Saurabh:
Sorry for not responding to this earlier.
Currently the "ifSpeed" refers to the interface speed provided by
the MIB's ifTable in RFC 2863.
Design of the DiffServ PIB is to be Role Combination specific and not
interface specific.  We also didn't want to pull in the MIB's ifTable into
a PIB as there are many proprietary extensions to the ifTable already.
Another point is that we can add this as part of the capabilities for
a specific Role Combination, but we may want to have a single Role
Combination containing interfaces of more than one interface speed.

I would like to leave it the way it is and just use the ifSpeed from the 
MIB's ifTable.
Let the DiffServ PIB get to Proposed Standard RFC.
Get more implementation experience to determine what is the right thing to do
before modifying it, as there are other things we will learn from more
implementation experience.
