Log Message:
-----------
Add option on DEVMON tag line to specify custom IP address using ip()
Very handy for devices with multiple interfaces which choose a different
source IP address for their SNMP reply packets than the primary IP in
bb-hosts definitions.
e.g.
(from bb-hosts file)

10.0.0.11 multihomehost # conn=worst,10.0.0.12 DEVMON:ip(10.0.0.12)
