Most of the AX25 patches above are to be incorporated in a future kernel 
release.
They were discussed on netdev list and approved by Dave Miller.
There is on:y one that is not yet official, as it is very new and the 
bug it addresses is not yet completily solved.
However, like all others, its purpose is to remove causes of kernel 
panics or crash.
And it works.

By informing refered lists about these patches my goal was to help OMs 
having crash problems when using intensively AX25 applications.
They may safely upgrade to kernel.2.6.24.3 and use the patches provided.
You can also wait a month or two and you will have those patch included 
in kernel 2.6.25 or 2.6.26.

Other part of the patches are related to ROSE module and not yet in the 
future kernels cooker.
I built it after months of intensive experiments, in order to improve 
ROSE routing.
I submitted the patches for ROSE to linux development Netdev list and 
Ralf DL5RB.
I hope that most of them will be accepted for they give us good results 
with FPAC a packet router based on ROSE protocole.
