I have disabled the ebpf mode by set bpfEnabled=false from https://docs.tigera.io/calico-cloud/operations/ebpf/enabling-ebpf#reversing-the-process, but there still a lot ebpf programs on nodes after set bpfEnabled=false.


latest felixconfig:
spec:
bpfEnabled: false
bpfLogLevel: ""
logSeverityScreen: Info
prometheusMetricsEnabled: true
reportingInterval: 0s


bpftool -j -p cgroup show /run/calico/cgroup

[{
"id": 73636,
"attach_type": "connect4",
"attach_flags": "",
"name": "calico_connect_"
},{
"id": 73641,
"attach_type": "connect6",
"attach_flags": "",
"name": "calico_connect_"
},{
"id": 73646,
"attach_type": "sendmsg4",
"attach_flags": "",
"name": "calico_sendmsg_"
},{
"id": 73654,
"attach_type": "sendmsg6",
"attach_flags": "",
"name": "calico_sendmsg_"
},{
"id": 73651,
"attach_type": "recvmsg4",
"attach_flags": "",
"name": "calico_recvmsg_"
},{
"id": 73659,
"attach_type": "recvmsg6",
"attach_flags": "",
"name": "calico_recvmsg_"
}
]

there still a lot ebpf programs on nodes after set bpfEnabled=false
also new joined nodes has these programs.
