/jira backport

bfdd opens 5 (2 IPv4 + 3 IPv6) UDP sockets against each VRF even if BFD
has not been explicitly enabled on them. When using RouteAdvertisements
with OVN-K CUDNs, this limits the scalability to ~200 of them assuming a
default file descriptor limit of 1024. Bump it to 65536 which is in any
case a much more reasonable limit for production network daemons.
