+pppd: Implement support for precompiled pcap filters
+
+This patch implements support for precompiled pcap filters which is useful to
+support dial-on-demand on memory constrained embedded devices without having
+to link the full libpcap into pppd to generate the filters during runtime.
+
+Two new options are introduced; "precompiled-pass-filter" specifies a pre-
+compiled filter file containing rules to match packets which should be passed,
+"precompiled-active-filter" specifies a filter file containing rules to match
+packets which are treated as active.
