9b1db80125 Use the new bus device_shutdown hook for performing the shutdown action
on the ee16 parts rather than explicitly registering an event handler
that wasn't being torn down on detach.

9ceedf231b Rename the ie_EE16 module to just 'ie' so that at least one of the modules
for this driver is called 'ie'.  Otherwise, ifconfig(8) doesn't recognize
any of the modules as being the ie(4) driver and will always try to kldload
the driver even when it is already present in the kernel.

d98e0a2859 - Fix two calls to ieinit() in ieioctl() to call ieinit_locked() instead to
avoid recursing on the lock.

00f1da89ab Make ie(4) MPSAFE:
- Add a mutex to the softc and use it to protect the softc and device.
- Setup the interrupt handler in the common code instead of in each front
  end and do it after ether_ifattach().
- Use ie_stop() and ieinit_locked() in iereset() rather than frobbing IFF_UP
  and invoking ieioctl().
- Use DELAY() to implement a spin loop on a register with a timeout rather
  than scheduling a timeout and then doing a tight spin on the register.
  In the non-MPSAFE case this would never have worked because the spinning
  code held Giant and the timeout routine would have been blocked on Giant
  forever.  The same approach would not worke in the MPSAFE case either for
  the same reason, hence use a loop around DELAY().
- Clear IFF_DRV_(RUNNING|OACTIVE) in ie_stop() rather than in callers.
- Call ieinit_locked() directly rather than ieioctl(!) from ie_mc_reset().
- Don't leak the rx frame buffer on detach.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
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.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

bb11094995 Don't use pessimal (u_short) types for i/o ports. This is mainly for
completenss.  The pessimization is tiny compared with i/o port slowness
except on very old machines, but code that used signed short types for
i/o ports was unpessimized long ago, and the macro that detected it
recently started working for u_short types too.  Use of bus space
should have made this moot long ago.

d0859c8567 Clear the IFF_OACTIVE flag at the end of ieinit(). This prevents

of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

Collect together the components of several drivers and export eisa from

been updated to work on the Alpha yet, but that can come later.

Repository copies were done a while ago.
Moving these now keeps them in consistant place across the 4.x series
