This patch is the first step towards rate control inside softmac.
The txrates substructure has been extended to provide
different fields for different types of packets (management/data,
unicast/multicast). These fields are updated on association to values
compatible with the access point we are associating to.
Drivers can then use the new ieee80211softmac_suggest_txrate() function
call when deciding which rate to transmit each frame at. This is
immensely useful for ZD1211, and bcm can use it too.
The user can still specify a rate through iwconfig, which is matched
for all transmissions (assuming the rate they have specified is in
the rate set required by the AP).
At a later date, we can incorporate automatic rate management into
the ieee80211softmac_recalc_txrates() function.
This patch also removes the mcast_fallback field. Sam Leffler pointed
out that this field is meaningless, because no driver will ever be
retransmitting mcast frames (they are not acked).

The 802.11 specs state that deauthenticating also implies
disassociating. This patch implements that, which improve the behaviour
of SIOCSIWMLME.

This patch adds the SIOCSIWMLME wext to softmac, this functionality
appears to be used by wpa_supplicant and is softmac-specific.

It currently takes something like 8 seconds to do a scan, because we
spend half a second on each channel. Reduce that time to 20ms per
channel.

This patch adds handling of reassociation to softmac when the AP
requests it. Patch from Larry Finger.

Recently the deauth packet handler was updated to use a deauth packet
struct (identical to the auth packet struct) and this now gives a
warning. This patch updates the code to properly use a deauth struct and
deauth variable.

This patch updates the copyright statements in softmac that I
erroneously added for 2005 only (when we already had 2006).
