bool "Enable CANBUS L2 layer [EXPERIMENTAL]"
depends on CAN_NET
select NET_6LO
help
Add a CANBUS L2 layer driver. This is the layer for IPv6 over CAN
(6loCAN). It uses IPHC to compress the IP header and ISO-TP for
flow control and reassembling.

config NET_L2_CANBUS_USE_FIXED_ADDR
bool "Use fixed L2 address"
help
Use a fixed L2 address for 6LoCAN instead of a random chosen one.

config NET_L2_CANBUS_DAD_RETRIES
int "Number of DAD retries"
default 5
help
Number of retries for Duplicate Address Detection.
Greater than one only makes sense for random link layer addresses.
config NET_L2_CANBUS_STMIN
int "STmin"
default 0
range 0 127
help
Minimal separation time between frames in ms.
The timer starts when the frame is queued and the next frame is
transmitted after expiration.
STmin is chosen by the receiver and transmitted in the FC
(Flow Control) frame. See also: ISO 15765-2:2016
config NET_L2_CANBUS_BS
int "BS (Block Size)"
default 8
range 0 256
help
Number of CF (Contiguous Frame) PDUs before next FC (Flow Control)
frame is sent. Zero value means all frames are sent consecutive
without an additional FC frame.
A BS counter at the sender counts from one to BS. When BS is reached,
the sender waits for a FC frame again an BS is reset.

config NET_L2_CANBUS_ETH_TRANSLATOR
bool "Enable 6LoCAN to Ethernet translator"
depends on NET_L2_ETHERNET
help
Enable a 6LoCAN Ethernet translator. With this translator it is
possible to connect a 6LoCAN network to a Ethernet network directly,
via a Switch or trough a router. Messages that goes through the
translator have a special address and the MAC address is carried inline.
The packet is forwarded with uncompressed IPv6 header.
