[PATCH 1/2] eppic: vhost_net_buffers - Adopt to struct sk_buff changes

[Atsushi Kumagai]

Hello Kamalesh,

Thanks for taking care of the scripts.

The current scripts are created based on the same kernel version:

   ===================================
    Eppic scripts README
   ==================================
   
   The eppic scripts are based on the fedora 19 kernel. 

So if you update a part of the scripts, the target kernel version of
them will be complex and confusing.
I don't think we need to update these scripts since they are just sample,
the purpose is to tell users how to write a script.


Thanks,
Atsushi Kumagai
