There no longer are ISA drivers in the fujitsu directory, so remove the
dependency from the Kconfig.

This is really sad; why don't you write a proper dump parser for ethtool
rather than including markers that make it slightly easier to read hex
dumps?
And when changing the dump format in an incompatible way like this, you
should also bump the version number.

While merging the wireless-next tree into -next there were conflicts in
several headers due to conflicts between various commits from Joe
Perches removing extern from headers in the net-next tree and
development in the wireless tree.
I've resolved this as below (sorry, got some extra stuff that resolved
automatically).

* [PATCH 2/2] ixgbe: enable l2 forwarding acceleration for macvlans
From: Neil Horman @ 2013-10-04 20:10 UTC (permalink / raw)
To: netdev; +Cc: John Fastabend, Andy Gospodarek, David Miller, Neil Horman
In-Reply-To: <1380917405-23801-1-git-send-email-nhorman@tuxdriver.com>
Now that l2 acceleration ops are in place from the prior patch, enable ixgbe to
take advantage of these operations. Allow it to allocate queues for a macvlan
so that when we transmit a frame, we can do the switching in hardware inside the
ixgbe card, rather than in software.

* [PATCH 1/2] net: Add layer 2 hardware acceleration operations for macvlan devices
From: Neil Horman @ 2013-10-04 20:10 UTC (permalink / raw)
To: netdev; +Cc: John Fastabend, Andy Gospodarek, David Miller, Neil Horman
In-Reply-To: <1380917405-23801-1-git-send-email-nhorman@tuxdriver.com>
Add a operations structure that allows a network interface to export the fact
that it supports package forwarding in hardware between physical interfaces and
other mac layer devices assigned to it (such as macvlans). this operaions
structure can be used by virtual mac devices to bypass software switching so
that forwarding can be done in hardware more efficiently.

* [RFC PATCH 0/2 v2] net: alternate proposal for using macvlans with forwarding acceleration
From: Neil Horman @ 2013-10-04 20:10 UTC (permalink / raw)
To: netdev; +Cc: John Fastabend, Andy Gospodarek, David Miller
In-Reply-To: <1380140209-24587-1-git-send-email-nhorman@tuxdriver.com>
Hey all-
heres the next, updated version of the vsi/macvlan integration that we've
been discussing.
Some change notes:
* Changes to the fowarding ops structure - Removed the priv_size field, and
added a flags field. Removal of the priv_size field was accomplished by just
having the add method return a void * and using ERR_PTR and PTR_ERR checks,
which also allows us to allocate memory for the acceleration path in the driver,
which I like. I'm not super happy still with how I'm using the flags (currenly
only used to indicate support for feature sets), but at least we have the flags
now, and they can be exposed to user space via iproute2 or ethtool if need be
* Changes to the Transmit path - Specifically I'm using dev_queue_xmit to send
frames now, which I like as it makes the macvlan subject to the lowerdevs qdisc
configuration.
* Changes to the acceleration fail path behavior - Now if we don't/can't use
acceleration, we just fall back to using the normal macvlan software switch
strategy
* General clenups (some renaming, that I'm not super sure of, but I though
forwarding acceleration (fwd) would be a better prefix than l2 acceleration).
Still a long way to go I think, and lots of tweaking to do, but I didn't want to
keep you waiting John. Anywho, take a look at what I'm doing and feel free to
rip it apart.
Thanks!
Neil

Here you must check again the keys (because of UDP sockets being
SLAB_DESTROY_BY_RCU , this socket might have been freed and reused
elsewhere)

* [PATCH net-next v2 3/3] net: ipv4 only populate IP_PKTINFO when needed

The since the removal of the routing cache computing
fib_compute_spec_dst() does a fib_table lookup for each UDP multicast
packet received. This has introduced a performance regression for some
UDP workloads.
This change skips populating the packet info for sockets that do not have
IP_PKTINFO set.

* [PATCH net-next v2 2/3] udp: Add udp early demux
From: Shawn Bohrer @ 2013-10-04 19:28 UTC (permalink / raw)
To: David Miller; +Cc: netdev, tomk, Eric Dumazet, Shawn Bohrer
In-Reply-To: <1380914896-24754-1-git-send-email-shawn.bohrer@gmail.com>
From: Shawn Bohrer <sbohrer@rgmadvisors.com>
The removal of the routing cache introduced a performance regression for
some UDP workloads since a dst lookup must be done for each packet.
This change caches the dst per socket in a similar manner to what we do
for TCP by implementing early_demux.
For UDP multicast we can only cache the dst if there is only one
receiving socket on the host. Since caching only works when there is
one receiving socket we do the multicast socket lookup using RCU.
For UDP unicast we only demux sockets with an exact match in order to
not break forwarding setups. Additionally since the hash chains may be
long we only check the first socket to see if it is a match and not
waste extra time searching the whole chain when we might not find an
exact match.

