Subject: [PATCH 1/6] sctp: Add ADD/DEL ASCONF handling at the receiver.
This patch fixes the problem that the original code cannot delete
the remote address where the corresponding transport is currently
directed, even when the ASCONF is sent from the other address (this
situation happens when the single-homed sender transmits ASCONF
with ADD and DEL.)

Subject: [PATCH 3/6] sctp: Add Auto-ASCONF support (core).
SCTP reconfigure the IP addresses in the association by using
ASCONF chunks as mentioned in RFC5061. For example, we can
start to use the newly configured IP address in the existing
association. This patch implements automatic ASCONF operation
in the SCTP stack with address events in the host computer,
which is called auto_asconf.

This patch allows the application to operate Auto-ASCONF on/off
behavior via setsockopt() and getsockopt().

Subject: [PATCH 6/6] sctp: sctp: Add ASCONF operation on the single-homed host
In this case, the SCTP association transmits an ASCONF packet
including addition of the new IP address and deletion of the old
address. This patch implements this functionality.
In this case, the ASCONF chunk is added to the beginning of the
queue, because the other chunks cannot be transmitted in this state.

This tells the NIC to take the speed specified by ethtool into account
when configuring it instead of keeping the previous speed.

Initial driver reports different speeds depending on the port being
used. This patch advertises the speed to be 10Mbps in any case, which
is what it actually is on the wire.

* [PATCHv3 2/7] ethtool: Call ethtool's get/set_settings callbacks with cleaned data
From: David Decotigny @ 2011-04-28 1:27 UTC (permalink / raw)
To: David S. Miller, Ben Hutchings, mirq-linux, Stanislaw Gruszka,
Alexander Duyck <alexander.h.duyc
Cc: David Decotigny
In-Reply-To: <1303954043-17440-1-git-send-email-decot@google.com>
This makes sure that when a driver calls the ethtool's
get/set_settings() callback of another driver, the data passed to it
is clean. This guarantees that speed_hi will be zeroed correctly if
the called callback doesn't explicitely set it: we are sure we don't
get a corrupted speed from the underlying driver. We also take care of
setting the cmd field appropriately (ETHTOOL_GSET/SSET).
This applies to dev_ethtool_get_settings(), which now makes sure it
sets up that ethtool command parameter correctly before passing it to
drivers. This also means that whoever calls dev_ethtool_get_settings()
does not have to clean the ethtool command parameter. This function
also becomes an exported symbol instead of an inline.
All drivers visible to make allyesconfig under x86_64 have been
updated.

* [PATCHv3 4/7] ethtool: cosmetic: Use ethtool ethtool_cmd_speed API
From: David Decotigny @ 2011-04-28 1:27 UTC (permalink / raw)
To: David S. Miller, Ben Hutchings, mirq-linux, Stanislaw Gruszka,
Alexander Duyck <alexander.h.duyc
Cc: David Decotigny
In-Reply-To: <1303954043-17440-1-git-send-email-decot@google.com>
This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtoo_cmd_speed() instead.
For most drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.
All the drivers compiled with make allyesconfig ion x86_64 have been
updated.
Tested: make allyesconfig on x86_64 + e1000e/bnx2x work

* [PATCHv3 1/7] ethtool: cosmetics: enforce const-ness in ethtool_cmd_speed

The 'ep' argument of ethtool_cmd_speed is not altered: advertise it in
protoype. +Indentation fix. Also add comments to advise using the
ethtool_cmd_speed API to get/set the link speed.

