+	tristate "CAN bus subsystem support"
+	select SKB_EXTENSIONS
+	help
+	  Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial
+	  communications protocol. Development of the CAN bus started in
+	  1983 at Robert Bosch GmbH, and the protocol was officially
+	  released in 1986. The CAN bus was originally mainly for automotive,
+	  but is now widely used in marine (NMEA2000), industrial, and medical
+	  applications. More information on the CAN network protocol family
+	  PF_CAN is contained in <Documentation/networking/can.rst>.
+
+	  If you want CAN support you should say Y here and also to the
+	  specific driver for your controller(s) under the Network device
+	  support section.

+config CAN_RAW
+	tristate "Raw CAN Protocol (raw access with CAN-ID filtering)"
+	default y
+	help
+	  The raw CAN protocol option offers access to the CAN bus via
+	  the BSD socket API. You probably want to use the raw socket in
+	  most cases where no higher level protocol is being used. The raw
+	  socket has several filter options e.g. ID masking / error frames.
+	  To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW.
+
+config CAN_BCM
+	tristate "Broadcast Manager CAN Protocol (with content filtering)"
+	default y
+	help
+	  The Broadcast Manager offers content filtering, timeout monitoring,
+	  sending of RTR frames, and cyclic CAN messages without permanent user
+	  interaction. The BCM can be 'programmed' via the BSD socket API and
+	  informs you on demand e.g. only on content updates / timeouts.
+	  You probably want to use the bcm socket in most cases where cyclic
+	  CAN messages are used on the bus (e.g. in automotive environments).
+	  To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM.
+
+config CAN_GW
+	tristate "CAN Gateway/Router (with netlink configuration)"
+	default y
+	help
+	  The CAN Gateway/Router is used to route (and modify) CAN frames.
+	  It is based on the PF_CAN core infrastructure for msg filtering and
+	  msg sending and can optionally modify routed CAN frames on the fly.
+	  CAN frames can be routed between CAN network interfaces (one hop).
+	  They can be modified with AND/OR/XOR/SET operations as configured
+	  by the netlink configuration interface known e.g. from iptables.

+	tristate "ISO 15765-2 CAN transport protocol"
+	help
+	  CAN Transport Protocols offer support for segmented Point-to-Point
+	  communication between CAN nodes via two defined CAN Identifiers.
+	  This protocol driver implements segmented data transfers for CAN CC
+	  (aka Classical CAN, CAN 2.0B) and CAN FD frame types which were
+	  introduced with ISO 15765-2:2016.
+	  As CAN frames can only transport a small amount of data bytes
+	  (max. 8 bytes for CAN CC and max. 64 bytes for CAN FD) this
+	  segmentation is needed to transport longer Protocol Data Units (PDU)
+	  as needed e.g. for vehicle diagnosis (UDS, ISO 14229) or IP-over-CAN
+	  traffic.
