Hello All,

Thanks for taking the time to look into this. I will submit a patch later 
today, it's literally a one line change. I was looking into the OF1.3 spec and 
if I understand this correctly, I can't mix and match oxm and nxm fields 
because of the experimenter flag at the beginning of the OF header. If I need 
to do a IP header match on nw_src, nw_dst and nw_ttl, I would also need entries 
in oxm_fields to handle the NXM_OF_IP_SRC and NXM_OF_IP_DST code points. 

I could add those and test them before I submit the patch if anyone else needs 
it.

Thank you, 
-(James) Shridatt Sugrim

Hi Fujita-San,

Either is fine.
Because now we are testing the patch for the other missing OXMs including 
NXM_NX_IP_TTL.
We will post it in a few days.

Thanks,
Iwase
