ea416a793d cfg80211: report userspace SME connected event properly
Instead of hacking the event reporting into the
__cfg80211_connect_result() function which is also
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.

Thanks to Zhu Yi for pointing out that the code is
somewhat convoluted and doesn't warn when it should.

86b2892a22 b43: LP-PHY: Remove BROKEN from B43_PHY_LP
Larry has reported success getting scan data with an LP-PHY device,
so it's probably time to release LP-PHY support for testing.

Also disable 802.11a support for now, as 802.11a currently causes
the driver to panic on startup (NULL pointer dereference).

0ff6ce7b36 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.

396887a2b2 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.

Short guard interval support is a local per-station parameter not a global

per-station HT capabilities during rate selection.

28bd723bba iwlwifi: configure HT40 channels in iwl_mac_config
As indicated by note in iwl_ht_conf, some HT parameters are set on association
(e.g., channel width) and some vary over time (HT protection mode) and per
station (e.g., short GI support).  The global parameters should be set in
iwl_mac_config and the local/varying parameters in iwl_ht_conf.

This patch moves the channel width configuration from iwl_ht_conf to
iwl_mac_config, and defers further cleanup of the local/global conflation for a
later patch.

This fixes a bug in using HT40 channels in some modes.

This patch fixes a number of issues in iwl_rx_reply_rx and

- Unify code handling rx_phy_res in SKB or cached to eliminate redundancy and
remove potential NULL pointer accesses
- Replace magic number with proper constant
- Optimize functions by moving early exit conditions before computation
- Comment code and improve some variable names
- Remove redundant computation in iwl_pass_packet_to_mac80211 by passing in the
correct, already-computed arguments.

b85daa5324 vlan: adds fcoe offload related net_device_ops and updates fcoe_ddp_xid field
Adds fcoe offload related net_device_ops functions vlan_dev_fcoe_ddp_setup
and vlan_dev_fcoe_ddp_done, their implementation simply calls real eth device
net_device_ops for FCoE DDP setup and done operations.

Updates VLAN netdev field value for fcoe_ddp_xid from real eth device netdev.

Above changes are required for fcoe DDP offload working on a VLAN interface.

0ea065e52e sky2: fix pause negotiation
The sky2 driver combines auto speed negotiation with automatic negotiation
of pause parameters; but the ethtool interface expects them to be
split. This patch allows autonegotiation to be used for speed, but
manually disable flow control.

481cea4a4d sky2: lock less transmit completion
Transmit completion can safely run lockless against transmit start.
In the normal case, completion is done from NAPI and only looks
at elements that are at the tail of the ring.  When doing shutdown
or reset, the transmiter should be completely block by NAPI disable
and blocking of transmit queue. 

Based on earlier work by Mike McCormack.
