o purge ath_initkeytable; it's not needed
o add multicast key search support for supporting multiple group keys
(disabled for now; requires updated hal)
o create keycache entry for stations using open auth so they get h/w
antenna management support
o add keycache -> node mapping table; eliminates mac-based lookup in
the net80211 layer
an ap in 11g with protection enabled
o correct rate selection when operating in 11g with protection when no
packets have been sent yet (from John Bicket)
o track api change to get first descriptor and use it to collect the frame
length for calculating the state bin
o add more debugging and shuffle some existing debugging to give more info
o bump version to distinguish bug fixes
to the rate control module for tx complete processing; this enables
rate control algorithms to extract the packet length for xmits that
require multiple descriptors
o mark rx frames including FCS in the payload with the
IEEE80211_RADIOTAP_F_FCS flag
o remove hack to copy 802.11 headers with padding out of line; instead mark
the frames with IEEE80211_RADIOTAP_F_DATAPAD and require applications to
do the work
o split precalculated radiotap flags into tx+rx now that they can be different
Note the full usefulness of these changes depends on updates to applications
that process radiotap data.
o don't reclaim any previous beacon state in ath_beacon_alloc; do it
explicitly in ath_newstate
o reference count the node held in the beacon frame state block
o process ibss merge more intelligently; let the state machine do the
right thing instead of explicitly setting the new bssi id
o explicitly stop tx dma before doing beacon setup to handle the ibss
merge case
o increase the max per-frame tx descriptor count and the number of tx
buffers for forthcoming fast frame support
o correct the max scatter/gather count; it cannot be larger than the
max(tx,rx,beacon) descriptor counts
(fix imported from madwifi by Takanori Watanabe)
o eliminate save/restore of pci registers handled by the system
o eliminate duplicate zero of the softc (noted by njl)
o consolidate common code
MFC after: 1 week
o catch one place where we were not using ath_chan_change to
switch channels; this fixes a problem where the channel
settings were not being correctly reported in captured packets
o return unique channel identification in the channel flags;
ethereal gets confused if you return merged flags (e.g. ofdm,
cck, and 2Ghz) (this is workaround and should be removed if
we can ever cleanup radiotap consumers)
o correct short/long preamble flag state for rx and treat tx
the same--use a new hwflags array that gives us the data
based on the h/w rate index/cookie
o add gross hack to handle radiotap capture of frames that
come in with hardware padding; should be replaced by a
flag in the radiotap header and more smarts in the apps
that decode radiotap data
o lintval is in ms; must convert to TU's for passing to the hal
o roundup to calculate nexttbtt (should look at current tsf and pull the
calculated nextbtt forward but this'll do for now)
o don't or- in HAL_BEACON_RESET_TSF when doing station timer setup; this
is not needed and messes up the sleep timer calcs, though it's unclear
if it mattered as the hal masks these values before use

Fix an apparent bug that caused a compile failure.
ieee80211_iterate_nodes() takes ic->ic_sta as its first argument on the

mismatched argument.

Also, convert integers<->pointers via uintptr_t.
(I think Sam's instructions were for me to commit this. If I
misunderstood, then I apologize in advance.)
o move tx taps from ath_start to ath_tx_start so lots more
state is available to tap
o add tx flags
o add tx rate
o add tx power (constant for the moment)
o add tx antenna state
a new bpf_mtap2 routine that does the right thing for an mbuf
and a variable-length chunk of data that should be prepended.
o while we're sweeping the drivers, use u_int32_t uniformly when
when prepending the address family (several places were assuming
sizeof(int) was 4)
o return M_ASSERTVALID to BPF_MTAP* now that all stack-allocated
mbufs have been eliminated; this may better be moved to the bpf
routines

o fix race condition when processing rx descriptors: because we use
a self-linked descriptor at the end of the rx descriptor list to
avoid rx overruns (which can easily happen for 5212 parts that enable
PHY errors) we must carefully check that a descriptor is "done" by
looking ahead to the next descriptor before believing the done bit
in the current descriptor (this is all handled in the HAL since the
rx descriptor format is chip-specific so we need to pass in two
additional parameters--the physical address of the current descriptor
and the virtual address of the next descriptor in the list)
o check copyout return status for SIOCGATHSTATS ioctl

Folks that want to watch PHY errors can still get the statistics

o don't grab the mutex at the top of ath_detach; it does nothing
useful
o deal with entry to ath_ioctl during detach to disable promiscuous
mode as a result of calling bpfdetach2: cannot call ath_init when
the device is marked invalid as the code isn't prepared to deal
with it (in particular by that time the hal reference may have
been yanked)

o add a 16-deep history buffer to each driver-private node storage that
holds rssi and antenna info for received frames
o override the default per-node "get rssi" method to return an average
rssi value based on samples collected over the last second
o enable beacon reception so even idle systems maintain a running history
of signal quality
This data may also be useful for improving the rate control algorithm.

o mask off interrupt status bits that we don't care about so we don't do
the wrong thing; this fixes a problem where the beacon miss interrupt status
bit is delivered together with other status bits when operating in monitor
mode (we would post a beacon miss swi and then do the wrong thing)

o remove detection of 11g support; no longer needed
