* [PATCH 02/12] protocol.h: Remove extern from function prototypes
From: Joe Perches @ 2013-09-22 17:32 UTC (permalink / raw)
To: netdev; +Cc: David S. Miller, linux-kernel
In-Reply-To: <b692aba58032f629907ea2d462c99b87906645ca.1379870986.git.joe@perches.com>
There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

* [PATCH 05/12] request_sock.h: Remove extern from function prototypes
From: Joe Perches @ 2013-09-22 17:32 UTC (permalink / raw)
To: netdev; +Cc: David S. Miller, linux-kernel
In-Reply-To: <b692aba58032f629907ea2d462c99b87906645ca.1379870986.git.joe@perches.com>
There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

* Bug - regression - Via velocity interface coming up freezes kernel
From: Dirk Kraft @ 2013-09-22 17:28 UTC (permalink / raw)
To: netdev; +Cc: Julia Lawall
Hi,
I observe problems with my machine freezing when bringing up the
network interface (via velocity based). Detailed report below.
First message was rejected because of html. Julia Lawall, sorry about
sending multiple copies.
[1.] One line summary of the problem:
Via_velocity interface coming up freezes kernel - WARNING: CPU: 0 PID:
1529 at /build/buildd/linux-3.11.0/kernel/softirq.c:159
local_bh_enable+0x60/0x90()
[2.] Full description of the problem/report:
Bringing up the network interface (using ifup) serviced by the
via_velocity driver the machine freezes once an ip address is assigned
via dhcp. No further interaction, neither via the just brought up
interface nor the serial console, is possible. A git bisect shows that
this behaviour was introduced with
2fdac010bdcf10a30711b6924612dfc40daf19b8.
During some of the freezes a kernel warning is printed to syslog. I
was unable to see this with 3.12.0-rc1. I was able to observe this
with v3.11-rc6 and different ubuntu kernels. The warning looks like:
WARNING: CPU: 0 PID: 1529 at
/build/buildd/linux-3.11.0/kernel/softirq.c:159
local_bh_enable+0x60/0x90(). Detailed message under point 10.
The second network interface on the board (using the via_rhine driver)
does not show this behaviour. The board in question is a via epia
sn18000g.
[3.] Keywords (i.e., modules, networking, kernel):
[4.] Kernel version (from /proc/version):
Linux version 3.12.0-031200rc1-generic (apw@gomeisa) (gcc version

[5.] Output of Oops.. message (if applicable) with symbolic
information resolved (see Documentation/oops-tracing.txt)
[6.] A small shell script or example program which triggers the
problem (if possible)
[7.] Environment

Because this bug is shadowed by another bug
(https://lkml.org/lkml/2013/8/3/40) I had to apply this patch
(http://lists.freedesktop.org/archives/dri-devel/2013-August/042668.html)
to the versions that would not compile to do the above bisect.

drivers/net/ethernet/via/via-velocity.c: update napi implementation
Drivers supporting NAPI should use a NAPI-specific function for receiving
packets. Hence netif_rx is changed to netif_receive_skb.
Furthermore netif_napi_del should be used in the probe and remove function
to clean up the NAPI resource information.
Thanks to Francois Romieu, David Shwatrz and Rami Rosen for their help on
this patch.

It'd be nicer with spaces around the &

It'd be slightly faster code moving the ipv6_hdr(skb)
assignment below these tests.

I think that it probably would, although I expect that this would be the case
independent of the implementations (virtual station interfaces vs. macvlans).
The only other option I see is to disallow those features that can't be done in
hardware, but I think thats unworkable long term.

From: Avinash kumar @ 2013-09-22 16:09 UTC (permalink / raw)
To: sbhatewara; +Cc: pv-drivers, netdev, linux-kernel, Avinash kumar
replaced msleep(1) by usleep_range(1000,1500). Documentation/timers/timers_howto.txt
suggests use of usleep_range() in place of msleep() where desired delay is of range
1-20 ms.

The would be the ideal situation. Netback pushes large packets to
netfront and netfront sees large packets.

However Anirban saw the case when backend interface receives large
packets but netfront sees MTU size packets, so my thought is there is
certain configuration that leads to this issue. As we cannot tell
users what to enable and what not to enable so I would like to solve
this within our driver.

AIUI if the packet that frontend sees is large already then the GRO path
is quite short which will not introduce heavy penalty, while on the
other hand if packet is segmented doing GRO improves throughput.

On 848xx PHY (10G-baseT), half-duplex was always advertised regardless of the
actual configuration. Change the 848xx duplex settings to advertise half-duplex
only if configured.

Relocate bnx2x_disable_kr2 function, and use it to disable KR2 in case it is not
configured in order to clear it's configuration, otherwise the link may come up
at 20G instead of the requested 10G-KR. In addition, restart AN after
disabling KR2 as part of the KR2 work-around.

* [PATCH net 1/5] bnx2x: Generalize KR work-around
From: Yaniv Rosner @ 2013-09-22 11:59 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Eilon Greenstein, Yaniv Rosner
In-Reply-To: <1379851166-11959-1-git-send-email-yanivr@broadcom.com>
Previously, in case of KR link down, the driver would reset the PHY and restart
auto negotiation only when old Warpcore microcode was used (below D108).
This patch comes to generalize this by keep trying to restart KR link,
regardless of Warpcore microcode, since it was found that it solves another link
issue which source is a link-partner. As part of this change, the signal
detect is no longer a condition to apply the work-around to cover this new case.
Like before, as long as the link is down, AN will be restarted every 2 seconds.
