Bug in BM imanager plugin

While working on filters for DHCP traffic I came across a
bug in imanager. Apparently imanager does not appreciate
the multicast address of 255.255.255.255. It complains it
is invalid. I was able to get the filter setup using
filtcfg. I then checked the new filter in imanager and it
did show the correct multicast address.

development team.
