://patchwork.kernel.org/cover/11010523/ - finished split of common CPSW code - added devlink support - changed CPSW mode configuration approach: from netdevice_notifier to devlink parameter - refactor and clean up ALE changes which allows to modify VLANs/MDBs entries - added missed support for port QDISC_CBS and QDISC_MQPRIO - the CPSW is split on two parts: basic dual_mac driver and switchdev support - added missed callback .ndo_get_port_parent_id() - reworked ingress frames marking in switch mode (offload_fwd_mark) - applied comments from Andrew Lunnv3: https://lwn.net/Articles/786677/Changes in v3:- alot of work done to split properly common code between legacy and switchdev CPSW drivers and clean up code- CPSW switchdev interface updated to the current LKML switchdev interface- actually new CPSW switchdev based driver introduced- optimized dual_mac mode in new driver. Main change is that in promiscuousmode P0_UNI_FLOOD (both ports) is enabled in addition to ALLMULTI (currentport) instead of ALE_BYPASS. So, port in non promiscuous mode will keeppossibility of mcast and vlan filtering.- changed bridge join sequnce: now switch mode will be enabled only whenboth ports joined the bridge. CPSW will be switched to dual_mac mode if anyport leave bridge. ALE table is completly cleared and then refiled whileswitching to switch mode - this simplidies code a lot, but introduces somelimitation to bridge setup sequence: ip link add name br0 type bridge ip link set dev br0 type bridge ageing_time 1000 ip link set dev br0 type bridge vlan_filtering 0 <- disable echo 0 > /sys/class/net/br0/bridge/default_vlan ip link set dev sw0p1 up <- add ports ip link set dev sw0p2 up ip link set dev sw0p1 master br0 ip link set dev sw0p2 master br0 echo 1 > /sys/class/net/br0/bridge/default_vlan <- enable ip link set dev br0 type bridge vlan_filtering 1 bridge vlan add dev br0 vid 1 pvid untagged self- STP tested with vlan_filtering 1/0. To make STP work I've had to set NO_SA_UPDATE for all slave ports (see comment in code). It also required to statically register STP mcast address {0x01, 0x80, 0xc2, 0x0, 0x0, 0x0};- allowed build both TI_CPSW and TI_CPSW_SWITCHDEV drivers- PTP can be enabled on both ports in dual_mac mode[1] https://patchwork.ozlabs.org/cover/929367/[2] https://patches.linaro.org/cover/136709/[3] https://patchwork.kernel.org/cover/11035813/====================Signed-off-by: David S.
