[Olsr-cvs] olsrd-current/src/win32 kernel_routes.c,1.26,1.27

[Bernd Petrovitsch]

Update of /cvsroot/olsrd/olsrd-current/src/win32
In directory sc8-pr-cvs3.sourceforge.net:/tmp/cvs-serv15735/src/win32

Modified Files:
	kernel_routes.c 
Log Message:
applied patch by Hannes Gredler <(spam-protected)>::

pls find attached a pointer for further CPU savings in olsrd.
even in large networks (>250 nodes) the avg. CPU utilization
does not get beyond 0.5% CPU load on standard 200Mhz WRT hardware.

patch from http://gredler.at/download/olsrd/rib2-refactoring4.diff

change-list:

- avoid the periodical rib-tree insertion

- add a FOR_ALL_HNA_RT_ENTRIES() macro for the snmp folks
    (or any parties who want to walk HNA entries).

- add an olsr_cnf option 'flat_fib_metrics' which defaults to TRUE.

   this is as per sven-olas request who has expressed concerns
   that the current flap-metric style is a bit unpleasant for troubleshooting.

   note that i have not yet added the cfg file parser routine for that -
   just the required tweaks in the change-processing FIB code.
