Add ethtool -K knob to control LRO in firmware.
LRO path is completely separated from GRO, LRO packets
are still fed with netif_receive_skb().

mwl8k: fix firmware command serialisation

The current mwl8k_priv->fw_lock spinlock doesn't actually protect
against multiple commands being submitted at once, as it is not kept
held over the entire firmware command submission.  And since waiting
for command completion sleeps, we can't use a spinlock anyway.

To fix mwl8k firmware command serialisation properly, we have the
following requirements:
- Some commands require that the packet transmit path is idle when
  the command is issued.  (For simplicity, we'll just quiesce the
  transmit path for every command.)
- There are certain sequences of commands that need to be issued to
  the hardware sequentially, with no other intervening commands.

This leads to an implementation of a "firmware lock" as a mutex that
can be taken recursively, and which is taken by both the low-level
command submission function (mwl8k_post_cmd) as well as any users of
that function that require issuing of an atomic sequence of commands,
and quiesces the transmit path whenever it's taken.

- MWL8K_WQ_FREE_WORKSTRUCT is never used.

- timeout_ms/txwait_attempts/tx_timeout_ms are never changed from

Adding and removing the DMA header that the mwl8k hardware requires

have enough headroom on the tx path to expand the packet, and we only
ever shrink the packet on the rx path.  (And on both paths we are
guaranteed to be the only user of the skb we are handling.)

This allows removing all of the skb clone handling in the tx and tx

function so that we don't have to look at the multicast address list
itself outside of mwl8k_configure_filter().

mac80211: allow configure_filter callback to sleep

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.

cfg80211: fix deadlock

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.

iwlwifi: fix erroneous use of iwl_rx_packet.len as a length

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.
