Value:

    void *key = teo_malloc(key_len); \
    size_t ptr = 0; \
    *(uint8_t*)key = rd->from_len; ptr += sizeof(uint8_t); \
    memcpy(key + ptr, rd->from, rd->from_len); ptr += rd->from_len; \
    *(uint16_t*)(key + ptr) = packet_num ; ptr += sizeof(packet_num); \
    *(uint16_t*)(key + ptr) = subpacket_num ; ptr += sizeof(subpacket_num)
