Hi Richard,
So you mean that as the "global" function won't be "inlined" by the
compiler as the function is not "static" neither in the same file and
that the jump will be implemented anyway. And this even if the function
is only called at a single location...
This way, if we add a kind or accessors function like the one that you
propose, with the test in it, the branch prediction can play his role
without breaking the processor pipeline as the accessors function will
be inlined by the compiler: Am I right?
So, yes, makes sense. Thanks for the hint.
Regards,

Yes, I could add a sub-attribute in IFLA_INFO_DATA (e.g. the PPP unit).
That'd be enough to make libnl1 happy. But that wouldn't make much
sense if not backported to stable kernel versions. Given that the
netlink message is already properly formatted and that the problem only
appears with an obsolete library, I'm not sure that's worth it.
Proper message parsing is a must, or we'd loose the extensibility
proprety of netlink (which was the fundamental reason for creating it
in the first place). So for now, I prefer to leave the code as is,
unless someone asks me otherwise.

The PCI glue code does not call stmmac_probe_config_dt.
Also any glue driver could override the value set by stmmac_probe_config_dt
before calling stmmac_dvr_probe. So I guess if we want any trustworthy
sanity-checking, it actually has to be done in stmmac_main.c.

Hmmm... I'm not thrilled to have such heuristics, that change memory
behavior when half of the queue size (sk->sk_rcvbuf) is reached.
Most of the win comes from doing a local atomic page-refcnt decrement
oppose to doing a remote CPU refcnf-dec. And as you noticed the
benefit is quite high saving 241 cycles (see [1]). And you patch is
"using" these cycles to copy the packet instead.
This might no be a win in the future. I'm working on a more generic
solution (page_pool) that (as one objective) target this remote recfnt.

To prevent future bugs, please add a comment here:
/* socket refcnt not held, only use for cancellation */
This field is just an opaque token used for cancellation rather than a
struct vsock_sock pointer that we are allowed to dereference. You could
change this field to void *cancel_token to make the code harder to
misuse.

This doesn't work with the VMCI transport. Remember af_vsock.c is
common code shared by all transports.
You need to add a struct vsock_transport->cancel_pkt() callback instead
os a struct virtio_transport->cancel_pkt() callback. And you need to
handle the case where cancel_pkt == NULL if you don't implement it for
VMCI.

We need more information to proceed further.
Without suspend, Are you able to use the tg3 port?
Which Broadcom card are you having in laptop?
Please provide complete tg3 specific logs in dmesg.

How "priv->plat->dma_cfg->pbl" could be equal to 0 if you force it to
DEFAULT_DMA_PBL in "stmmac_probe_config_dt" in case of DT doesn't set

NAK. We do have a way to configure this and that's rtnetlink. Open
vSwitch should use that to configure tunnels. Out of tree modules are
on their own. Upstream kernel does not accommodate out of tree modules.

* [PATCH net-next] openvswitch: fix VxLAN-gpe port can't be created in ovs compat mode
From: Yi Yang @ 2016-12-08 8:20 UTC (permalink / raw)
To: netdev-u79uwXL29TY76Z2rM5mHXA
Cc: dev-yBygre7rU0TnMu66kgdUjQ, jbenc-H+wXaHxf7aLQT0dZR+AlfA
In ovs compat mode, ovs won't use LWT in current kernel, this is to
make sure ovs can work on the old kernels, Linux kernel v4.7 includes
VxLAN-gpe support but many Linux distributions' kernels are odler than
v4.7, this fix will ensure that ovs can create VxLAN-gpe port correctly
on old kernels, it has been verified on Ubuntu 16.04 x86_64 with Linux
kernel 4.4.0-53-generic.
This does touch compat code, but it is necessary as Pravin commented.
Without this fix, ovs can't create VxLAN-gpe port, it is still a VxLAN
port.
vxlan_sys_4790 Link encap:Ethernet HWaddr 72:23:60:c2:8b:8d

TX packets:0 errors:0 dropped:8 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
But with this fix applied, a real L3 port is created

Hi Dave,
I didn't miss your "net-next is closed" email, but it did come as a bit
of a surprise, and due to time-zone differences I didn't have a chance
to react to it until now. We would have had a couple of patches in
bluetooth-next that we'd still have wanted to get to 4.10.
Out of these the most critical one is the H7/CT2 patch for Bluetooth
Security Manager Protocol, something that couldn't be published before
the Bluetooth 5.0 specification went public (yesterday). If these really
can't go to net-next we'll likely be sending at least this patch through
bluetooth.git to net.git for rc1 inclusion.
Johan

