bgpd-scale-update-delay-packing.patch

ISSUE:
During startup, BGP update prefix packing wasnt optimal and route installation
was found to be spread over.

SOLUTION:
With this patch, update-delay post processing is serialized to achieve:
 a. better peer update packing
    (which helps in reducing total number of BGP update packets)
 b. installation of the resulting routes in zebra as close to each others
    as possible.
    (which can help zebra batch its processing and updates to Kernel better)
