Fixes an issue that smatch pointed out:
1118
1119 key_flags = cpu_to_le16(keyconf->keyidx & STA_KEY_FLG_KEYID_MSK);
^^^^^^^^^^^^^^^
This is s8.
^^^^^^^^^^^^^^^^^^^^^
STA_KEY_FLG_KEYID_MSK is 0x300.
The result after the bitwise AND is always zero because 0xff & 0x300.

The TE_P2P_DEVICE_DISCOVERABLE time event type used for ROC is
assigned low priority in the FW, and thus has low chance of
being scheduled when there are active BSS or GO VMACs (even if
fragmentation is allowed). This is mainly problematic in for
cases where ROC is requested for sending action frames.
To overcome this, use a time event type that has priority equal
to that ot the time event type used by the FW to action scan.

The FW scheduler, schedules the bindings over a session of 128
fragments (each is 4 TU long). The quota command should allocate
all the session fragments between all the bindings that require quota
allocation. Currently, use static allocation, where the fragments
are equally distributed between all data bindings.
Note, that not allocating all the session's fragments might cause
the FW scheduler to leave the medium unused.

When a HP ProLiant DL980 G7 Server boots a regular kernel,
there will be intermittent lost interrupts which could
result in a hang or (in extreme cases) data loss.
The reason is that this system only supports x2apic physical
mode, while the kernel boots with a logical-cluster default
setting.
This bug can be worked around by specifying the "x2apic_phys" or
"nox2apic" boot option, but we want to handle this system
without requiring manual workarounds.
The BIOS sets ACPI_FADT_APIC_PHYSICAL in FADT table.
As all apicids are smaller than 255, BIOS need to pass the
control to the OS with xapic mode, according to x2apic-spec,
chapter 2.9.
Current code handle x2apic when BIOS pass with xapic mode
enabled:
When user specifies x2apic_phys, or FADT indicates PHYSICAL:
1. During madt oem check, apic driver is set with xapic logical
or xapic phys driver at first.
2. enable_IR_x2apic() will enable x2apic_mode.
3. if user specifies x2apic_phys on the boot line, x2apic_phys_probe()
will install the correct x2apic phys driver and use x2apic phys mode.
Otherwise it will skip the driver will let x2apic_cluster_probe to
take over to install x2apic cluster driver (wrong one) even though FADT
indicates PHYSICAL, because x2apic_phys_probe does not check
FADT PHYSICAL.
Add checking x2apic_fadt_phys in x2apic_phys_probe() to fix the
problem.

When trying to connect to an AP that advertises HT but not
VHT, the mac80211 code erroneously uses the configuration
from the AP as is instead of checking it against regulatory
and local capabilities. This can lead to using an invalid
or even inexistent channel (like 11/HT40+).
Additionally, the return flags from downgrading must be
ORed together, to collect them from all of the downgrades.
Also clarify the message.

alignment.
To allow both of protocol-specific data and device-specific data
attached with neighbour entry, and to eliminate size calculation
cost when allocating entry, sizeof protocol-speicic data must be
multiple of NEIGH_PRIV_ALIGN. On 64bit archs,
sizeof(struct dn_neigh) is multiple of NEIGH_PRIV_ALIGN, but on
32bit archs, it was not.
Introduce NEIGH_ENTRY_SPACE() macro to ensure that protocol-specific
entry-size meets our requirement.

Pablo Neira Ayuso says:
====================
The following patchset contains Netfilter/IPVS fixes for 3.8-rc7, they are:
* Fix oops in IPVS state-sync due to releasing a random memory area due
to unitialized pointer, from Dan Carpenter.
* Fix SCTP flow establishment due to bad checksumming mangling in IPVS,
from Daniel Borkmann.
* Three fixes for the recently added IPv6 NPT, all from YOSHIFUJI Hideaki,
with an amendment collapsed into those patches from Ulrich Weber. They
fiix adjustment calculation, fix prefix mangling and ensure LSB of
prefixes are zeroes (as required by RFC).
Specifically, it took me a while to validate the 1's complement arithmetics/
checksumming approach in the IPv6 NPT code.

David Ward says:
====================
The Linux kernel currently implements the GARP VLAN Registration
Protocol (GVRP) from IEEE 802.1Q-1998 (applicant-only participant).
When the GVRP flag is set for a VLAN interface on a Linux host, the
host advertises its membership in the VLAN to the attached bridge/
switch, so that it is not necessary to manually configure the bridge/
switch port to participate in the VLAN.
GVRP has been superseded by the Multiple VLAN Registration Protocol
(MVRP) in IEEE 802.1Q-2011, which addresses scalability concerns about
the earlier protocol. The following patches add support for MVRP to
the Linux kernel and iproute2 utility. They are based largely off of
the existing implementation of GVRP, but have been modified for the
new PDU structure and state machine.
This implementation was tested with two Juniper EX4200 switches.

Michael S. Tsirkin says:
====================
At the moment, macvtap crashes are observed if macvtap is attached
to an interface with LRO enabled.
The crash in question is BUG() in macvtap_skb_to_vnet_hdr.
This happens because several drivers set gso_size but not gso_type
in incoming skbs.
This didn't use to be the case: with intel cards on 3.2 and older
kernels, with qlogic - on 3.4 and older kernels, so it's a regression if
not a recent one.
The following patches fix this for qlogic, broadcom and intel drivers.
I tested that the patch fixes the crash for ixgbe but
don't have qlogic/broadcom hardware to test.
I also only tested TCPv4.
Please review, and consider for 3.8.
Changes from v1:
- added missing htons as suggested by Eric
- backported the relevant bits from
cbf1de72324a8105ddcc3d9ce9acbc613faea17e for bnx2x

In LRO mode, bnx2x set gso_size but not gso type.
This leads to crashes in macvtap.
Commit cbf1de72324a8105ddcc3d9ce9acbc613faea17e
queued for 3.9 includes a more complete fix.
This is a minimal patch to avoid the crash, for 3.8.
