Johannes Berg 94778280fa mac80211: provide sequence numbers
I've come to think that not providing sequence numbers for
the normal STA mode case was a mistake, at least two drivers
now had to implement code they wouldn't otherwise need, and
I believe at76_usb and adm8211 might be broken.

This patch makes mac80211 assign a sequence number to all
those frames that need one except beacons. That means that
if a driver only implements modes that do not do beaconing
it need not worry about the sequence number.

Christian Lamparter 40333e4fb4 p54: honour bss_info_changed's short slot time settings
This patch was made on behalf of Johannes request.
"mac80211 and IEEE80211_CONF_SHORT_SLOT_TIME"

Of course, bss_info_changed provides some more useful data.
e.g.: basic_rates, dtim_period, beacon_int and maybe even more.
Everything can be hooked up if it's necessary.

Christian Lamparter cc6de669f6 p54: add lots of useful rx/tx statistics
The firmware can provide lots of useful statistics about noise floor,
mac time and lots of numbers about successful transfers and dropped
frames.

Christian Lamparter a0db663ff1 p54: 32-bit tsf timestamps

as one can see on the huge jump, it's very plausible that firmware does not report the
full 64-bit mac time, just the lower 32bit and some kinds of flags...
Therefore if we want a useful timestamp we have to emulate the high bits.

Christian Lamparter 19c19d54b6 p54: better firmware support
This patch hopefully contains all necessary changes to support
firmwares for all devices up to atleast 2.13.3.0.
(or: LowerMAC Protocol Rev: 5.5 )

And this is a big win, since:
 * newer firmwares are more stable and reliable than the old ones.
 * no problems anymore with packages > 1399 octets (without lowering the MTU).
 * monitor mode finally works on USB for more than just a few seconds.

This patch axes all superfluous parameters and gives most of the magic values appropriate names.

Christian Lamparter 7cb770729b p54: move eeprom code into common library
Both p54pci and p54usb uses a good chunk of device specific code to
get the data from the device's eeprom into the drivers memory.

So, this patch reduces the code size and will it make life easier if
someone wants to implement ethtool eeprom dumping features.

The firmware headers provides the right values for extra head-/tailroom

It's been a long time, but fullmac prism54 driver is still around...
I think we should rename every prism54* in order to avoid some
confusion about "what is actually what" in the future ;-).

Larry Finger eda0c003d1 p54: Fix for TX sequence number problem
Following "mac80211: fix TX sequence numbers", if a packet
has the IEEE80211_TX_CTL_ASSIGN_SEQ assigned, a sequence number must be
supplied, either by hardware or software. AFAIK, no such hardware exists
for the p54, thus it must be done in software. With this patch, a connection
qith p54usb is stable, whereas the interface went off-line in 2-3 hours
without this change. Note that this code will have to be reworked for proper
sequence numbers on beacons. In addition, the sequence number has been placed
in the hardware state, not the vif state.

Larry Finger 6041e2a08c p54: Fix potential concurrent access to private data
Experience with the rtl8187 driver has shown that mac80211 can make
calls to the config callback routine in rapid succession. This patch
creates a mutex that protects the private data in several of the routines
called by mac80211.
