net-pf-17 must be aliased to af_packet in order for PF_PACKET sockets to work correctly i.e., for the kernel to autoload the module. Since this is a fixed alias, like net-pf-4 being ipx, this should be added to the modprobe default configuration.

This appears to have been fixed for a while. Marking as resolved in the current release.
