The transmit packet descriptor consists of four 32-bit words, with word 3
upper bits overloaded depending upon the condition of its bits 3 and 4.
The driver currently duplicates all word 2 and some word 3 register bit
definitions unnecessarily and also uses a set of nested structures in its
definition of the TPD without good cause. This patch adds a lengthy
comment describing the TPD, eliminates duplicate TPD bit definitions,
and simplifies the TPD structure itself. It also expands the TSO check
to correctly handle custom checksum versus TSO processing using the revised
TPD definitions. Finally, shorten some variable names in the transmit
processing path to reduce line lengths, rename some variables to better
describe their purpose (e.g., nseg versus m), and add a comment or two
to better describe what the code is doing.

The L1 tx packet descriptor expects TCP Header Length to be expressed as a
number of 32-bit dwords. The atl1 driver uses tcp_hdrlen() to populate the
field, but tcp_hdrlen() returns the header length in bytes, not in dwords.
Add a shift to convert tcp_hdrlen() to dwords when we write it to the tpd.
Also, some of our bit assignments are made to the wrong tpd words. Change
those to the correct words.
Finally, since all this fixes TSO, enable TSO by default.

After sampling hundreds of RX frame descriptors,
the results were conclusive:
- The Ralink documentation regarding the SIGNAL and RSSI are wrong.
It turns out that of the 5 BBR registers, we should not use BBR0 and BBR1
for SIGNAL and RSSI respectively, but actually BBR1 and BBR2.
BBR0 does show values, but the exact meaning remains unclear,
but they cannot be translated into a SIGNAL or RSSI field.
BBR3, BBR4 and BBR5 are always 0, so their meaning is unknown.
As it turns out, the reported SIGNAL is the PLCP value, this
in contradiction to what was expected looking at rt2500pci which
only reported the PLCP values for OFDM rates and bitrate values
for CCK rates.
This means we should let the driver raise the flag about the contents
of the SIGNAL field so rt2x00lib can always do the right thing based
on what the driver reports.

We should not write 0 to the beacon sync register during
config_intf() since that will clear out the beacon interval
and forces the beacon to be send out at the lowest interval.
(reported by Mattias Nissler).
The side effect of the same bug was that while working with
multiple virtual AP interfaces a change for any of those
interfaces would disable beaconing untill an beacon update
was provided.
This is resolved by only updating the TSF_SYNC value during
config_intf(). In update_beacon() we disable beaconing
temporarily to prevent fake beacons to be transmitted.
Finally kick_tx_queue() will enable beaconing again.

Some architectures give problems when reading
RX frame descriptor words when the descriptor
is not aligned on a 4 byte boundrary.
Due to optimalizations for the ieee80211 payload
4 byte alignment, it is no longer guarenteed
that the descriptor is placed on the 4 byte
boundrary (In fact, for rt73usb it is absolutely
never aligned to 4 bytes, for rt2500usb it depends
on the length of the payload).
This will copy the descriptor to a 4 byte aligned
location before it is read for the first time.
This will also move the payload data alignment
in rt2x00usb (instead of inside the driver) where
it has always belonged.

This is a change to a previous patch ("iwlwifi: 3945 split tx_complete
to command and packet function") to ensure we do not have hardirq safe
locks (priv->lock in this case) depend on hardirq unsafe locks.
We only call iwl3945_tx_queue_reclaim while in a tasklet so we have to use
the irqsafe version of the function.

atheros hardware has a problem with the rx timestamp of some IBSS beacons when
they caused a TSF update (they have the same BSSID).
the rx timestamp is wrong especially if the beacon frames get bigger than 78
byte (at least on AR5213 and AR5414 hardware). in that case ath5k_extend_tsf()
will assume a rs_tstamp overflow and give us a timestamp too far in the past
which will cause mac80211 to merge IBSS on every beacon (which is not necessary
since the BSSID already matches). but in this case we know that the HW must
have synced to the beacons TSF and the rx timestamp must be later than that so
we can adjust mactime accordingly.
also rename the function to ath5k_check_ibss_tsf() and change comments, since
"hw merge" is better described as a TSF update.

descriptor since they are not accessed by the hardware at all. they just
contain converted information from the hardware descriptor. since they are only
used in the rx and tx tasklets there is also no use to keep them for each

* make struct ath5k_desc clearer by directly including unions of structures,
which correspond to the hardware descriptors of different HW versions (5210
and 5212). before they were casted at onto ath5k_desc at different points
(e.g. ds_hw[2]).
* rename some structures and variable names to make their use clearer, e.g.
struct ath5k_hw_4w_tx_desc to ath5k_hw_4w_tx_ctl.
* substitute "old" with "5210" and "new" with "5212" (eg. rename
ath5k_hw_proc_new_rx_status() to ath5k_hw_proc_5212_rx_status()) because old
and new are relative and we might have a newer structure at some point.
* unify structs ath5k_hw_old_rx_status and ath5k_hw_new_rx_status into one
ath5k_hw_rx_status, because they only differ in the flags and masks.
