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.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
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.

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.

108663cc87 ccs is a size_t. RAY_CCS_INDEX takes ccs and does math on it,
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.

Aslo add 'z' to a nearby debug statement that's never compiled in.

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

60453b06de Primary purpose of this commit is to enable support for the Aviator
Pro and Raylink cards with version 5 firmware. Only infra-structure
mode has been tested. Specific changes for this feature are:

        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

a07736d0f6 Take advantage of the fixes to the pcic code that allows multiple
active memory maps. This removes the need to change the memory
map from common to attribute every time a packet is sent/received.

This increases performance and decreases cpu load (ping times on
slow machines improve by about 1.5ms).

Move out the old common memory/attrbiute memory hack functions to a
new header file to tidy up the main code. I want to keep them available
for a while.