* [PATCH v2 2/2] net: rfkill: Add rfkill-any LED trigger
From: Michał Kępień @ 2016-12-08 7:30 UTC (permalink / raw)
To: Johannes Berg, David S . Miller; +Cc: linux-wireless, netdev, linux-kernel
In-Reply-To: <20161208073052.12988-1-kernel@kempniu.pl>
Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any,
which may be useful on laptops with a single "radio LED" and multiple
radio transmitters. The trigger is meant to turn a LED on whenever
there is at least one radio transmitter active and turn it off
otherwise.
Signed-off-by: Michał Kępień <kernel@kempniu.pl>
---
Changes from v1:
- take rfkill_global_mutex before calling rfkill_set_block() in
rfkill_resume(); the need for doing this was previously obviated by
908209c ("rfkill: don't impose global states on resume"), but given
that __rfkill_any_led_trigger_event() is called from
rfkill_set_block() unconditionally, each caller of the latter needs
to take care of locking rfkill_global_mutex,
- declare __rfkill_any_led_trigger_event() even when
CONFIG_RFKILL_LEDS=n to prevent implicit declaration errors,
- remove the #ifdef surrounding rfkill_any_led_trigger_{,un}register()
calls to prevent compilation warnings about functions and a label
being defined but not used,
- move the rfkill_any_led_trigger_register() call in rfkill_init()
before the rfkill_handler_init() call to avoid the need to call
rfkill_handler_exit() from rfkill_init() and thus prevent a section
mismatch.

* [PATCH v2 1/2] net: rfkill: Cleanup error handling in rfkill_init()

Use a separate label per error condition in rfkill_init() to make it a
bit cleaner and easier to extend.

Yes, I noticed that and my assumption was that it was set 'just in case'
to clear any MagicPacket interrupts at probe time.

Cool, I will set ".magic = 1" for r8a7740 in v2.

I briefly considered this but decided against it since I do not have
documentation for all versions of the device and no way to test it. You
tested and confirmed functionality on r8a7740, which leaves:
- sh7734-gether
- sh7763-gether
- sh7757-gether
To figure out if they support MagicPacket in the same fashion as r8a7740
and r8a779x. If anyone have access to documentation or hardware to
confirm this I be more then happy to get rid of the magic flag in favor
och checking for ECSR_MPD in ecsr_value.

Thanks, looking it it now I don't know what I was thinking. I will
changes it for v2.

Thanks, you learn new things everyday. I will move it for v2.

* PROBLEM:
From: Tony @ 2016-12-08 7:01 UTC (permalink / raw)
To: edumazet, davem, netdev
Hello,
NB. This is a re-send. I've been advised to send again as I gather I'm
supposed to receive a URL back.
I am reporting this as requested below:
Anthony Buckley, the issue you are reporting is an upstream one. Could
you please report this problem following the instructions verbatim at
https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate mailing
list (TO: Eric Dumazet, and David S. Miller, CC netdev)?
Please provide a direct URL to your post to the mailing list when it
becomes available so that it may be tracked.
Thank you for your help.
** Changed in: linux (Ubuntu)
Status: Confirmed => Triaged
** Summary changed:
- Network scanner not detected by xsane after upgrade to 16.04
+ Network scanner not detected by xsane after kernel upgrade
Apologies if I have sent this to the wrong area(s). I'm a bit new to this.
Kernel.org format information
[1] One line summary of the problem:
Network scanner not detected by xsane after kernel upgrade
[2] Full description of the problem/report:
The scanner on my 'Epson WF-3520' multi-function is no longer detected
by xsane
(and other scan apps.) when connected wirelessly to the network.
The problem occurs on a Dell 64 bit desktop, an Asus 64 bit laptop and a
Medion 32 bit laptop.
Printing works normally and the scanner is detected if connected via a
USB cable.
To reproduce, I turn on the scanner and start xsane. There is some delay
and then
a 'no devices found' window appears.

* [PATCH] ethtool: add one ethtool option to set relax ordering mode
From: Mao Wenan @ 2016-12-08 6:51 UTC (permalink / raw)
To: netdev, jeffrey.t.kirsher
In-Reply-To: <1481179898-10668-1-git-send-email-maowenan@huawei.com>
This patch provides one way to set/unset IXGBE NIC TX and RX
relax ordering mode, which can be set by ethtool.
Relax ordering is one mode of 82599 NIC, to enable this mode
can enhance the performance for some cpu architecure.
example:
ethtool -s enp1s0f0 relaxorder off
ethtool -s enp1s0f0 relaxorder on
