rt2x00: Fix rt2400pci signal

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.

rt2x00: Fix basic rate initialization

The basic rate which is configured in the register

Fix this by adding a new flag to the rt2x00_rate structure
and whenever the mode is changed, loop over all available rates
for that band to get the basic rate mask.

rt2x00: Move firmware checksumming to driver

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

ath5k: work around wrong beacon rx timestamp in IBSS mode

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.

[UDP]: Revert udplite and code split.

This reverts commit db1ed684f6c430c4cdad67d058688b8a1b5e607c ("[IPV6]
UDP: Rename IPv6 UDP files."), commit
8be8af8fa4405652e6c0797db5465a4be8afb998 ("[IPV4] UDP: Move

e898d4db2749c6052072e9bc4448e396cbdeb06a ("[UDP]: Allow users to
configure UDP-Lite.").

First, udplite is of such small cost, and it is a core protocol just
like TCP and normal UDP are.

We spent enormous amounts of effort to make udplite share as much code
with core UDP as possible.  All of that work is less valuable if we're
just going to slap a config option on udplite support.

It is also causing build failures, as reported on linux-next, showing
that the changeset was not tested very well.  In fact, this is the
second build failure resulting from the udplite change.

Finally, the config options provided was a bool, instead of a modular
option.  Meaning the udplite code does not even get build tested
by allmodconfig builds, and furthermore the user is not presented
with a reasonable modular build option which is particularly needed
by distribution vendors.

[TIPC]: Enhancements to message header writing

This patch makes two enhancements to the routine used to

    covered by the mask being used.  (Previously, if the new value
    exceeded the size of the mask the extra bits could corrupt
    other fields in the message header word being updated.)

 2) The code has been optimized to minimize the number of run-time
    endianness conversion operations by leveraging the fact that the
    mask (and, in some cases, the value as well) is constant and the

mac80211: always insert key into list

Today I hit one of my new WARN_ONs in the mac80211 code because
a key wasn't being freed correctly. After wondering for a while
I finally tracked it to the fact that STA keys aren't added to
the per-sdata key list correctly, they are supposed to always be
on that list, not just for default keys. This patch fixes that.

b43: verify sta_notify mac80211 callback

This helps verify that nothing bad is going on in mac80211,
it is unfortunately not possible to implement this generically
in mac80211 easily because there we can't assume that we only
have a single vif which b43 currently can assume.
