+Do not invasively check for BPF (Ethernet check queries presence
+of /dev/bpfX): we know that FreeBSD has BPF and ports can be *built*
+inside infrastructure that has no such /dev entries; like a jail
+without devfs configured to unhide BPF devices.
+
+The presence of the net/bpf.h is checked in configure earlier,
+so sanity checks for the build environment will still be present.
+
+Macro HAVE_BSD_BPF won't be defined after this modification,
+but as of libdnet-1.13 it is not used at all inside libdnet's code.
