If the used PHYs also support hardware timestamping, all configuration requests
should be forwared to the PHYs instead of being processed by the MAC driver
itself.

This enables PHY timestamping in combination with the cpsw driver.

Tested with an am335x based board with two DP83640 PHYs connected to the cpsw
switch.

Don't create eswitch QoS (root TSAR) on switch mode change. Create it on
first child TSAR object creation - vport or rate group. Keep track
root TSAR references and release root TSAR with last object deletion.
No need to check for QoS is enabled when installing tc matchall filter.
Remove related helper function due to no users of it.

Vports' QoS is not commonly used but consume SW/HW resources, which
becomes an issue on BlueField SoC systems.
Don't enable QoS on vports by default on eswitch mode change and enable
when it's going to be used by one of the top level users:
- configuring TC matchall filter with police action;
- setting rate with legacy NDO API;
- calling devlink ops->rate_leaf_*() callbacks.

Disable vport QoS on vport cleanup.

An eswitch vport of the devlink port is always enabled before a
devlink port is registered. And a eswitch vport is always disabled
after a devlink port is unregistered.
Hence avoid the vport enabled check in the devlink callback routine.
Such check is only applicable in the legacy SR-IOV callbacks.

There is a use case that the local and remote VTEPs are in the same
host. Currently, the out ifindex is not specified when looking up the
decap route for offloads. So in this case, a local route is returned
and the route dev is lo.

Actual tunnel interface can be created with a parameter "dev" [1],
which specifies the physical device to use for tunnel endpoint
communication. Pass this parameter to driver when looking up decap
route for offloads. So that a unicast route will be returned.
