* Git repository: <http://rcs-git.duckcorp.org/hurdfr/bpf.git/>
The patch for [[GNU Mach|microkernel/mach/gnumach]] is expected to be
complete and functional, the [[hurd/translator]] less so -- amongst others,
there are unresolved issues concerning support of [[hurd/glibc/IOCTL]]s.

* [[!GNU_Savannah_patch 6619]] -- pfinet uses the virtual interface
* [[!GNU_Savannah_patch 6620]] -- pfinet changes its filter rules with
its IP address

promiscuous mode
