Has the patches pushed into FRR master as PRs?

@pavel-shirshov Here are the details :

0009-Link-local-scope-was-not-set-while-binding-socket-for-bgp-ipv6-link-local-neighbors.patch => PR FRRouting/frr#7434

0010-VRF-interface-lookup-was-still-done-in-the-default-vrf.patch => This fix is not needed in master branch as all interface up/down/add/delete events are replaced with ifp callbacks using PR FRRouting/frr#5009, and it is merged.

0011-Changes-to-send-ipv6-link-local-address-as-nexthop-to-fpmsyncd.patch => This fix is not needed in master as already relevant below PRs are raised and merged.
BGP : Fix for nexthop as IPv4 mapped IPv6 address : FRRouting/frr#6821
