- 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.
