Hello,

For synchronous network interfaces, besides configuring network parameters
such as IP address, netmask, MTU, etc., the system should also configure
parameters specific to these sync i/f's, such as media (e.g V.35, X.21,
T1, E1), clock (internal or external, and value if int.), protocol (e.g
PPP, HDLC, Frame Relay), etc.

What I noticed was that each synchronous board in Linux provides a
different way of doing this, and it would be good for users to have a
single, standard interface (such as ifconfig) to do this type of
configuration. Maybe even patch ifconfig itself, I don't know ...

Questions:
- Is there any existing _standard_ interface to do that??
- If not, is there any existing _standard_ infrastructure (e.g. ioctls and
  structures) so that I can write an application to do that over this 
  standard structure?
- If not, where would be the right place in the kernel to change in order 
  to implement such infrastructure?

I'm interested in implementing this, but I don't want to reinvent the
wheel (if such wheel exists ...).

Thanks in advance for your comments.

Later,
Ivan
