f3268efa7f Don't read channel list from EEPROM since we were already scanning all
802.11b channels (1-14) regardless of what EEPROM says.

4c4102ec52 Be more robust when handling Rx interrupts. If we can't allocate and DMA map
a new mbuf, just discard the received frame and reuse the old mbuf.
This should fix kernel panics on high network traffic.

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.

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.

d365f9c760 Cleanup beacon/listen interval handling:
o separate configured beacon interval from listen interval; this
  avoids potential use of one value for the other (e.g. setting
  powersavesleep to 0 clobbers the beacon interval used in hostap
  or ibss mode)
o bounds check the beacon interval received in probe response and
  beacon frames and drop frames with bogus settings; not clear
  if we should instead clamp the value as any alteration would
  result in mismatched sta+ap configuration and probably be more
  confusing (don't want to log to the console but perhaps ok with
  rate limiting)
o while here up max beacon interval to reflect WiFi standard

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.
