OK, so it sounds like this idea of replacing lwIP's SNMP with a
roll-your-own version is something that we should do our best to
support.

I meant "is MIB-2 required for the agent currently in lwIP", not "is
MIB-2 required for all any SNMP agent".

In general, if the SNMP agent already in lwIP is considered too
heavyweight, is there any interest in cutting it down, either by adding
a complete replacement along the lines of your version, or by making
more of the features in the lwIP agent compile-time configurable?  I've
no idea how feasible either of those are, but wondered if it warrants a
task opening in savannah.
