+ * \brief Hwmp tag implements interaction between HWMP |
+ * protocol and MeshWifiMac |
+ * |
+ * \details Hwmp tag keeps the following: |
+ * 1. When packet is passed from Hwmp to 11sMAC: |
+ * - retransmitter address, |
+ * - TTL value, |
+ * 2. When packet is passed to Hwmp from 11sMAC: |
+ * - lasthop address, |
+ * - TTL value, |
+ * - metric value (metric of link is recalculated |
+ * at each packet, but routing table stores metric |
+ * obtained during path discovery procedure) |
