Subin gave more information on the question:
Hello Didier,

Thanks for the fast response. Does IP/UDP profile always go together and
not just one of IP or UDP header compression alone? Please find below
more details.

Basically my question is if I can separate "transport layer(UDP)" header
compression from the "IP" header compression for the same packet. That
is, can I use the library to compress only the UDP header of the packet.
Then later use the library to compress the IP header of the same
compressed packet? In other words is it like IP/UDP together constitute
as a compression scheme/ profile or are the compression profiles
independent?

Just to give a background of why this is important for me is that I have
a channel with fixed transmission unit(136 byte). The compressed ROHC
packet has different sizes and padding with zeros to make a fixed
transmission unit is not efficient. So if its possible to separate the
compression schemes, I could do different processing at the transport
layer and the IP layer so that channel could be utilised fully.

Thanks,
Subin
