net/mlx5e: Add some ethtool port control entries to the uplink rep netdev (2018-12-17 11:03:29 -0800)
----------------------------------------------------------------
mlx5-uplink-rep-2018-12-15
Or Gerlitz says:
This series is essentially a cleanup to align with the rest of the NIC switchdev drivers and make us
more robust and clear/n: currently the PF netdev serves as the mlx5 e-switch uplink netdev
representor when going into switchdev mode and back as plain NIC netdev when going out.
This causes some irregularities and misc troubles.
Move to use dedicated uplink rep, as we have for the VF vports.
The uplink rep netdev does has sysfs link and supports the sriov vf mac ndo, these two are in
use by libvirt and other orchestrators, It also has richer ethtool support to allow controlling the
port link & mtu along with supporting dcb and plugging into the mlx5 lag logic.

From: Or Gerlitz <[email protected]>
The reload of the IB interface done on the offloads stop call is redundant b/c we do that on mlx5_eswitch_disable_sriov(), remove it.

PATCH 2/9 net/mlx5e: Use single argument for the esw representor build params helper
In reply to Saeed MahameedFrom: Or Gerlitz <[email protected]>
This is prep step towards adding dedicated uplink representor.
The patch doesn't change any functionality.

PATCH 3/9 net/mlx5e: Use dedicated uplink vport netdev representor
In reply to Saeed MahameedFrom: Or Gerlitz <[email protected]>
Currently, when running in sriov switchdev mode, we are using the PF netdevice as the uplink representor, this is problematic from few aspects:
- will break when the PF isn't eswitch manager (e.g smart NIC env)
- misalignment with other NIC switchdev drivers
- makes us have and maintain special code, hurts the driver quality/robustness
- which in turn opens the door for future bugs
As of each and all of the above, we move to have a dedicated netdev representor for the uplink vport in a similar manner done for for the VF vports.
This includes the following:
1. have an uplink rep netdev as we have for VF reps
2. all reps use same load/unload functions
3. HW stats for uplink based on physical port counters and not vport counters
4. link state for the uplink managed through PAOS and not vport state
5. the uplink rep has sysfs link to the PF PCI function && uses the PF MAC address

PATCH 5/9 net/mlx5e: Uninstantiate esw manager vport netdev on switchdev mode
In reply to Saeed MahameedFrom: Or Gerlitz <[email protected]>
Now, when we have a dedicated uplink representor, the netdev instance set over the esw manager vport (PF) is of no-use. As such, remove it once we're on switchdev mode and get it back to life when off switchdev.
This is done by reloading the Ethernet interface as well (we already do that for the IB interface) from the eswitch code while going in/out of switchdev mode.
The Eth add/remove entries are modified to act differently when called in switchdev mode. In this case we only deal with registration of the eth vport representors. The rep netdevices are created from the eswitch call to load the registered eth representors.

PATCH 6/9 net/mlx5e: Handle port mtu/link, dcb and lag for uplink reps
In reply to Saeed MahameedFrom: Or Gerlitz <[email protected]>
Take care of setup/teardown for the port link, dcb, lag as well as dealing with port mtu and carrier for e-switch uplink representors.
This is achieved by adding a dedicated profile instance for uplink representors which includes the enable/disable and more profile routines which are invoked by the general mlx5e code for netdev attach/detach.

Some of the sriov ndo calls are needed also on the switchdev mode - e.g setup VF mac and reading vport stats. Add them to the uplink rep netdev ops. Same for the UDP tunnel ones, need them there to identify offloaded udp tunnel ports.
