MODS tests use private IOCTL to configure MAC loopback mode.
Add a priv ioctl handler to support this in nvethernet driver.
nvethernet driver also has a sysfs knob to configure loopback.

Issue:
1) MTL Queue can be in any order in input to DT. If not
initialized sw can crash.
2) Don't use return value of skb_get_queue_mapping as

Fix:
1) As MTL Queue sequence is already read, use it for
initialization and storing corresponding configuration.
2) Derive the channel number based on the q index
provided by skb_get_queue_mapping.

Issue: Tegra-eqos thermal cooling device is registered
during driver probe(). Once this registration is done,
callbacks via cooling_device_ops can be invoked at any time.
This implies even if driver is just probed, callbacks can try
to trigger a pad calibration due to temperature change and
result in failure trying to access MAC registers when the
MAC netdev interface is not up.
Fix: Move cooling device register/unregister to ether_open/
ether_close() routines respectively, so that callbacks can
be invoked only when interface is actually up.
