ca92652af7 Fix ucastkey teardown for drivers that plumb clear keys or similar
(e.g. ath): we must check the key index and not whether the key
points at a cipher other than "undef".  This looks like it's been
broken for a while.  Might be worth adding an explicit clear cipher
at some point though this would require changes to the usage of
IEEE80211_KEY_UNDEFINED.

31378b1c87 Fix definition of IEEE80211_CHAN_MAX; it was defined as 255 but
really was meant to be 256.  Adjust usage accordingly and replace
bogus usage of this value in checking IEEE channel #'s.

NB: this causes an ABI change; ifconfig must be recompiled

1b999d643c Replace adhoc checks in ieee80211_start with a per-node flag that
indicates if an association id is required before outbound traffic
is permitted.  This cleans up the previous change that broke mcast
traffic "to the stack" in ap mode as a side effect.

4b79449e2f Rather than using hidden includes (with cicular dependencies),
directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.

For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

d6f57961a8 Fix checks for fast frames negotiation. ni_ath_flags holds the
capabilities reported by the ap.  These need to be cross-checked
against the local configuration in the vap.  Previously we were
only checking the ap capabilities which meant that if an ap reported
it was ff-capable but we were not setup to use them we'd try to do
ff aggregation and drop the frame.

There are a number of problems to be fixed here but applying this
fix immediately as the problem causes all traffic to stop (and has
not workaround).

e66b0905fc o use the new association callback to notify the driver when joining a bss

8f4addc0a8 Fix joining an 11b BSS: scanning is normally done using 11g channels
(unless explicitly locked to mode 11b) so when we join the bss the
channel attached to the scan cache entry may need to be demoted.

o demote to 11b if the ap is advertising 11b rates
o skip the ap if it's 11b but we're locked to 11g (could consider this
  advisory but for now treat it as mandatory)
o handle an odd edge case, if there is a fixed transmit rate for 11g
  then the rate check against the 11b ap will fail, try to demote to
  11b and retry the rate check

8b615593fc Step 1.5 of importing the network stack virtualization infrastructure
from the vimage project, as per plan established at devsummit 08/08:
http://wiki.freebsd.org/Image/Notes200808DevSummit

Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.

Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().

Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).

All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

(*) netipsec/keysock.c did not validate depending on compile time options.

fdabd982e7 Revamp ht ie handling:
o change ieee80211_parse_htcap and ieee80211_parse_htinfo to save only
  internal state obtained from the ie's; no dynamic state such as
  ni_chw is altered
o add ieee80211_ht_updateparams to parse ht cap+info ie's and update
  dynamic node state
o change ieee80211_ht_node_init to not take an htcap ie that is parsed;
  instead have the caller make a separate call as one caller wants to
  parse the ie while another wants to parse both cap+info ie's and
  update state so can better do this with ieee80211_ht_updateparams

These changes fix sta mode state handling where the node's channel
width was shifted to ht20/ht40 prematurely.

01a03542b1 Add current transmit parameters for fixed rate handling so drivers
don't duplicate this.  These are setup according to the role of the
node--the bss node for ap and adhoc modes need to use parameters
that are the least common denomimator of all nodes in the bss;
otherwise we are setting up params for a station joining a bss and
we select those according to the capabilities of the station.

This stuff needs more work as we do extra work due to having setup
in common code paths shared by nodes using both roles.
