33 * from the others. Linux has a table of OIDs that it uses to see what
34 * supports the misc register of the NS83903. But a sampling of datasheets
35 * I could dig up on cards I own paints a different picture.
37 * Chipset specific details:
38 * NS 83903/902A paired
40 * id register at 0x1000: 7-3 = 0, 2-0 = 1.
41 * (maybe this test is too week)
42 * misc register at 0x018:
43 * 6 WAIT_TOUTENABLE enable watchdog timeout
44 * 3 AUI/TPI 1 AUX, 0 TPI
46 * 1 gdlink (tpi mode only) 1 tp good, 0 tp bad
47 * 0 0-no mam, 1 mam connected
48 * NS83926 appears to be a NS pcmcia glue chip used on the IBM Ethernet II
49 * and the NEC PC9801N-J12 ccr base 0x2000!
54 * 0-1 PHY01 00 TPI, 01 10B2, 10 10B5, 11 TPI (reduced squ)
55 * 2 LNKEN 0 - enable link and auto switch, 1 disable
56 * 3 LNKSTS TPI + LNKEN=0 + link good == 1, else 0
58 * 88 00 88 00 88 00, etc
60 * TMI tc3299a (cr PHY01 == 0)
64 * 0-1 PHY01 00 auto, 01 res, 10 10B5, 11 TPI
65 * 2 GDLINK 1 disable checking of link
66 * 6 LINK 0 bad link, 1 good link
67 * TMI tc5299 10/100 chip, has a different MII interaction than
68 * dl100xx and ax88x90.

111 * NE-2000 based PC Cards have a number of ways to get the MAC address.
112 * Some cards encode this as a FUNCE. Others have this in the ROMs the
113 * same way that ISA cards do. Some have it encoded in the attribute
114 * memory somewhere that isn't in the CIS. Some new chipsets have it
115 * in special registers in the ASIC part of the chip.
117 * For those cards that have the MAC adress stored in attribute memory,
118 * nearly all of them have it at a fixed offset (0xff0). We use that
119 * offset as a source of last resource if other offsets have failed.
