Description
In 1.2.x, users frequently add an interface to load balancer pools multiple times to unequally load balance traffic. 2.0 has no equivalent, which is a major regression in functionality for many users.

This seems to work correctly for static gateways, and copies of dynamic gateways, but does not work for actual dynamic gateway entries.
The field doesn't save its value properly.

This is working great for me now.
I set a weight of 1 on my DSL (PPPoE, 3Mbit), and 3 on cable (DHCP, 10Mbit), and I am seeing a 3:1 ratio of connection balancing, even with dynamic gateways.
More testing by others with different WAN gateway setups may be helpful, but in my case it's good.

And I'm not sure if we'd want to keep this ticket open or start a new one for the upgrade code to migrate from the old style to this, it could get a bit involved.

A quick before-and-after from one scenario, load balanced WAN and OPT1 where WAN was weighted 3 in the old style.
Before:
<load_balancer>
<lbpool>
<type>gateway</type>
<behaviour>balance</behaviour>
<monitorip/>
<name>LoadBalance</name>
<desc>Balance Load between WAN and OPT1</desc>
<port/>
<servers>wan|x.x.x.x</servers>
<servers>wan|x.x.x.x</servers>
<servers>wan|x.x.x.x</servers>
<servers>opt1|y.y.y.y</servers>
<monitor/>
</lbpool>
</load_balancer>
After
<gateways>
<gateway_group>
<name>LoadBalance</name>

Better not go down the upgrade route for the weight. A lot of users have multiple loadbalancer pools, which means we have no idea which interface count from which pool we should use for the weight.
This means we can not reliably and predictably upgrade the configuration. Even without the weight we get reliable connectivity and at that point it's easy to change the weight of a gateway.

Fair enough, since the original method wasn't really "official" anyhow. We may just want to make a note of this in the upgrade notes for 2.0 when the time comes.
