2015-10-216lowpan: iphc: change define valuesAlexander Aring
This patch has the main goal to delete shift operations. Instead we doing masks and equals afterwards. E.g. for the SAM evaluation we masking only the SAM value which fits in iphc1 byte, then comparing with all possible SAM values over a switch case statement. We will not shifting the SAM value to somewhat readable anymore. Additional this patch slighty change the naming style like RFC 6282, e.g. TTL to HLIM and we will drop an errno now if CID flag is set, because we don't support it.

2015-10-216lowpan: cleanup lowpan_header_decompressAlexander Aring
This patch changes the lowpan_header_decompress function by removing inklayer related information from parameters. This is currently for supporting short and extended address for iphc handling in 802154. We don't support short address handling anyway right now, but there exists already code for handling short addresses in lowpan_header_decompress. The address parameters are also changed to a void pointer, so 6LoWPAN linklayer specific code can put complex structures as these parameters and cast it again inside the generic code by evaluating linklayer type before. The order is also changed by destination address at first and then source address, which is the same like all others functions where destination is always the first, memcpy, dev_hard_header, lowpan_header_compress, etc. This patch also moves the fetching of iphc values from 6LoWPAN linklayer specific code into the generic branch.

2015-10-216lowpan: cleanup lowpan_header_compressAlexander Aring
This patch changes the lowpan_header_compress function by removing unused parameters like "len" and drop static value parameters of protocol type. Instead we really check the protocol type inside inside the skb structure. Also we drop the use of IEEE802154_ADDR_LEN which is link-layer specific. Instead we using EUI64_ADDR_LEN which should always the default case for now.

2015-10-086lowpan: move shared settings to lowpan_netdev_setupAlexander Aring
This patch moves values for all lowpan interface to the shared implementation of 6lowpan. This patch also quietly fixes the forgotten IFF_NO_QUEUE flag for the bluetooth 6LoWPAN interface. An identically commit is 4afbc0d ("net: 6lowpan: convert to using IFF_NO_QUEUE") which wasn't changed for bluetooth 6lowpan. All 6lowpan interfaces should be virtual with IFF_NO_QUEUE, using EUI64 address length, the mtu size is 1280 (IPV6_MIN_MTU) and the netdev type is ARPHRD_6LOWPAN.

2015-09-22ieee802154: change needed headroom/tailroomAlexander Aring
This patch cleanups needed_headroom, needed_tailroom and hard_header_len fields for wpan and lowpan interfaces. For wpan interfaces the worst case mac header len should be part of needed_headroom, currently this is set as hard_header_len, but hard_header_len should be set to the minimum header length which xmit call assumes and this is the minimum frame length of 802.15.4. The hard_header_len value will check inside send callbacl of AF_PACKET raw sockets. For lowpan interfaces, if fragmentation isn't needed the skb will call dev_hard_header for 802154 layer and queue it afterwards. This happens without new skb allocation, so we need the same headroom and tailroom lengths like 802154 inside 802154 6lowpan layer. At least we assume as minimum header length an ipv6 header size.

This patch moves module_init of 6lowpan module into core functionality of 6lowpan module. To load the ipv6 module at probing of the 6lowpan module should be core functionality. Loading next header compression modules is iphc specific. Nevertheless we only support IPHC for the generic 6LoWPAN branch right now so we can put it into the core functionality.

2015-08-116lowpan: add generic 6lowpan netdev private dataAlexander Aring
This patch introduced the 6lowpan netdev private data struct. We name it lowpan_priv and it's placed at the beginning of netdev private data. All lowpan interfaces should allocate this room at first of netdev private data. 6LoWPAN LL private data can be allocate by additional netdev private data, e.g. dev->priv_size should be "sizeof(struct lowpan_priv) + sizeof(LL_LOWPAN_PRIVATE_DATA)".

2015-08-106lowpan: Fix extraction of flow label fieldLukasz Duda

To decompress the first byte of the Flow Label when the TF flag is set to 0x01, the second half of the first byte is needed. The patch fixes the extraction of the Flow Label field.

This patch moves generic code which is used by bluetooth and ieee802154 6lowpan to a new net/6lowpan directory. This directory contains generic 6LoWPAN code which is shared between bluetooth and ieee802154 MAC-Layer. This is the IPHC - "IPv6 Header Compression" format at the moment. Which is described by RFC 6282 [0]. The BLTE 6LoWPAN draft describes that the IPHC is the same format like IEEE 802.15.4, see [1]. Futuremore we can put more code into this directory which is shared between BLTE and IEEE 802.15.4 6LoWPAN like RFC 6775 or the routing protocol RPL RFC 6550.
