Linus Torvalds 1da177e4c3 Linux-2.6.12-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

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.
