Signed-off-by: Stepan Blyschak stepanb@nvidia.com DEPENDS: #12852 Why I did it To support BGP pending FIB suppression. How I did it I backported patches from FRR 8.4 feature that allows communicating ASIC route status back to FRR. Also, added a new field in DEVICE_METADATA YANG model table. Added UT for YANG model changes. How to verify it Run on the switch.
