frame being sent is to be ack'd and hasn't been filtered by the h/w;
this insures we don't pass in tx descriptors that have no meaningful
state (e.g. mcast/bcast frames are not acked and so have no tx retry
counts)

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.

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
