Subject: [net-next PATCH v4 00/10] Introduce RVU representors
Date: Tue, 7 May 2024 22:09:11 +0530	[thread overview]
Message-ID: <20240507163921.29683-1-gakula@marvell.com> (raw)

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: 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.

Command to create VF representor
#devlink dev eswitch set pci/0002:1c:00.0 mode switchdev
VF representors are created for each VF when switch mode is set switchdev on representor PCI device
# devlink dev eswitch set pci/0002:1c:00.0  mode switchdev 
# ip link show
