dhclient dependency on bpf ?

[Saifi Khan]

Hi:

In a custom kernel configuration, i disabled 'bpf'.

On, running the following command:
amd64x2# dhclient nfe0

the following output is seen,

got link
Oct 22 20:24:14 amd64x2 dhclient[850]: 
Can't find free bpf: No such file or directory
Can't find free bpf: No such file or directory
Oct 22 20:24:14 amd64x2 dhclient[850]: exiting.

#uname -a
DragonFly amd64x2 2.4.1-RELEASE DragonFly v2.4.1.13.g295d3-RELEASE

Offcourse, i enabled 'bpf' and i'm keen to know what is the
reason for 'bpf' dependency ?


thanks
Saifi.
