RE: FlowId and FlowIdOrAny



Ok, good, cause I was surprised to see a -1 in an Unsigned32.

Now... if we do this, then this could still be used by the
framework pib. 
However, for the diffserv-mib it would mean they must 
deprecate a current object and create a new one (switching
from Unsigned to Integer32 causes a change on the wire!).

The solution presented earlier could be considered as a
bug fix and would not require the diffserv-MIB to
deprecate the existing object

Thanks,
Bert
