34 * Notes for adding media support.  Each chipset is somewhat different
35 * from the others.  Linux has a table of OIDs that it uses to see what
36 * supports the misc register of the NS83903.  But a sampling of datasheets
37 * I could dig up on cards I own paints a different picture.
38 *
39 * Chipset specific details:
40 * NS 83903/902A paired
41 *    ccr base 0x1020
42 *    id register at 0x1000: 7-3 = 0, 2-0 = 1.
43 *	(maybe this test is too week)
44 *    misc register at 0x018:
45 *	6 WAIT_TOUTENABLE enable watchdog timeout
46 *	3 AUI/TPI 1 AUX, 0 TPI
47 *	2 loopback
48 *      1 gdlink (tpi mode only) 1 tp good, 0 tp bad
49 *	0 0-no mam, 1 mam connected
50 * NS83926 appears to be a NS pcmcia glue chip used on the IBM Ethernet II
51 * and the NEC PC9801N-J12 ccr base 0x2000!
52 *
53 * winbond 289c926
54 *    ccr base 0xfd0
55 *    cfb (am 0xff2):
56 *	0-1 PHY01	00 TPI, 01 10B2, 10 10B5, 11 TPI (reduced squ)
57 *	2 LNKEN		0 - enable link and auto switch, 1 disable
58 *	3 LNKSTS	TPI + LNKEN=0 + link good == 1, else 0
59 *    sr (am 0xff4)
60 *	88 00 88 00 88 00, etc
61 *
62 * TMI tc3299a (cr PHY01 == 0)
63 *    ccr base 0x3f8
64 *    cra (io 0xa)
65 *    crb (io 0xb)
66 *	0-1 PHY01	00 auto, 01 res, 10 10B5, 11 TPI
67 *	2 GDLINK	1 disable checking of link
68 *	6 LINK		0 bad link, 1 good link
69 * TMI tc5299 (not seen in the wild, afaik) 10/100 chip
70 *
71 * EN5017A, EN5020	no data, but very popular
72 * Other chips?
73 * NetBSD supports RTL8019, but none have surfaced that I can see

109 * PC Cards should be using a network specific FUNCE in the CIS to
110 * communicate their MAC address to the driver.  However, there are a
111 * large number of NE-2000ish PC Cards that don't do this.  Nearly all
112 * of them store the MAC address at a fixed offset into attribute
113 * memory, without any reference at all appearing in the CIS.  And
114 * nearly all of those store it at the same location.
115 *
116 * This applies only to the older, NE-2000 compatbile cards.  The newer
117 * cards based on the AX88x90 or DL100XX chipsets have a specific place
118 * to look for MAC information.  And only to those NE-2000 compatible cards
