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: Refactors and exports the shared service functions. - Patch 2: Implements basic representor driver. - Patch 3: Add devlink support to create representor netdevs that can be used to manage VFs. - Patch 4: Implements basec netdev_ndo_ops. - Patch 5: Installs tcam rules to route packets between representor and VFs. - Patch 6: Enables fetching VF stats via representor interface - Patch 7: Adds support to sync link state between representors and VFs . - Patch 8: Enables configuring VF MTU via representor netdevs. - Patch 9: Add representors for sdp MAC. - Patch 10: Add devlink port support.
