[correct would have been howmany(...), use IEEE80211_CHAN_BYTES,
which is used in the other ioctl method. While here s/u_char/u_int8_t/

b307a01ecd Revamp ieee80211_get_rate. Now it does not use the rateset in the
ic->ic_bss, but it uses the rateset in its new ieee80211_node
argument, instead.  If the rate is fixed by ic->ic_fixed_rate, but
the fixed rate is not in the node's rateset, choose a reasonable
default: prefer the lowest basic rate or, if there is no basic
rate, prefer the lowest rate, period.

Change a printf complaint to a debug message.

Adapt drivers to suit new ieee80211_get_rate calling convention.

XXX I really need to replace ieee80211_get_rate with a bitrate
XXX adaptation algorithm.  Soon, soon....

25e9e914b4 Miscellaneous ath(4) and net80211 updates and bug-fixes coming from
sam@ and various open source repositories:

ath(4):

        Ignore "phantom" beacon misses: should stabilize connections
        to access points (no more ceaseless link-UP/DOWN indications).
        Also, re-synchronize beacon timer using the TSF in the
        first beacon received after joining a BSS---this should
        also help suppress spurious beacon misses.  I am hopeful
        that this will help ath(4) lossage reported by perry@ and
        smb@.

        Add new configuration through sysctl.

        Use a shorter calibration interval until IQ calibration
        finishes.

        Report antenna noise through radiotap.

        Rudiments of Radar Detection / Dynamic Frequency Selection.

        Update to HAL version 0.9.16.13.

        Update open sources for changes to the HAL API.

        Add HALs for additional architectures: add big-endian ELF
        HALs for sparc64 and for PowerPC.  Also add a Alpha HAL.
        These new HALs are untested under NetBSD.

ath(4) + net80211:

        Make the multicast transmit rate configurable by ioctl.

        Miscellaneous bug fixes.

e597d2a713 Simplify SIOCS80211BSSID, making it work just like IEEE80211_IOC_BSSID.
The upshot is that the interface is *always* reset when a BSSID is
configured.  While I am here, rename unwieldy empty_macaddr variable
to zerobssid.

1e9e4aceb7 Rewrite ieee80211_get_rate using clue from sys/dev/ic/athrate-sample.c:
Change -1 to named constant IEEE80211_FIXED_RATE_NONE.  ic_fixed_rate
is an index into the ic_sup_rates table, so lookup a fixed rate
there and search the ni->ni_rates table for it.

13283d6e4f In atw(4), use ieee80211_compute_duration() to compute IEEE 802.11
Duration and PLCP Length fields, and delete the abominable
atw_frame_setdurs() subroutine.

Make rtw(4) use the new ieee80211_compute_duration() calling
convention.

Add an ieee80211_key argument to ieee80211_compute_duration() and
lightly constify arguments.  Get the crypto header length from the
key argument instead of blithely assuming a WEP header.  Add some
inline documentation.  Account for data padding (IEEE80211_F_DATAPAD).

8e41de9845 Always record a change of the BSS node's BSSID, even if a desired
BSSID is set.

In IBSS mode, if the BSS node's BSSID changes, and a desired BSSID
is *not* set, make a RUN->RUN transition to give the driver an
opportunity to reprogram its BSSID filter.  This fixes a bug where
both wlanctl(8) and ifconfig(8) indicated that an interface had
joined a new BSS, but no packets would get through, except in
promiscuous mode, because the hardware still filtered packets based
on the old BSSID.

3d578b96da In adhoc mode, mark the "BSS" node's (ic->ic_bss) change of BSSID.
If the operator did not configure a "desired BSSID," then we simply
adopt the BSS node's new BSSID.  If the operator configured a
"desired BSSID," the new BSSID is (probably) not the desired one,
so start scanning for it.

Note that a change of BSSID will occur as two ad hoc networks merge.

5e8176f5d5 In ieee80211_init_neighbor, delete unsupported rates from an adhoc
node.  It's the right thing to do, but it is of pressing importance
because SampleRate's ath_rate_ctl_reset() will convert an unsupported
rate to an invalid rate-index of 0xff, and pass the index to
ath_hal_computetxtime().  ath_hal_computetxtime() does not tolerate
an invalid index; the CPU traps a divide-by-zero fault in
ath_hal_computetxtime().

cd662cea95 Set the "special" struct ieee80211_channel pointer, IEEE80211_CHAN_ANYC,
to 0x1 instead of 0xffff, so the kernel will trap accidental
dereferences.  I don't set IEEE80211_CHAN_ANYC to NULL because it
may have a distinct meaning in net80211.  Thanks to Steve Woodford
for pointing out that 0xffff may be a valid kernel memory address
on x86.

461cd4dbb5 Repair adhoc mode.
1 Complete initialization of "faked up" ieee80211_nodes,
          whose capabilities and other fields are wrong, when we
          first receive a beacon or probe response from the
          corresponding neighbor.  This entails factoring
          ieee80211_init_neighbor out of ieee80211_add_neighbor.

        2 In adhoc mode, ic->ic_bss is present in the neighbors
          table, ic->ic_sta, and it is not necessarily the wrong
          node on which to mark statistics for a rx'd packet.  Do
          not reject ic->ic_bss and fake-up a new node without
          comparing its MAC address with the address of the sender
          in the rx'd packet.  This fixes a memory leak.
