one) ifaddr_byindex() users were converted to use ifp->if_addr.

handler depended on the ifp being still alive, this could, in theory,
cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.
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.

MFC after: 1 week
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.

resulting in a size_t due to C's rules of arithmetic. Rather than
bogusly cast the result to a uint8_t, fix the printf format specifier
to have a 'z' modifier which tells the compiler that the sizes really
do match.
It turns out that change 1.75 was incorrect to assume that this
'really' was a 8bit quantity. It isn't. Although the hardware
appears to limit things to < 256, it would be a bug that should be
caught by debug printf it it were. Casting it to uint8_t would have
lost this useful information.

This change paves the way for interface renaming and enhanced pseudo

Pro and Raylink cards with version 5 firmware. Only infra-structure

o Add RFC1042 encapsulation of IP datagrams
o Add authentication and association
o Decode of the beacon (although not used)
Other changes have been made:
o Pass command completion status to *_done (in place for
adding proper error recovery)
o Move a couple of state variables into the current
network parameters structure. This is in prep. for
