Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+Behaviour of Cards Under Multicast
+==================================
+
+This is how they currently behave, not what the hardware can do--for example,
+the Lance driver doesn't use its filter, even though the code for loading
+it is in the DEC Lance-based driver.
+
+The following are requirements for multicasting
+-----------------------------------------------
+AppleTalk Multicast hardware filtering not important but
+ avoid cards only doing promisc
+IP-Multicast Multicast hardware filters really help
+IP-MRoute AllMulti hardware filters are of no help
+
+
+Board Multicast AllMulti Promisc Filter

+PROMISC = This multicast mode is in fact promiscuous mode. Avoid using
+cards who go PROMISC on any multicast in a multicast kernel.
+
+(#) = Hardware multicast support is not used yet.
+(*) = Hardware support for Davicom 9132 chipset only.
