Pedro F. Giffuni 718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags. 
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

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