State of coded PHY support in Zephyr 2.2

[BeckmaR]

Hey everyone,

I'm wondering about the support for the coded PHY aka BT long range in Zephyr 2.2. In general I only found this sample by nordic:
https://github.com/nrfconnect/sdk-nrf/tree/master/samples/bluetooth/peripheral_hr_coded
However, the nordic sdk is based on a newer zephyr version, and I am stuck to zephyr 2.2 due to it being BT SIG certified. The sample uses the following advertising parameters:

BT_LE_ADV_PARAM_INIT(BT_LE_ADV_OPT_CONNECTABLE |
				     BT_LE_ADV_OPT_EXT_ADV |
				     BT_LE_ADV_OPT_CODED,
				     BT_GAP_ADV_FAST_INT_MIN_2,
				     BT_GAP_ADV_FAST_INT_MAX_2,
				     NULL);

Sadly, BT_LE_ADV_OPT_CODED does not seem to exist in Zephyr 2.2. This leads me to believe that coded phy advertising is not fully supported in that version, and only came later. Is this assumption correct?
