When we receive an OGM from from a node for the first time, the last_real_seqno
field of the orig_node structure has not been initialised yet. The value of this
field is used to compute the current ogm-seqno window and therefore the
protection mechanism will probably drop the packet due to an out-of-window error.
To avoid this situation this patch adds a check to skip the window protection
mechanism if no neighbour nodes have already been added. When the first
neighbour node is added, the last_real_seqno field is initialised too.

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!
