Mesh uses the tx failure average to compute the (m)path metric.  This used to
be done inside the rate control module.  This patch breaks the dependency
between the mesh stack and the rate control algorithm.  Mesh will now work
independently of the chosen rate control algorithm.

The mesh stack keeps a moving average of the average transmission losses for
each mesh peer station.  If the fail average exceeds a certain threshold, the
peer link is marked as broken.

rt2800pci can handle different retry rates,
it will always step 1 rate down after a failed

Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.

A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

Instead of hacking the event reporting into the

invoked by others, set up things correctly and then
invoke that function, so that it can do more sanity
checking.

Also, it is currently not possible to get a ROAMED
event from the userspace SME anyway since we send
out a DISCONNECTED event when it disassociates and
then a new CONNECTED event on the next association.

When removing an interface with nl80211, cfg80211 will
deadlock in the netdev notifier because we're already
holding rdev->mtx and try to acquire it again to verify
the scan has been done.

This bug was introduced by my patch
"cfg80211: check for and abort dangling scan requests".

To fix this, move the dangling scan request check into
wiphy_unregister(). This will not be able to catch all
cases right away, but if the scan problem happens with
a manual ifdown or so it will be possible to remedy it
by removing the module/device.

Additionally, add comments about the deadlock scenario.

The field called 'len' in struct iwl_rx_packet is in fact not just a length
field but also includes some flags from the flow handler.  In several places
throughout the driver, this causes incorrect values to be interpreted as
lengths when the field is improperly masked.

In most situations the improper use is for debugging output, and simply results
in an erroneous message, such as:

[551933.070224] ieee80211 phy0: I iwl_rx_statistics Statistics notification received (480 vs -1367342620).

which should read '(480 vs 484)'.

In at least one case this could case bad things to happen:

void iwl_rx_pm_debug_statistics_notif(struct iwl_priv *priv,
                                      struct iwl_rx_mem_buffer *rxb)
{
        struct iwl_rx_packet *pkt = (struct iwl_rx_packet *)rxb->skb->data;
        IWL_DEBUG_RADIO(priv, "Dumping %d bytes of unhandled "
                        "notification for %s:\n",
                        le32_to_cpu(pkt->len), get_cmd_string(pkt->hdr.cmd));
        iwl_print_hex_dump(priv, IWL_DL_RADIO, pkt->u.raw, le32_to_cpu(pkt->len)
);
}
EXPORT_SYMBOL(iwl_rx_pm_debug_statistics_notif);

Given the rampant misuse of this field without proper masking throughout the
driver (every use but one), this patch renames the field from 'len' to
'len_n_flags' to reduce confusion.  It also adds the proper masking when
this field is used as a length value.
