When team_notify_peers and team_mcast_rejoin are called, they both reset
their respective .count_pending atomic variable. Then when the actual
worker function is executed, the variable is atomically decremented.
This pattern introduces a potential race condition where the
.count_pending rolls over and the worker function keeps rescheduling
until .count_pending decrements to zero again:
THREAD 1 THREAD 2

team_notify_peers(teamX)
atomic_set count_pending = 1
schedule_delayed_work
team_notify_peers(teamX)
atomic_set count_pending = 1

atomic_dec_and_test
count_pending = 0
(return)
schedule_delayed_work
team_notify_peers_work
atomic_dec_and_test
count_pending = -1
schedule_delayed_work
(repeat until count_pending = 0)
Instead of assigning a new value to .count_pending, use atomic_add to
tack-on the additional desired worker function invocations.

Commit f7f1de51ed ("net: dsa: start and stop the PHY state machine")
add calls to phy_start() in dsa_slave_open() respectively phy_stop() in
dsa_slave_close().
We also call phy_start_aneg() in dsa_slave_create(), and this call is
messing up with the PHY state machine, since we basically start the
auto-negotiation, and later on restart it when calling phy_start().
phy_start() does not currently handle the PHY_FORCING or PHY_AN states
properly, but such a fix would be too invasive for this window.

SKB_FCLONE_UNAVAILABLE has overloaded meaning depending on type of skb.
1: If skb is allocated from head_cache, it indicates fclone is not available.
2: If skb is a companion fclone skb (allocated from fclone_cache), it indicates
it is available to be used.
To avoid confusion for case 2 above, this patch replaces
SKB_FCLONE_UNAVAILABLE with SKB_FCLONE_FREE where appropriate. For fclone
companion skbs, this indicates it is free for use.
SKB_FCLONE_UNAVAILABLE will now simply indicate skb is from head_cache and
cannot / will not have a companion fclone.

net: Generic UDP Encapsulation
Generic UDP Encapsulation (GUE) is UDP encapsulation protocol which
encapsulates packets of various IP protocols. The GUE protocol is
described in http://tools.ietf.org/html/draft-herbert-gue-01.
The receive path of GUE is implemented in the FOU over UDP module (FOU).
This includes a UDP encap receive function for GUE as well as GUE
specific GRO functions. Management and configuration of GUE ports shares
most of the same code with FOU.
For the transmit path, the previous FOU support for IPIP, sit, and GRE
was simply extended for GUE (when GUE is enabled insert the GUE
header on transmit in addition to UDP header inserted for FOU).
Semantically GUE is the same as FOU in that the encapsulation (UDP
and GUE headers) that are inserted on transmission and removed on
reception so that IP packet is processed with the inner header.
This patch set includes:
- Some fixes to FOU, removal of IPv4,v6 specific GRO functions
- Support to configure a GUE receive port
- Implementation of GUE receive path (normal and GRO)
- Additions to ip_tunnel netlink to configure GUE
- GUE header inserion in ip_tunnel transmit path
v2:
- Include net/gue.h in patch set
Testing:
I ran performance numbers using netperf TCP_RR with 200 streams,
comparing encapsulation without GUE, encapsulation with GUE, and
encapsulation with FOU.

This patch adds support receiving for GUE packets in the fou module. The

and GUE. To support this a type parameter is added to the fou netlink
parameters.
For a GUE socket we define gue_udp_recv, gue_gro_receive, and
gue_gro_complete to handle the specifics of the GUE protocol. Most

commit 03b8c7b623 ("futex: Allow
architectures to skip futex_atomic_cmpxchg_inatomic() test") added the
HAVE_FUTEX_CMPXCHG symbol right below FUTEX. This placed it right in
the middle of the options for the EXPERT menu. However,
HAVE_FUTEX_CMPXCHG does not depend on EXPERT or FUTEX, so Kconfig stops
placing items in the EXPERT menu, and displays the remaining several
EXPERT items (starting with EPOLL) directly in the General Setup menu.
Since both users of HAVE_FUTEX_CMPXCHG only select it "if FUTEX", make
HAVE_FUTEX_CMPXCHG itself depend on FUTEX. With this change, the
subsequent items display as part of the EXPERT menu again; the EMBEDDED
menu now appears as the next top-level item in the General Setup menu,
which makes General Setup much shorter and more usable.

Intel Wired LAN Driver Updates 2014-10-02
This series contains updates to fm10k, igb, ixgbe and i40e.
Alex provides two updates to the fm10k driver. First reduces the buffer
size to 2k for all page sizes, since most frames only have a 1500 MTU
so supporting a buffer size larger than this is somewhat wasteful.
Second fixes an issue where the number of transmit queues was not being
updated, so added the lines necessary to update the number of transmit
queues.
Rick Jones provides two patches to convert ixgbe, igb and i40e to use
dev_consume_skb_any().
Emil provides two patches for ixgbe, first cleans up a couple of wait
loops on auto-negotiation that were not needed. Second fixes an issue
reported by Fujitsu/Red Hat, which consolidates the logic behind the
dynamically setting of TXDCTL.WTHRESH depending on interrupt throttle
rate (ITR) setting regardless of BQL.
Ethan Zhao provides a cleanup patch for ixgbe where he noticed a
duplicate define.
Bernhard Kaindl provides a patch for igb to remove a source of latency
spikes by not calling code that uses mdelay() for feeding a PHY stat
while being called with a spinlock held.
Todd bumps the igb version based on the recent changes.

Validation of skb can be pretty expensive :
GSO segmentation and/or checksum computations.
We can do this without holding qdisc lock, so that other cpus
can queue additional packets.
Trick is that requeued packets were already validated, so we carry
a boolean so that sch_direct_xmit() can validate a fresh skb list,
or directly use an old one.
Tested on 40Gb NIC (8 TX queues) and 200 concurrent flows, 48 threads
host.
Turning TSO on or off had no effect on throughput, only few more cpu
cycles. Lock contention on qdisc lock disappeared.
Same if disabling TX checksum offload.

Instead of building all of the xHCI code into a single module, separate
it out into the core (xhci-hcd), PCI (xhci-pci, now selected by the new
config option CONFIG_USB_XHCI_PCI), and platform (xhci-plat) drivers.
Also update the PCI/platform drivers with module descriptions/licenses
and have them register their respective drivers in their initcalls.

In preparation for allowing the xHCI host controller drivers to be built
as separate modules, export symbols from the xHCI core that may be used
by the host controller drivers.

Instead of calling xhci_compliance_mode_recovery_timer_quirk_check() again
in the PCI suspend path, just check for XHCI_COMP_MODE_QUIRK which will
have been set based on xhci_compliance_mode_recovery_timer_quirk_check()
in xhci_init().

Since the struct hc_driver is mostly the same across the xhci-pci,
xhci-plat, and the upcoming xhci-tegra driver, introduce the function
xhci_init_driver() which will populate the hc_driver with the default
xHCI operations. The caller must supply a setup function which will
be used as the hc_driver's reset callback.
Note that xhci-plat also overrides the default ->start() callback so
that it can do rcar-specific initialization.

The current version of the et131x driver has been accepted into the
main tree at /drivers/net/ethernet, so it can now be removed from
staging.
The MAINTAINERS entry has not been touched here, as the patch to
add the driver to drivers/net modifies it correctly.
