The kernel module *should* work. I suspect that there is an error
message when it tries to load the module and fails. You could check
for that error message, or try to load the module by hand and see if
you get a clue to the problem.
Here is how I did: commented out the "device bpf" line in the kernel,
built and installed the kernel, and added ng_bpf_load="YES" in
loader.conf. I guess this is the module for the bpf (is this correct?
I'm not 100% sure). So, booting with the new kernel, and the module
being loaded from the loader.conf, the pflogd fails to start with this
error:
Nov 11 20:22:33 uxterm pflogd[10251]: Failed to initialize: (no
devices found) /dev/bpf0: No such file or directory
Nov 11 20:22:33 uxterm pflogd[10251]: Exiting, init failure
And, tcpdump also fails saying that "no suitable device found". Of
course there is no /dev/bpf0.
Unfortunately, I do not have enough experience to figure out how to
load this device at runtime. Is there any solution to this situation?
