commit f97da3a546f9d6e1b858cfc45538a06b62396034
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Sun Jul 30 19:09:46 2017 -0600

    Network: Condition out some types that depend on definitions that are only available with 6LoWPAN is enabled.

commit 312e9dc1195527100e12bf6be8b629f5b29be1f6
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Sun Jul 30 18:57:23 2017 -0600

    6LoWPAN: Fix case where source and destination IP address were backward.  Fix some compile issues when star topology support is enabled.

commit 3b0e71c5807194fbb006d0560bb2c98133055ba3
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Sun Jul 30 16:01:48 2017 -0600

    6LoWPAN PktRadio:  Finishes up all logic; Lots of misc changes from build testing.

commit cc118f8cb335e1c48354fd7112e20be57de50b68
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Sun Jul 30 12:41:18 2017 -0600

    6LoWPAN: Remove explicate type struct ieee802154_frame_meta_s from derive interface methods.  Replace with a opaque void * type so that other radio meta data structures may use the interfaces.  Add a new radion interface to get properties of the radio.  Spirit:  Finish packet I/O interface with the network.

commit 1aa0a63e8341ca5f9f88c294f96d1740459146d4
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Sun Jul 30 07:57:15 2017 -0600

    6LoWPAN: Replace metadata input parameter type from struct ieee802154_data_ind_s to void*.  This permits radios with different MAC metadata to interact with 6LoWPAN.  Includes many changes to handle variable length radio addresses.  No longer just short and exteneded; any length.

commit 797d4adf7d41068c671f0217d369b797b269de1a
Author: Stefan Kolb <Stefan.Kolb@avat.de>
Date:   Fri Jul 28 09:19:04 2017 -0600

    We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.

    The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).

    The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.

* Input parameters:
* radio - Reference to a radio network driver state instance.
* metadata - Opaque reference to the radio-specific RX metadata.
* destaddr - The location in which to return the destination MAC address.
*
* Returned Value:
* Zero (OK) on success; a negated errno value on failure.
