b5c9941514 Clarify/fix handling of the current channel:
o add ic_curchan and use it uniformly for specifying the current
  channel instead of overloading ic->ic_bss->ni_chan (or in some
  drivers ic_ibss_chan)
o add ieee80211_scanparams structure to encapsulate scanning-related
  state captured for rx frames
o move rx beacon+probe response frame handling into separate routines
o change beacon+probe response handling to treat the scan table
  more like a scan cache--look for an existing entry before adding
  a new one; this combined with ic_curchan use corrects handling of
  stations that were previously found at a different channel
o move adhoc neighbor discovery by beacon+probe response frames to
  a new ieee80211_add_neighbor routine

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.

11c70aecee ral_init() takes a struct ral_softc as parameter not a struct ifnet.
Fixes a panic that occured when setting the interface parameters while
the interface was associated.

0e8975d715 o Fix a write mbuf-after-free bug. The duration field of the 802.11 header
was written in the old fragmented mbuf chain instead of the defragmented
  one.  Thus, the duration field of outgoing frames was incorrect.

o Only call m_defrag() if the mbuf fragmentation threshold is greater
  than what is currently supported by the driver.

ab581af779 Eliminate unused argument in PCMCIA_CARD macro.
Provide a backwards compatible way to have the extra macro by defining
PCCARD_API_LEVEL 5 before including pccarddevs for driver writers that
want/need to have the same driver on 5 and 6 with pccard attachments.

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.