* [PATCH net-next v2 1/3] udp: Only allow busy read/poll on connected sockets
From: Shawn Bohrer @ 2013-10-04 19:28 UTC (permalink / raw)
To: David Miller; +Cc: netdev, tomk, Eric Dumazet, Shawn Bohrer
In-Reply-To: <1380914896-24754-1-git-send-email-shawn.bohrer@gmail.com>
From: Shawn Bohrer <sbohrer@rgmadvisors.com>
UDP sockets can receive packets from multiple endpoints and thus may be
received on multiple receive queues. Since packets packets can arrive
on multiple receive queues we should not mark the napi_id for all
packets. This makes busy read/poll only work for connected UDP sockets.
This additionally enables busy read/poll for UDP multicast packets as
long as the socket is connected by moving the check into
__udp_queue_rcv_skb().

* [PATCH net-next v2 0/3] Improve UDP multicast receive latency
From: Shawn Bohrer @ 2013-10-04 19:28 UTC (permalink / raw)
To: David Miller; +Cc: netdev, tomk, Eric Dumazet, Shawn Bohrer
From: Shawn Bohrer <sbohrer@rgmadvisors.com>
The removal of the routing cache in 3.6 had impacted the latency of our
UDP multicast workload. This patch series brings down the latency to
what we were seeing with 3.4.
Patch 1 "udp: Only allow busy read/poll on connected sockets" is mostly
done for correctness and because it allows unifying the unicast and
multicast paths when a socket is found in early demux. It can also
improve latency for a connected multicast socket if busy read/poll is
used.
Patches 2&3 remove the fib lookups and restore latency for our workload
to the pre 3.6 levels.
Benchmark results from a netperf UDP_RR test:
v3.12-rc3-447-g40dc9ab kernel 87961.22 transactions/s
v3.12-rc3-447-g40dc9ab + series 90587.62 transactions/s

* Unicast UDP early demux now requires an exact socket match and only
tests first socket in UDP hash chain.

* [PATCH net-next 08/10] qlcnic: Skip unknown entry type while collecting firmware dump
From: Himanshu Madhani @ 2013-10-04 18:30 UTC (permalink / raw)
To: davem; +Cc: netdev, Dept_NX_Linux_NIC_Driver, Shahed Shaikh, himanshu.madhani
In-Reply-To: <cover.1380937706.git.himanshu.madhani@qlogic.com>
From: Shahed Shaikh <shahed.shaikh@qlogic.com>
o Driver aborts the minidump collection operation when it finds
an unknown entry opcode. This patch skips unknown entry type
and resumes the minidump collection operation.
o Removed a comparision of collected dump size with expected dump size.
Size may differ when driver decides to skip an entry.

* [PATCH net-next 05/10] qlcnic: Remove redundant eSwitch enable commands
From: Himanshu Madhani @ 2013-10-04 18:30 UTC (permalink / raw)
To: davem; +Cc: netdev, Dept_NX_Linux_NIC_Driver, Sony Chacko, himanshu.madhani
In-Reply-To: <cover.1380937706.git.himanshu.madhani@qlogic.com>
From: Sony Chacko <sony.chacko@qlogic.com>
When more than one NIC physical functions are enabled on a port,
eSwitch on that port gets enabled automatically. Driver
need not explicitly enable the eSwitch.

Doesn't the format_host() print exactly the same output as before,

Dave,
Please pull this batch of patches intended for the 3.13 stream!
Regarding the Bluetooth bits, Gustavo says:
"The big work here is from Marcel and Johan. They did a lot of work
in the L2CAP, HCI and MGMT layers. The most important ones are the
addition of a new MGMT command to enable/disable LE advertisement
and the introduction of the HCI user channel to allow applications
to get directly and exclusive access to Bluetooth devices."
As to the ath10k bits, Kalle says:
"Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's
just too much to support it. Michal added support for the new firmware
interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are
minor fixes or cleanups."
And also:
"Major changes are:
* throughput improvements including aligning the RX frames correctly and
optimising HTT layer (Michal)
* remove qca98xx hw1.0 support (Bartosz)
* add support for firmware version 999.999.0.636 (Michal)
* firmware htt statistics support (Kalle)
* fix WEP in AP and IBSS mode (Marek)
* fix a mutex unlock balance in debugfs file (Shafi)
And of course there's a lot of smaller fixes and cleanup."
For the wl12xx bits, Luca says:
"Here are some patches intended for 3.13. Eliad is upstreaming a bunch
of patches that have been pending in the internal tree. Mostly bugfixes
and other small improvements."
Along with that...
Arend and friends bring us a batch of brcmfmac updates, Larry Finger
offers some rtlwifi refactoring, and Sujith sends the usual batch of
ath9k updates. As usual, there are a number of other small updates
from a variety of players as well.
Please let me know if there are any problems!
Thanks,
John
