wireless network devices: Attach radio to d_buf before registering device to handle forwarding case.

When CONFIG_NET_IPFORWARD is enabled, and CONFIG_NET_6LOWPAN is being used, a packet that attempts to get forwarded on the 6LoWPAN interface will require that the radio's buffer be attached to d_buf. Otherwise the below exception will be hit.

~line 542 of sixlowpan_framelist.c

```
      /* Recover the reassembly buffer from the driver d_buf. */

      reass = (FAR struct sixlowpan_reassbuf_s *)radio->r_dev.d_buf;
      DEBUGASSERT(reass != NULL);
```

The underlying "radio" in this case is the mac802154_netdev.

This behavior has probably not been observed because the buffer is normally attached in the periodic txpoll worker. However, in my case, the 6LoWPAN interace was not UP yet, and therefore the worker hadn't run yet.

* sixlowpan: Fixes logic surrounding the Universal/Local bit. This bit represents whether the IID is locally/globally administered. The U/L bit is bit 1 of the MSB of the EUI-64. It should only be inverted in cases where there is a full EUI-64. In cases where the IID is derived from say, a short address, this bit should be forced to 0, indicating that it is locally administered.

6d93658ff8 Add new configuratin CONFIG_NET_MCASTGROUP. This option is selected automatically if either CONFIG_NET_IGMP or CONFIG_NET_MLD are selected. Most conditional logic based on CONFIG_NET_IGMP replaced with conditioning on CONFIG_NET_MCASTGROUP. 2018-10-31 15:03:51 -06:00

6a6bf1b62f :Remove CONFIG_NET_6LOWPAN_FRAMELEN. In this case where multiple radios are support3d, this may not be a constant. 6LoWPAN now always queries the driver to get the maximum frame length. 2017-09-10 11:40:54 -06:00

88a87f8e3f 6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started. 2017-08-26 10:00:47 -06:00
