ISA/PCI chipset (RTL8019 and RTL8029).  Eliminate ED_NO_MIIBUS option.
You are now required to have miibus if you have pccard in your kernel
(but not required if you don't!).  Split out register definitions for
possible future subsetting.

o New APIs to access CIS, attribute memory and pccard registers
o Lock ed driver
o Support more cards in ed, ep, sn, xe
o Use new APIs to get MAC address right more often.

  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;

Hopefully this fixes ed(4) under qemu.  I'm shocked that real hardware
is apparently working with these bugs.

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.

use them in the macros.  Since the rman_get_bus{tag,handle} transitioned
from macros to function calls, this unpessimizes that conversion.

certain options aren't enabled.
