[f-nsp] Better traffic distribution on LAG

[Frank Bulk]

I'm running into an issue where our transport gear can't have their LAGs
hash on IP for egress (from Transport #2 to Brocade MLXe #2), so I need a
way generate more IPs (and MAC addresses) so I can use ECMP on Brocade MLXe
#1 to send traffic to both IPs (and therefore both MACs), and then traffic
should be load-balanced across those unique MACs. 

Here's the existing network design:

Internet
    |
Brocade MLXe #1
    |
   10G
  tagged
 VLAN 500
    |
 UNI port
Transport #1
   NNI 
  /   \
 /     \
 |      |
 |      |
 \     /
  \   /
   NNI
Transport #2
  |  |  |  |
 1G 1G 1G 1G
     LAG
    tagged
   VLAN 500
  |  |  |  |
 Brocade MLXe #2
     |

What about VRRP on the Brocade MLXe #2, and then have a route on the Brocade
MLXe #1 to both the Master IP and Local IP that reside on Brocade MLXe #2?
There wouldn't be a Backup for the VRRP, but that doesn't matter, just need
unique MAC addresses for each Master and Local IP.  That would at least use
two of the four GigE's.
