Like other vendors, p54* devices have a checksum for
the EEPROM descriptor data. This patch enhances the
parser code to generate and verify the data fields,
before initializing the radio-chip on the card.

Note:
	If you have to bootstrap an alternative EEPROM image
	for your device and you don't know how to generate a
	valid crc ccitt checksum, you should take a look at:
	http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git

	The "checksum" utility loads a binary p54 EEPROM blob
	(use the -f switch, to skip the check) and applies
	the correct crc automatically.

This function analyses only its single, value-passed
argument, and has no side effects. Thus it can be
const, which makes mac80211 smaller, for example:

 362518	  16720	    884	 380122	  5ccda	mac80211.ko (before)
 362358	  16720	    884	 379962	  5cc3a	mac80211.ko (after)

a 160 byte saving in text size, and an optimisation
because the function won't be called as often.

rt2x00 was keeping a copy of ieee80211_rx_status embedded
into the rt2x00_dev structure. For each RX frame, this structure
was copied into the skb->cb where mac80211 would handle it further.

However at the moment only the fields current band, and frequency
were updated. Whereas the band was already provided directly within
the rt2x00_dev structure. Save a memcpy action, and reduce memory
a bit, by adding a curr_freq field to rt2x00_dev, and completely
remove the ieee80211_rx_status structure from rt2x00_dev.

The TX_STA_FIFO register which is used for per-frame TX frame
status reporting is also valid on rt2800usb. We can move the
rt2800pci_txdone function into rt2800lib where it can also
be used by rt2800usb.

rt2800usb needs to overwrite the txdone work handler to
a different function.

Both rt2800usb as rt2800_txdone need to take into account
that IO failures can occur while uploading the URB, which
means that when obtaining the new entry the IO status must
be checked.

The only reason why the write_tx_data callback function
is needed inside the driver, is because the location of
the TXWI descriptor is different on PCI and USB hardware.
Except for the beacon, where the TXWI is always at the
start of the SKB buffer.

In both cases the drivers write_tx_data function only
wrap around the function rt2800_write_txwi. Move write_tx_data
completely into the rt2800lib library, and add a callback
function to obtain the TXWI pointer.
