netgraph and high availability(bonding) problem

[amendola maurizio]

Hi at all
I have some problem to configure two network card in high availabilty mode.
I have done many test with some configurations but I desn't work. I have
Freebsd 5.2.1 and I have also add a patch realized from Evgeny Dolgopiat
about ng_one2many.c and ng_one2many.h. Test n.1 (with 2 cards on single
switch(yes, i know that is not a best ha solution) 
In this case I have had packets duplication but I have HA to get or put a
net cable. Test n2. (with 2 cards on differnet switch) In this case I have
not packets duplication but I haven't HA to get or put a net cable: if I get
a secondary cable It works but if I get the primary cable it doesn't work
all. This the configuration that I have testes:

#from README of ng_one2many patch

#Build ng_one2many module

#Assegno il nome xl0 al nodo o2m
ngctl name xl0: upper o2m

#Creo un link tra xl0 e o2m usando many0
ngctl connect xl0: o2m: lower many0

#Creo un link tra xl1 e o2m usando many1
ngctl connect xl1: o2m: lower many1

#Metto in promisc mode xl1
ngctl msg xl1: setpromisc 1

#Metto xl1 in autosrc=0
ngctl msg xl1: setautosrc 0

ifconfig xl0 inet 192.168.168.239 netmask 255.255.255.0

ngctl msg o2m: setconfig { xmitAlg=1 failAlg=2 } # set heartbit algo

ngctl msg o2m: sethbconfig { timeout=2 period=3 } # set time between
