Re: Hi

Hi Satya,

I am not sure if I got your doubt.
The current ROHC channels which don't have any separate ROHC Protocol-ID
field have to use IP Protocol-ID in the under lying packets protocol
field. So, there can't be any mixup between ROHC and vanilla IP packets.
One has to use some out-of-band signalling to decide what has to be sent
(ROHC pkts, or IP pkts) but not both. 

Thanks & Regards
Biplab
