This patch removes handling to remove short address for a neigbour entry if RS/RA/NS/NA doesn't contain a short address. If these messages doesn't has any short address option, the existing short address from ndisc cache will be used. The current behaviour will set that the neigbour doesn't has a short address anymore.

When receiving neighbour information with short address option field we should check the complete range of invalid short addresses and set it to one invalid address setting which is the unspecified address. This address is also used when by creating at first a new neighbour entry to indicate no short address is set.

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.

This patch reworks the handling of compression/decompression of traffic class and flow label handling. The current method is hard to understand, also doesn't checks if we can read the buffer from skb length. I tried to put the shifting operations into static inline functions and comment each steps which I did there to make it hopefully somewhat more readable. The big mess to deal with that is the that the ipv6 header bring the order "DSCP + ECN" but iphc uses "ECN + DSCP". Additional the DCSP + ECN bits are splitted in ipv6_hdr inside the priority and flow_lbl[0] fields. I tested these compressions by using fakelb 802.15.4 driver and manipulate the tc and flow label fields manually in function "__ip6_local_out" before the skb will be send to lower layers. Then I looked up the tc and flow label fields in wireshark on a wpan and lowpan interface. Signed-off-by: NAlexander Aring <alex.aring@gmail.com> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

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.

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.
