TPR: Source Routing

For type DL_TPR devices, GLDv2 implements minimal support for source routing.

Source routing support includes the following tasks:

Source routing adds routing information fields to the MAC headers of outgoing packets. In addition, this support recognizes such fields in incoming packets.

GLDv2 source routing support does not implement the full route determination entity (RDE) specified in Section 9 of ISO 8802-2 (IEEE 802.2). However, this support can interoperate with any RDE implementations that might exist in the same or a bridged network.
