net/mlx5: E-Switch, let user to enable disable metadata 2021-04-14T18:02:26+00:00 Parav Pandit parav@nvidia.com 2020-10-30T20:44:16+00:00 7bf481d7e75a474e2a0f564b4de6bc2f1eeafc9a Currently each packet inserted in eswitch is tagged with a internal metadata to indicate source vport. Metadata tagging is not always needed. Metadata insertion is needed for multi-port RoCE, failover between representors and stacked devices. In many other cases, metadata enablement is not needed.

Currently each packet inserted in eswitch is tagged with a internal
metadata to indicate source vport. Metadata tagging is not always
needed. Metadata insertion is needed for multi-port RoCE, failover
between representors and stacked devices. In many other cases,
metadata enablement is not needed.

Metadata insertion slows down the packet processing rate of the E-switch
when it is in switchdev mode.

Below table show performance gain with metadata disabled for VXLAN
offload rules in both SMFS and DMFS steering mode on ConnectX-5 device.

----------------------------------------------
| steering | metadata | pkt size | rx pps    |

----------------------------------------------
| smfs     | disabled | 128Bytes | 42        |

----------------------------------------------
| dmfs     | enabled  | 128Bytes | 36        |
----------------------------------------------

Hence, allow user to disable metadata using driver specific devlink
parameter. Metadata setting of the eswitch is applicable only for the
switchdev mode.

Example to show and disable metadata before changing eswitch mode:
$ devlink dev param show pci/0000:06:00.0 name esw_port_metadata
pci/0000:06:00.0:
  name esw_port_metadata type driver-specific
    values:
      cmode runtime value true

$ devlink dev param set pci/0000:06:00.0 \
	  name esw_port_metadata value false cmode runtime

$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
