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.

2cc12aded0 o fix wpa w/ wme: don't strip the QoS header on recv as tkip requires
it; instead pass the space occupied by the header down into the

dd70e17b12 Revise crypto api lightly to improve group key handling:
o don't pre-assign key index to the global key table entries so device
  has a chance to decide what to use
o make ieee80211_crypto_newkey take the desired flags as an argument
  instead of wacking the key structure directly; this eliminates a
  bunch of code warts
o add a new flag IEEE80211_KEY_GROUP to indicate a key is a WPA Group
  key so devices don't need to guess (temporarily add this flag in the
  ioctl code until we can get wpa_supplicant+hostapd updated)
o shuffle IEEE80211_KEY_* bits to move flags used internally to the high
  nibble of the flags word

c788ca3e3c Recently, it was reported to me that you could provoke a double fault
panic with the NDISulator if you did "ifconfig ndis0 10.0.0.1/24,"
whereas "ifconfig ndis0 10.0.0.1/24 up" worked fine. The double fault
was caused by the ifconfig thread running out of kernel stack space.
(This was partly due to the NDIsulator using a couple of big buffers on
the stack, but even after fixing that the double fault persisted.)

It turns out that ndis_init() is called in both cases, but in the first
case the code path passes through ieee80211_ioctl(), and it turns out
ieee80211_ioctl() consumes a whopping 2400 bytes of stack space.
Apparently, gcc -O2 causes the ieee80211_ioctl_get80211() routine to
be inlined into ieee80211_ioctl(), and for some reason which I do not
fully understand, this causes ieee80211_ioctl() to consume an extra 2K
of stack space.

To prevent this overly agressive optimization, ieee80211_ioctl_get80211()
is now declared with __attribute__ ((noinline)). With this change,
ieee80211_ioctl() now only reserves about 200 bytes of stack instead of 2400.
