The driver does not always use the same timing for what looks like
the same operations.
- DCR0
Use the same udelay everywhere for reset. Upper bound is 100 us.
- DCR9
Use 5us delay for srom clock. 1us delay for phy_write_1bit (writes
PHY_DATA_[01]) are not changed as they stay withing a 2,5MHz MDIO
clock range.

We get two timing related fields for each bss from firmware in scan
results.
1) timestamp - Actual timestamp information in probe response/beacon
2) network_tsf - firmware's TSF value at the time the beacon or probe
response was received.
Both are needed while associating by firmware.
The patch takes care of following things.
1) We should pass "timestamp" to cfg80211_inform_bss(), but currently
"network_tsf" is being provided. This error is corrected here.
2) Rename "network_tsf" to "fw_tsf"
3) Make use of u64 variable instead of an array of u8/u32 to save
parsed "timestamp" information.
4) Use timestamp provided to stack in scan results using
cfg80211_inform_bss() while associating. (bss->tsf)
5) Allocate space to save fw_tsf in "priv" of cfg80211_bss
and retrieve it while associating.

As described at
http://article.gmane.org/gmane.linux.kernel.wireless.general/86084
libertas is taking a long time to load because it loads firmware
during module loading.
Add a new API for interface drivers to load their firmware
asynchronously. The same semantics of the firmware table are followed
like before.
Interface drivers will be converted in follow-up patches, then we can
remove the old, synchronous firmware loading function.

Remove the ability to pass module parameters with firmware filenames
for USB and SDIO interfaces.
Remove the ability to pass custom "user" filenames to lbs_get_firmware().
Remove the ability to reprogram internal device memory with a different
firmware from the USB driver (we don't know of any users), and simplify
the OLPC firmware loading quirk to simply placing the OLPC firmware
at the top of the list (we don't know of any users other than OLPC).
Move lbs_get_firmware() into its own file.
These simplifications should have no real-life effect but make the
upcoming transition to asynchronous firmware loading considerably less
painful.

There are connection stalls or very poor throughputs with rt2800
hardware using 802.11n in AP mode since patch "mac80211: retry sending
failed BAR frames later instead of tearing down aggr"[1][2].
Since rt2800 hardware is not able to correctly report the tx status of
BAR frames, this patch removes as workaround the existing error handling
on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails.
As a result, most wifi clients (aside from Intel STAs on Windows)
instead will timeout now the reorder buffer and request the lost frame
again.
The correct solution would be, to tear down BA session on AP side.
This patch was born on the basis of "[RFT] rt2x00: Tear down BA
session on QoS frame failure"[3].
Thanks to Helmut Schaa for his support!

We've never released firmware using the alternatives
mechanism and our build process makes that difficult
anyway. This means that in every file we have ever
built (except maybe by hand for testing) the listed
alternative was 0. Make the alternative field in the
TLVs part of the TLV number (thus expanding that to
32 bits); this gives us more TLV numbers (not really
needed) and more importantly protects against rogue
firmware files that actually do use the alternatives
mechanism -- those will now be rejected since they
don't contain any valid TLVs.

My original idea with this was to adjust the sleep
pattern of the uCode based on the maximum network
latency userspace asked for. Due to nobody wanting
to test it, this logic was disabled by default. It
seems the time has come to remove it, since it's
not only always disabled but there also don't seem
to be any applications that actually request a max
network latency.
