[zebra 23003] BFD implementation with zebra

Hi all,

Now I implement BFD(Bi-directional Forwarding Detection) with linux
kernel-land software, which name is kbfd.
And I also prepared a patch for zebra-0.95a to control and synchronize
with kbfd.

Please check below page, and try kbfd.
#This is very very alpha release.
 It has a lot of problems, but it works.

  http://kbfd.sourceforge.net/

Currently, it is supported only ospfd, ospf6d, bgpd.

Usually, BFD is implemented on hardware like FPGA,
but kbfd is software implementation.
So, performance is not good(jitter, task scheduling).

But I think that BFD is a technology not only for rich router, but
also any network situation(PC to default-router, Wireless-Node, any
tunneled-communication).
That is my motivation for BFD software implementation.

All your feedback and comments would be appreciated.

regards,
