and update comments about original patches doing this and it not working. It works for both the DL10019 and DL10022 based cards that I have. It really helps the DL10019 cards, since they were using 8k instead of the normal 16k that regular NE-2000 cards help. # Note to self: need to provide a common routine to setup memory # parameters.

* Notes for adding media support. Each chipset is somewhat different

|
|
* I could dig up on cards I own paints a different picture.

|

* Chipset specific details:
|
|
* NS 83903/902A paired
|
|
* ccr base 0x1020
|
|
* id register at 0x1000: 7-3 = 0, 2-0 = 1.
|
|
* (maybe this test is too week)
|
|
* misc register at 0x018:
|
|
* 6 WAIT_TOUTENABLE enable watchdog timeout
|
|
* 3 AUI/TPI 1 AUX, 0 TPI
|
|
* 2 loopback
|
|
* 1 gdlink (tpi mode only) 1 tp good, 0 tp bad
|
|
* 0 0-no mam, 1 mam connected
|
|
*
|
|
* NS83926 appears to be a NS pcmcia glue chip used on the IBM Ethernet II
|
|
* and the NEC PC9801N-J12 ccr base 0x2000!
|
|
*
|
|
* winbond 289c926
|
|
* ccr base 0xfd0
|
|
* cfb (am 0xff2):
|
|
* 0-1 PHY01 00 TPI, 01 10B2, 10 10B5, 11 TPI (reduced squ)
|
|
* 2 LNKEN 0 - enable link and auto switch, 1 disable
|
|
* 3 LNKSTS TPI + LNKEN=0 + link good == 1, else 0
|
|
* sr (am 0xff4)
