other chips set bit5 of REG_MASTER_CTRL --- this way could save more
power than the former, and the bit should be kept all time.
l2cb 1.x has special setting for L0S/L1

stmmac: verify the dma_cfg platform fields

Recently the dma parameters that can be passed from the platform
have been moved from the plat_stmmacenet_data to the stmmac_dma_cfg.

In case of this new structure is not well allocated the driver can
fails. This is an example how this field is managed in ST platforms

static struct stmmac_dma_cfg gmac_dma_setting = {
        .pbl = 32,
};

static struct plat_stmmacenet_data stih415_ethernet_platform_data[] = {
{
.dma_cfg = &gmac_dma_setting,
.has_gmac = 1,
[snip]

This patch so verifies that the dma_cfg passed from the platform.
In case of it is NULL there is no reason that the driver has to fail
and some default values can be passed. These are ok for all the
Synopsys chips and could impact on performances, only.

batman-adv: skip the window protection test when the originator has no neighbours

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.

mwifiex: corrections in timestamp related code

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.

libertas: add asynchronous firmware loading capability

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

rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe fails

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!

iwlwifi: remove uCode alternatives mechanism

We've never released firmware using the alternatives

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
