Enrico Joerns 85b494c16b [doc] Give files a common structure by placing license first (partial) 
Followed by doxyen file and group tags.
This patch is only a first attempt to make provide a clean structure,
many more files require rework, too.

Adam Dunkels cff30a394b Merge pull request #635 from nfi/linkaddr-size 
Use LINKADDR_SIZE instead of sizeof(linkaddr_t) to avoid struct padding problems.

Niclas Finne b1335b08a8 Changed to use LINKADDR_SIZE instead of sizeof() to select between 
short address and long address as some platforms might use padding in
the struct. This fixes #555.
 2014-04-11 17:24:16 +02:00
Niclas Finne 68730566a3 Added method to framer that returns the header length if the framer 
would create a header with the current packet information.

This allows sicslowpan to calculate the max payload size without
consuming a sequence number or clearing/restoring the packet buffer.

Adam Dunkels 5b1a9f5bc2 Bugfix: when a packet is sent by the RDC layer, we should count the number of transmissions made because a single callback can pertain to multiple transmissions at the RDC layer. 2014-03-24 08:36:18 +01:00

Benoît Thébaudeau 4deba89f81 rdc: duplicate packets: Keep only the last sequence number for each address 
According to IEEE 802.15.4e (§6.4.3.9), in order to detect duplicate received
MAC-layer frames, only the most recently received frame's sequence number needs
to be stored for each unique device address. Doing so limits the possible false
duplicate packet detections to a single sequence number. This also allows to
keep the last sequence number of more device addresses for the same value of
MAX_SEQNOS.

Benoît Thébaudeau 477a4a7178 rdc: duplicate packets: Factor out detection code 
The code detecting duplicate packets in the RDC layer had been copied into most
RDC implementations. Factor it out into a new mac-sequence module in order to
have a single instance of this code.

Benoît Thébaudeau 14db3382af csma: Initialize sequence number with random value 
According to IEEE 802.15.4 (§5.1.6.1, §6.4.2), the MAC sequence numbers should
be initialized to random values. This was already the case in
framer-802154.c:create(), but not in csma.c:send_packet(), sometimes causing
false detections of duplicate MAC-layer packets in other devices when a device
was restarted too quickly. This patch decreases the probability of such an
event.
