Linux network driver modules
|
|
|
|
Do not mistake this for "README.modules" at the top-level
|
|
directory! That document tells about modules in general, while
|
|
this one tells only about network device driver modules.
|
|
|
|
This is a potpourri of INSMOD-time(*) configuration options
|
|
(if such exists) and their default values of various modules
|
|
in the Linux network drivers collection.
|
|
|
|
Some modules have also hidden (= non-documented) tunable values.
|
|
The choice of not documenting them is based on general belief, that
|
|
the less the user needs to know, the better. (There are things that
|
|
driver developers can use, others should not confuse themselves.)
|
|
|
|
In many cases it is highly preferred that insmod:ing is done
|
|
ONLY with defining an explicit address for the card, AND BY
|
|
NOT USING AUTO-PROBING!
|
|
|
|
Now most cards have some explicitly defined base address that they
|
|
are compiled with (to avoid auto-probing, among other things).
|
|
If that compiled value does not match your actual configuration,
|
|
do use the "io=0xXXX" -parameter for the insmod, and give there
|
|
a value matching your environment.
|
|
|
|
If you are adventurous, you can ask the driver to autoprobe
|
|
by using the "io=0" parameter, however it is a potentially dangerous
|
|
thing to do in a live system. (If you don't know where the
|
|
card is located, you can try autoprobing, and after possible
|
|
crash recovery, insmod with proper IO-address..)
|
|
|
|
--------------------------
|
|
(*) "INSMOD-time" means when you load module with
|
|
/sbin/insmod you can feed it optional parameters.
|
|
See "man insmod".

8390 based Network Modules (Paul Gortmaker, Nov 12, 1995)
|
|
--------------------------
|
|
|
|
(Includes: smc-ultra, ne, wd, 3c503, hp, hp-plus, e2100 and ac3200)
|
|
|
|
The 8390 series of network drivers now support multiple card systems without
|
|
reloading the same module multiple times (memory efficient!) This is done by
|
|
specifying multiple comma separated values, such as:
|
|
|
|
insmod 3c503.o io=0x280,0x300,0x330,0x350 xcvr=0,1,0,1
|
|
|
|
The above would have the one module controlling four 3c503 cards, with card 2
|
|
and 4 using external transceivers. The "insmod" manual describes the usage
|
|
of comma separated value lists.
|
|
|
|
It is *STRONGLY RECOMMENDED* that you supply "io=" instead of autoprobing.
|
|
If an "io=" argument is not supplied, then the ISA drivers will complain
|
|
about autoprobing being not recommended, and begrudgingly autoprobe for
|
|
a *SINGLE CARD ONLY* -- if you want to use multiple cards you *have* to
|
|
supply an "io=0xNNN,0xQQQ,..." argument.
|
|
|
|
The ne module is an exception to the above. A NE2000 is essentially an
|
|
8390 chip, some bus glue and some RAM. Because of this, the ne probe is
|
|
more invasive than the rest, and so at boot we make sure the ne probe is
|
|
done last of all the 8390 cards (so that it won't trip over other 8390 based
|
|
cards) With modules we can't ensure that all other non-ne 8390 cards have
|
|
already been found. Because of this, the ne module REQUIRES an "io=0xNNN"
|
|
argument passed in via insmod. It will refuse to autoprobe.
|
|
|
|
It is also worth noting that auto-IRQ probably isn't as reliable during
|
|
the flurry of interrupt activity on a running machine. Cards such as the
|
|
ne2000 that can't get the IRQ setting from an EEPROM or configuration
|
|
register are probably best supplied with an "irq=M" argument as well.
