faf083f09d save copy of a rime address that points to a packet buffer, since the
packet buffer is cleared and overwritten before the address usage is done.

005578a722 added multihop routing support through replaceable modules. first implementation
uses rime's route discovery by translating between ipv6 and rime addresses.

8dbd2b2337 Significant power consumption optimization: LPP now keeps track of encounters with neighbors and uses this information to keep the radio switched off longer. 2009-04-03 19:59:22 +00:00

1425537a13 Introduced two garbage collection mode: greedy and reluctant.
The greedy GC mode attempts to erase as many sectors as possible, and
it is therefore a slow operation, since the flash driver must wait
for about a second after erasing one sector. The former behavior was
to always do a greedy GC if file reservations fails due to lack of space.

The new reluctant GC stops after erasing one sector, and therefore
we often do not have to wait if there is no file system operation
in the time while the sector is being erased. We call the garbage collector
using this mode when removing a file that is not a micro log file, since
the remove function is called recursively for micro log files that are
erased because the corresponding ordinary file is erased.

This change increases the coffee test (examples/sky/test-coffee.c) speed
from 9 to 5 seconds.

1d47e2a8da send immediate probes only if the packet is directed to us.
sleep for OFF_TIME if the queue is empty.

restrict double packet lifetime timeouts to unicast packets.

stop ctimer in remove_queued_packet in case the function is not called
via the ctimer callback. it could overwrite a valid packet otherwise.

dd082f7fcf improvements to lpp based on code from Adam and discussions with Thiemo.
* queue multiple packets
* send a strobe back immediately after receiving a data packet
* double the packet lifetime to allow for a missed probe
