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 * NS83926 appears to be a NS pcmcia glue chip used on the IBM Ethernet II
49 * and the NEC PC9801N-J12 ccr base 0x2000!
50 *
51 * winbond 289c926
52 *    ccr base 0xfd0
53 *    cfb (am 0xff2):
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
57 *    sr (am 0xff4)
58 *	88 00 88 00 88 00, etc
59 *
60 * TMI tc3299a (cr PHY01 == 0)
61 *    ccr base 0x3f8
62 *    cra (io 0xa)
63 *    crb (io 0xb)
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.
69 *
70 * EN5017A, EN5020	no data, but very popular
71 * Other chips?
72 * NetBSD supports RTL8019, but none have surfaced that I can see
