[snmp] SNMP v3 discovery bug in 5.1

[Josh Bers]

Birgit,

I have confirmed the success of the fix. One strange behavior: On failure
when disconnected, it takes about 10 seconds for the discovery timeout to
happen even though my retry array is [750, 1500, 2250]. Does discovery try
twice per retry?

We would like to get a new release of the stack with this fix in place as
it makes SNMPv3 usable for our application. Can you give me an estimate
for when the next release will be available?

Regards,

 Josh
