Enumeration Type Documentation

anonymous enum

Enumerator
CE_GW_C_UNSPEC	Only a Dummy to skip index 0.
CE_GW_C_ECHO	Sends a message back. Calls ce_gw_nl_echo().
CE_GW_C_ADD	Add a gateway. Calls ce_gw_netlink_add().
CE_GW_C_DEL	Delate a gateway. Calls ce_gw_netlink_del().
CE_GW_C_LIST	list active gateways. Calls ce_gw_netlink_list().
__CE_GW_C_MAX	Maximum Number of Commands plus 1

Definition at line 58 of file netlink.h.

This enum are also defind in kernel in ce_gw_main.h

Enumerator
TYPE_NONE	No Type. Schould normally not used.
TYPE_ETH	Convert CAN Header to Ethernet Header
TYPE_NET	Copy complete CAN Frame into Ethernet payload. e.g use CAN als Network Layer (Layer 3) Protocol.
TYPE_TCP	Convert CAN Header into an IP/TCP Package
TYPE_UDP	Convert CAN Header into an IP/UDP Package
__TYPE_MAX	Maximum Type Number + 1
