Documentation: remove obsolete networking/multicast.txt file 



The original intent of this file was to list limitations in
drivers/hardware relating to multicast use, back when some
modest hardware from the early 1990s did not support things
we might take for granted today.

I was intending to delete some now-gone MCA/token ring entries
in this file, but once I opened it, I found it only contained
information on the earliest (pre-2000) linux networking drivers.

Checking the git history shows that the file hasn't been touched
since 2005.  Clearly nobody is actively consulting this file
as a meaningful reference.

Rather than add a "YES YES YES" line for all of the drivers we
currently have, lets just take advantage of the fact that nobody
is using the file to delete it.

This has the side benefit of not having to do a line-by-line
deletion of the file content as each older driver is expired.

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

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.
