[mpls-linux-general] Kernel debugging, multicast capability

[Yvan P. <yp...@cs...>]

Hi,

I would like to add the capability of your MPLS layer to forward packets
on several interfaces (multicast...). I have read the code and found that
the best way to do that was to add entries in the mii_instruction array in
your mpls_in_info structure. The length of this array would be 2*N where N
is the max number of interfaces to send the packet through instead of 2,
and I plan to add a loop in the mpls_input routine to duplicate the packet
and send it to several interfaces. Do you think this is the correct way to
handle the problem ?

Also, I have never coded inside the kernel, hence this (obvious) question:
what tool do you use to debug your code except printk ?

Thanks,

 Yvan
