Marius Strobl f6030d6ac1 - Switch to using the common MII bitbang'ing code instead of duplicating it. 
- Based on lessons learnt with dc(4) (see r185750), add bus space barriers to
  the MII bitbang read and write functions as well as to instances of page
  switching.
- Add missing locking to ed_ifmedia_{upd,sts}().
- Canonicalize some messages.
- Based on actual functionality, ED_TC5299J_MII_DIROUT should be rather named
  ED_TC5299J_MII_DIRIN.
- Remove unused headers.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.

* 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
