6lowpan: Don't set IFF_NO_QUEUE

2017-04-12T20:02:40Z

There is no point in setting IFF_NO_QUEUE should already have taken care of setting it if tx_queue_len is not set, in fact this may actually disable queue for interfaces that require it and do set tx_queue_len.

6lowpan: Set MAC address length according to LOWPAN_LLTYPE

2017-04-12T20:02:36Z

Set MAC address length according to the 6LoWPAN link layer in use. Bluetooth Low Energy uses 48 bit addressing while IEEE802.15.4 uses 64 bits. Signed-off-by: Patrik Flykt Reviewed-by: Stefan Schmidt Signed-off-by: Marcel Holtmann

6lowpan: introduce 6lowpan-nd

2016-06-16T03:41:23Z

This patch introduce different 6lowpan handling for receive and transmit NS/NA messages for the ipv6 neighbour discovery. The first use-case is for supporting 802.15.4 short addresses inside the option fields and handling for RFC6775 6CO option field as userspace option. Cc: David S.

6lowpan: remove ipv6 module request

2016-06-16T03:41:22Z

Since we use exported function from ipv6 kernel module we don't need to request the module anymore to have ipv6 functionality. Acked-by: Hannes Frederic Sowa Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: David S. Miller

6lowpan: add 802.15.4 short addr slaac

6lowpan: change naming for lowpan private data

2016-04-13T08:41:09Z

This patch changes the naming for interface private data for lowpan intefaces. The current private data scheme is: ------------------------------------------------- | 6LoWPAN Generic | LinkLayer 6LoWPAN | ------------------------------------------------- the current naming schemes are: - 6LoWPAN Generic: - lowpan_priv - LinkLayer 6LoWPAN: - BTLE - lowpan_dev - 802.15.4: - lowpan_dev_info the new naming scheme with this patch will be: - 6LoWPAN Generic: - lowpan_dev - LinkLayer 6LoWPAN: - BTLE - lowpan_btle_dev - 802.15.4: - lowpan_802154_dev Signed-off-by: Alexander Aring Reviewed-by: Stefan Schmidt Acked-by: Jukka Rissanen Signed-off-by: Marcel Holtmann

6lowpan: iphc: add support for stateful compression

2016-02-23T19:29:40Z

This patch introduce support for IPHC stateful address compression. It will offer the context table via one debugfs entry. This debugfs has and directory for each cid entry for the context table. Inside each cid directory there exists the following files: - "active": If the entry is added or deleted. The context table is original a list implementation, this flag will indicate if the context is part of list or not. - "prefix": The ipv6 prefix. - "prefix_length": The prefix length for the prefix. - "compression": The compression flag according RFC6775. This part should be moved into sysfs after some testing time. Also the debugfs entry contains a "show" file which is a pretty-printout for the current context table information.

6lowpan: fix debugfs interface entry name

2015-12-20T07:21:00Z

This patches moves the debugfs interface related register after netdevice register. The function lowpan_dev_debugfs_init will use "dev->name" which can be before register_netdevice a format string. The function register_netdevice will evaluate the format string if necessary and replace "dev->name" to the real interface name.

6lowpan: add debugfs support

2015-12-10T00:25:25Z

This patch will introduce a 6lowpan entry into the debugfs if enabled. Inside this 6lowpan directory we create a subdirectories of all 6lowpan interfaces to offer a per interface debugfs support. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: add lowpan dev register helpers

2015-12-10T00:25:25Z

This patch introduces register and unregister functionality for lowpan interfaces. While register a lowpan interface there are several things which need to be initialize by the 6lowpan subsystem. Upcoming functionality need to register/unregister per interface components e.g. debugfs entry. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann
