attribute memory at 0xff0 to find its MAC address. This is another instance of the IBM ethercard II from all apperances (short of popping the lid). Update the entry to document which cards we support actually need this functionality.

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

|
* from the others. Linux has a table of OIDs that it uses to see what
|
|
* supports the misc register of the NS83903. But a sampling of datasheets
|
|
* 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)
|
|
* 88 00 88 00 88 00, etc
|
|
*
|

* TMI tc3299a (cr PHY01 == 0)
|

|
* crb (io 0xb)
|
|
* 0-1 PHY01 00 auto, 01 res, 10 10B5, 11 TPI
|
|
* 2 GDLINK 1 disable checking of link
|
|
* 6 LINK 0 bad link, 1 good link
|
|
* TMI tc5299 (not seen in the wild, afaik) 10/100 chip
|
|
*
|
|
* EN5017A, EN5020 no data, but very popular
|
|
* Other chips?
|
|
* NetBSD supports RTL8019, but none have surfaced that I can see
