Why I did it
dplane_fpm_nl is a new FPM implementation in FRR. The old plugin fpm will not have any new features implemented. Usage of the new plugin gives us ability to use BGP suppression feature and next hop groups in the future.
How I did it
Switch to dplane_fpm_nl zebra plugin from old fpm plugin which is not supported anymore
Remove stale patches for old fpm plugin and add similar patches for dplane_fpm_nl
How to verify it
Build and run on the switch.
