The old code misbehaved because it polled card status and always called the
"tx over" code-path.

This also fixes a hard lockup by not allowing and card interrupts while
transferring a TX frame or a command into the card.

Implemented rate adaptation support via 'iwconfig rate' API.  It is now
possible to specify a bit-rate value and append 'auto'.  That will configure
rate adaptation to use all bit-rates equal or lower than than selected value.

Made lbs_cmd_802_11_rate_adapt_rateset a direct command.

    mac80211: move TX info into skb->cb

when compiled with only PIO or only DMA because I forgot to update two
stubs. This patch fixes it.

While figuring out the TKIP problem I found a bug in the code which adds the 11g
rates. It's using sizeof instead of ARRAY_SIZE to terminate the for loop. This makes
it fall off the end of the rates array start into the frequency array instead. Running
"iwlist rate" should show the problem as there will always be 32 rates with the last
few being bogus.

The following patch will fix it.

This patch converts mac80211 and all drivers to have transmit
information and status in skb->cb rather than allocating extra
memory for it and copying all the data around. To make it fit,
a union is used where only data that is necessary for all steps
is kept outside of the union.

This patch modifies struct ieee80211_tx_control to give band
info and the rate index (instead of rate pointers) to drivers.
This mostly serves to reduce the TX control structure size to
make it fit into skb->cb so that the fragmentation code can
put it there and we can think about passing it to drivers that
way in the future.
