===========================================
-3.1) ether=
------------
-
-:Syntax: ether=[<irq>[,<base_addr>[,<mem_start>[,<mem_end>]]]],<dev-name>
-
-<dev-name> is the name of a net driver, as specified in
-drivers/net/Space.c in the Linux source. Most prominent are eth0, ...
-eth3, sl0, ... sl3, ppp0, ..., ppp3, dummy, and lo.
-
-The non-ethernet drivers (sl, ppp, dummy, lo) obviously ignore the
-settings by this options. Also, the existing ethernet drivers for
-Linux/m68k (ariadne, a2065, hydra) don't use them because Zorro boards
-are really Plug-'n-Play, so the "ether=" option is useless altogether
-for Linux/m68k.

--------

-3.4) st=
+3.3) st=
--------
:Syntax: st=<buffer_size>,[<write_thres>,[<max_buffers>]]
