Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

* 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)
|
|
* ccr base 0x3f8
|
|
* cra (io 0xa)
|
|
* 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
|
|
*
|
|
* EN5017A, EN5020 no data, but very popular
|
|
* Other chips?
|
|
* NetBSD supports RTL8019, but none have surfaced that I can see

* PROM RAM
|

* Offset Offset What
|
|

|
|
* 14 28 0x57
|
|
* 15 30 0x57
|
|
*
|
|
* Some manufacturers have another image of enetaddr from
|
|
* PROM offset 0x10 to 0x15 with 0x42 in 0x1e and 0x1f, but
|
|
* this doesn't appear to be universally documented in the

|
* datasheets. Some manufactuers have a card type, card config
|
|
* checksums, etc encoded into PROM offset 6-13, but deciphering it
