What I did:
Added change not to create ECMP Group in SAI and program the route if none of the ECMP members are active/link-up.
Why I did:
In scale setup of T2 it's possible all links can go down simultaneously which case we can get Route messages with all nexthops being in down state. In such case we might create empty Nexthop Group in SAI for the given route which causes not needed SAI call for Nexthop Group creation and also create traffic blackhole for the route where that route can still forward traffic via default route if eligible/applicable.
How I verify:
