This series adds representor support for each rvu devices. When switchdev mode is enabled, representor netdev is registered for each rvu device. In implementation of representor model, one NIX HW LF with multiple SQ and RQ is reserved, where each RQ and SQ of the LF are mapped to a representor. A loopback channel is reserved to support packet path between representors and VFs. CN10K silicon supports 2 types of MACs, RPM and SDP. This patch set adds representor support for both RPM and SDP MAC interfaces. - Patch 1: Implements basic representor driver. - Patch 2: Add devlink support to create representor netdevs that can be used to manage VFs. - Patch 3: Implements basec netdev_ndo_ops. - Patch 4: Installs tcam rules to route packets between representor and VFs. - Patch 5: Enables fetching VF stats via representor interface - Patch 6: Adds support to sync link state between representors and VFs . - Patch 7: Enables configuring VF MTU via representor netdevs. - Patch 8: Adds representors for sdp MAC. - Patch 9: Adds devlink port support. - Patch 10: Implements offload stats. - Patch 11: Implements tc offload support. - patch 12: Adds documentation for rvu port representor. #devlink dev pci/0002:1c:00.0 Command to create PF/VF representor #devlink dev eswitch set pci/0002:1c:00.0 mode switchdev # ip link show Rpf1vf0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether f6:43:83:ee:26:21 brd ff:ff:ff:ff:ff:ff Rpf1vf1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 12:b2:54:0e:24:54 brd ff:ff:ff:ff:ff:ff Rpf1vf2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 4a:12:c4:4c:32:62 brd ff:ff:ff:ff:ff:ff Rpf1vf3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether ca:cb:68:0e:e2:6e brd ff:ff:ff:ff:ff:ff Rpf2vf0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 06:cc:ad:b4:f0:93 brd ff:ff:ff:ff:ff:ff ~# devlink port pci/0002:1c:00.0/0: type eth netdev Rpf1vf0 flavour physical port 0 splittable false pci/0002:1c:00.0/1: type eth netdev Rpf1vf1 flavour pcivf controller 0 pfnum 1 vfnum 1 external false splittable false pci/0002:1c:00.0/2: type eth netdev Rpf1vf2 flavour pcivf controller 0 pfnum 1 vfnum 2 external false splittable false pci/0002:1c:00.0/3: type eth netdev Rpf1vf3 flavour pcivf controller 0 pfnum 1 vfnum 3 external false splittable false ----------- v11:v1: - Submitted refactoring changes as a separate patch set. https://lore.kernel.org/netdev/20241023161843.15543-1-gakula@marvell.com/T/ - Moved documentation to a separate patch. - patch 9: Added code changes to forward updated mac address to VF. - Implemented TC offload support. v10-v11: - As suggested by "Jiri Pirko" adjusted the documentation. - Added more commit description to patch1. v9-v10: - Fixed build warning w.r.t documentation. v8-v9: - Updated the documentation. v7-v8: - Implemented offload stats ndo. - Added documentation. v6-v7: - Rebased on top net-next branch. v5-v6: - Addressed review comments provided by "Simon Horman". - Added review tag. v4-v5: - Patch 3: Removed devm_* usage in rvu_rep_create() - Patch 3: Fixed build warnings. v3-v4: - Patch 2 & 3: Fixed coccinelle reported warnings. - Patch 10: Added devlink port support. v2-v3: - Used extack for error messages. - As suggested reworked commit messages. - Fixed sparse warning. v1-v2: -Fixed build warnings. -Address review comments provided by "Kalesh Anakkur Purayil".
