Re: (there are no BPF devices)

Hi again,
here we go.....

# sysctl kern.drivers
.... [32 -1 bpf] ....

# modstat bpf
NAME             CLASS      SOURCE     REFS  ADDRESS          SIZE
REQUIRES 
bpf              driver     builtin    8     0                -        -

# fstat | grep bpf
(gives nothing)

# ktrace tcpdump arp
tcpdump: no suitable device found

(kdump skipped)
