Description:
After updating libpcap, libvirt segfaults (see bug report 28735). The problem is that libvirt ends up getting linked against 2 different versions of libnl:
1) libnl-3 because of libpcap
2) libnl-1 because of netcf.

In the configuration process (./configure) netcf searches for libnl-1, so linking it against libnl3 without patching it is not an option.
The question is: Do we gain anything from patching libpcap to link against a newer libnl version? If not, since it is causing problems, shouldn't it roll back to previous state?
I recompiled libpcap without the libnl32.patch and libvirt does not segfault any more.

Additional info:
* Affected version: libpcap-1.2.1-2
This task depends upon

netcf-0.1.9-2 links against libnl-3.

Unfortunately libvirt itself also links against libnl-1. The attached file contains a patch, PKGBUILD, etc. to fix this.

Now libvirt works for me again without crashing!
