the use of inter_module.c in a packet

Hi,

I’m not so sure (after reading the nddk) if I’m allowed to write into the
inter_module.c char array, or if there is any other system element that uses
it.
Anyone?

The use of this is not strictly defined. It’s a general
construct that allows a producer to pass info to a
convertor above / below it. For example, the ip stacks
currently pass the ip addr of the next hop where the
packet is going. The arp convertor module uses this
as the key to search its cache.

If you’re writing a convertor or protocol module, you’ll
have to agree on the form of the data passed. If you’re
writing a driver, don’t think you need it as you should
receive a fully formed packet ready to be put on the physical
layer.
