32 * Notes for adding media support.  Each chipset is somewhat different
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.
36 *
37 * Chipset specific details:
38 * NS 83903/902A paired
39 *    ccr base 0x1020
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
45 *	2 loopback
46 *      1 gdlink (tpi mode only) 1 tp good, 0 tp bad
47 *	0 0-no mam, 1 mam connected
48 *
49 * NS83926 appears to be a NS pcmcia glue chip used on the IBM Ethernet II
50 * and the NEC PC9801N-J12 ccr base 0x2000!
51 *
52 * winbond 289c926
53 *    ccr base 0xfd0
54 *    cfb (am 0xff2):
55 *	0-1 PHY01	00 TPI, 01 10B2, 10 10B5, 11 TPI (reduced squ)
56 *	2 LNKEN		0 - enable link and auto switch, 1 disable
57 *	3 LNKSTS	TPI + LNKEN=0 + link good == 1, else 0
58 *    sr (am 0xff4)
59 *	88 00 88 00 88 00, etc
60 *
61 * TMI tc3299a (cr PHY01 == 0)
62 *    ccr base 0x3f8
63 *    cra (io 0xa)
64 *    crb (io 0xb)
65 *	0-1 PHY01	00 auto, 01 res, 10 10B5, 11 TPI
66 *	2 GDLINK	1 disable checking of link
67 *	6 LINK		0 bad link, 1 good link
68 *
69 * EN5017A, EN5020	no data, but very popular
70 * Other chips?
71 * NetBSD supports RTL8019, but none have surfaced that I can see

107 * NE-2000 based PC Cards have a number of ways to get the MAC address.
108 * Some cards encode this as a FUNCE.  Others have this in the ROMs the
109 * same way that ISA cards do.  Some have it encoded in the attribute
110 * memory somewhere that isn't in the CIS.  Some new chipsets have it
111 * in special registers in the ASIC part of the chip.
112 *
113 * For those cards that have the MAC adress stored in attribute memory
114 * outside of a FUNCE entry in the CIS, nearly all of them have it at
115 * a fixed offset (0xff0).  We use that offset as a source of last
116 * resource if other offsets have failed.  This is the address of the
117 * National Semiconductor DP83903A, which is the only chip's datasheet
118 * I've found.
