int "Default radio transmission power"

help
TX power in dbm. Valid setting are: -18, -7, -4, -2, 0, 1, 2, 3, 5
If wrongly set, it will silently fail.

Number of re-transmission attempts radio driver should do, before
replying it could not send the packet (MAC PIB attribute:
macMaxFrameRetries).

help
Select which medium access protocol to use.
config NET_L2_IEEE802154_RADIO_CSMA_CA
bool "IEEE 802.15.4 unslotted CSMA-CA medium access protocol"
help
Use CSMA-CA mechanism (listen-before-talk with exponential backoff)
to transmit packets. This is the most common way of mediating radio
channel access and fits most usage scenarios (see IEEE 802.15.4-2020,
sections 6.2.5.1 and 10.2.8).
config NET_L2_IEEE802154_RADIO_ALOHA
bool "IEEE 802.15.4 Aloha medium access protocol (CCA mode 4)"
help
Use Aloha mechanism (send without any clear channel assessment) to
transmit packets. This is a simplistic way of transmitting packets
and fits low duty-cycle contexts where the radio spectrum is not
too heavily loaded (see IEEE 802.15.4-2020, section 10.2.8). The
current implementation does not randomize channel access.

The maximum number of backoffs the CSMA-CA algorithm will attempt
before declaring a channel access failure (MAC PIB attribute:
macMaxCSMABackoffs).

The minimum value of the backoff exponent (BE) in the CSMA-CA
algorithm (MAC PIB attribute: macMinBe). This setting must be less
than or equal NET_L2_IEEE802154_RADIO_CSMA_CA_MAX_BE.

The maximum value of the backoff exponent (BE) in the CSMA-CA
algorithm (MAC PIB attribute: macMaxBe).
