struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.
The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either. It was later assuming that IF_DEQUEUE would
give him this same mbuf.

possible to have different probe/attach semantics between the two
systems and yet still use the same driver for both.
Compatibility methods for OLDCARD drivers. We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects. For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines. For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.
compat devices should use the following:
/* Device interface */
DEVMETHOD(device_probe), pccard_compat_probe),

This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.

you had to have multiple ISA boards in non-PnP mode with an 'unknown' board
with a lower MAC address to find this one. Since I have 4 3c5x9 boards
in my test box I was somewhat confused when this happened. :)
Make the messages printed by ep_isa_identify() a little more consistent;
we'll only see them in verbose boot mode but it makes me feel better if
they look nice.
Also, while I'm here, add a mechanism to catch unknown board IDs that

We now correctly skip boards that have PnP support enabled, or are in

probing, as per the databook.
- ISA only

We will allow cards that can be dealt with by PnP to be attached by the
PnP enumerator.
This fixes the bogus detection of boards at weird ioports.
problem.
o Create new timeout routine so we don't detach the card inside a ISR
but instead drop back to spl0 via a timeout of 0.
o Actually delete the child of the pccard device rather than just faking
it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather
than void.
o Fix ep and ed pccard detach routines to use if_detach rather than just
if_down. if_detach destroys the device, while if_down just marks it
down. In this incarnation of the pccard things, we map the disable
the slot action to detach the driver, which removes the driver from the
device tree. When that is done, a panic would soon follow as the
ifconfig tried to down the device.
Didn't fix:
o Should cache the pccard dev child's pointer in struct slot
o remove now unused parts of struct slot
o Any driver using softc after detach has been called. sio's softc used
to be statically allocated, so you could check sc->gone, but that is
now gone.
o Didn't remove gone from softc of drivers that use the old pccard method.
Didn't test:
o ed driver changes
o sio driver changes on pccards
o suspend (no laptop or apm support on my desktop)
test this support since I don't have the dongle for the card in

in transit from freebsdcon, or a mis-matched dongle...
pccard attachments must activate the resources they want to access.
ep didn't do this, so of course thee eeprom came back as busy. ed and
sio already did this. It was only due to a bug in the logic that the
probe succeeded. These problems have been fixed.
- Rip out all the static softc stuff and do softc allocation the right way.
- Rewrite most of the ISA code so that it provides a DEVICE_IDENTIFY
method to enumerate all non-PnP ISA devices.
This has the following consequences:
- No 'ep' devices may be hardwired.
- All hardwired devices will probably be detected twice.
By hardwired I mean:
device ep0 at isa? port 0x300 irq 10
- 'ep' devices are ordered by bus, slot, and then MAC address.
- Make 3c509B cards work in PnP mode. Yes, they really work.
- Convert over to using ifmedia for media selection. No more of this
lame 'linkX' stuff.
- Consolidate a lot of duplicated code.
- Make a stab at not breaking MII based PCCARD devices.
I doubt that the PCCARD stuff works any more than it did before my
changes but theres hope. My PCCARD hardware should arrive in a
week or so.
- Retreive the media settings from the card EEPROM rather than guessing.
I've got a 3c509-TPO that thinks its got an AUI port and if others
can report similar problems I'll write a bit of clever code that will
fix this but right now it works correctly on all but 1 card.
- Clean up a few things and make some cosmetic changes.
- Add myself as the MAINTAINER since nobody else wants to. I'm
in the best position to do this as I've got an example of most
of the cards:
EISA 3c579 bnc/aui
MCA 3c529 tp/aui
ISA 3c509 tpo
ISA-PnP 3c509B combo
If someone wants to send me a any cards I don't have I'd appriciate
it. Also welcome are 3c59x boards since I'll be folding if_vx and
if_ep at some point.
I'm committing this from a laptop running this driver. Have only one
devclass for all ep devices (at least for pccard and eisa) so unit
numbering is sane. Might not work with both isa and non-isa devices

pipeline which should resolve this, he wanted me to commit this so he
