Warner Losh 188ddb1837 When the miibus for the AX88x90 or TC5299J cards fails to attach, we
would call ed_release_resources() when we should have called
ed_detach() to properly undo the effects of prior calls to
ed_attach().  This would leave a stray ed interface ifnet alive in the
system, which was, well, bad, since we called if_free() on the
underlying memory...  Fix the ed_detach routine to cope being called
in this context now.

This should never come up because the miibus is always there.  Except
for now when it seems to be failing for reasons unknown...  That's a
different bug that hits at least ed, xl, dc and fxp...

* Notes for adding media support. Each chipset is somewhat different

* 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
* TMI tc5299 10/100 chip, has a different MII interaction than
* dl100xx and ax88x90.
*
* EN5017A, EN5020 no data, but very popular
* Other chips?
* NetBSD supports RTL8019, but none have surfaced that I can see
