Linux-2.6.12-rc2v2.6.12-rc2

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
