Adrian Bunk 5aa83a4c0a [PATCH] remove two obsolete net drivers
The options FMV18X and SK_G16 do depend on the non-available
  CONFIG_OBSOLETE even in kernel 2.4 - IOW, the last time it was able to
  select them was in kernel 2.2 (or even before).
  
  Since it seems noone misses these drivers, this patch removes them.

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.
