All patches should have a description + Signed-off-by. Also, you should
use the proper naming convention for patches:
<package>-<sequencenumber>-<description>.patch
I know there's already a patch for dhcpdump that doesn't follow this
convention, but you're invited to rename it as well :-)

Is _BSD_SOURCE really meant to be tested within source code? I thought
it was more the application or library that would #define _BSD_SOURCE
or #define _GNU_SOURCE to tell the C library which functions should be
made visible. But well, if strsep() depends on _BSD_SOURCE being
defined, I agree that testing _BSD_SOURCE is a way of knowing whether
it's available or not.
Are there some other opinions about this?
