[SR-Users] LCR module : same IP address for different prefix.

[Antanas Masevicius]

Hello Ricardo,

I already wrote on this list about this issue. Currently the only way to
do it is to disable duplicate gws checking in sources itself.
In general, gw duplication checking should be extended to check not only
by ip_addr or its hostname, but to include 'tag' and even 'strip' columns.
IMHO duplication checking could be removed at all and only DB unique
constraint checking used.