* [PATCHv3 7/7] net/igb/e1000/e1000e: more robust ethtool duplex/speed configuration
From: David Decotigny @ 2011-04-28 1:27 UTC (permalink / raw)

In-Reply-To: <1303954043-17440-1-git-send-email-decot@google.com>
This makes sure that one cannot request a 99Mbps full-duplex and
get a 100Mbps half-duplex configuration in return due to the way the
speed/duplex parameters are handled internally. Credits to Ben Hutchings
for spotting this.
Tested: e1000 works

* [PATCHv3 0/7] ethtool: generalize use of ethtool_cmd_speed API
From: David Decotigny @ 2011-04-28 1:27 UTC (permalink / raw)
To: David S. Miller, Ben Hutchings, mirq-linux, Stanislaw Gruszka,

Hi,
Third version of the patch series ensuring ethtool_cmd::speed/_hi
fields are accessed using ethtool_cmd_speed/_set API. Thanks to Ben
and Stephen for their feedbacks that have been integrated here,
including some from Ben suggested in PATCHv1 and added here (intel GbE
drivers: last patch in the series).
Regards,
David Decotigny (7):
ethtool: cosmetics: enforce const-ness in ethtool_cmd_speed
ethtool: Call ethtool's get/set_settings callbacks with cleaned data
ethtool: Use the full 32 bit speed range in ethtool's set_settings
ethtool: cosmetic: Use ethtool ethtool_cmd_speed API
acenic: Fix using the specified speed when configuring NIC
tulip/de2104x: don't report different speeds depending on port type
net/igb/e1000/e1000e: more robust ethtool duplex/speed configuration

* [PATCHv3 3/7] ethtool: Use the full 32 bit speed range in ethtool's set_settings
From: David Decotigny @ 2011-04-28 1:27 UTC (permalink / raw)
To: David S. Miller, Ben Hutchings, mirq-linux, Stanislaw Gruszka,
Alexander Duyck <alexander.h.duyc
Cc: David Decotigny
In-Reply-To: <1303954043-17440-1-git-send-email-decot@google.com>
This makes sure the ethtool's set_settings() callback of network
drivers don't ignore the 16 most significant bits when ethtool calls
their set_settings().
All drivers compiled with make allyesconfig on x86_64 have been
updated.
Tested: make allyesconfig compiles + e1000e and bnx2x work

Subject: [PATCH 0/6 v8] sctp: Auto-ASCONF patch series
Series of 6 patches to support auto_asconf and the other related functionalities that auto_asconf relies on
Michio Honda (5):
sctp: Add ADD/DEL ASCONF handling at the receiver.
sctp: Add Auto-ASCONF support (core).
sctp: Add sysctl support for Auto-ASCONF.
sctp: Add socket option operation for Auto-ASCONF.
sctp: Add ASCONF operation on the single-homed host
YOSHIFUJI Hideaki (1):
sctp: Allow regular C expression in 4th argument for
SCTP_DEBUG_PRINTK_IPADDR macro.

Subject: [PATCH 1/6 v8] sctp: Add ADD/DEL ASCONF handling at the receiver.
This patch fixes the problem that the original code cannot delete
the remote address where the corresponding transport is currently
directed, even when the ASCONF is sent from the other address (this
situation happens when the single-homed sender transmits ASCONF
with ADD and DEL.)

Subject: [PATCH 3/6 v8] sctp: Add Auto-ASCONF support (core).
SCTP reconfigure the IP addresses in the association by using
ASCONF chunks as mentioned in RFC5061. For example, we can
start to use the newly configured IP address in the existing
association. This patch implements automatic ASCONF operation
in the SCTP stack with address events in the host computer,
which is called auto_asconf.

* [PATCH 6/6 v8] sctp: Add ASCONF operation on the single-homed host
From: Michio Honda @ 2011-04-28 2:01 UTC (permalink / raw)
To: netdev; +Cc: Honda Michio, YOSHIFUJI Hideaki, Wei Yongjun
>From 983b3d3f2ffe0173f0e63af029610ce301ff397c Mon Sep 17 00:00:00 2001
From: Michio Honda <micchie@sfc.wide.ad.jp>
Date: Tue, 26 Apr 2011 20:19:36 +0900
Subject: [PATCH 6/6 v8] sctp: Add ASCONF operation on the single-homed host
In this case, the SCTP association transmits an ASCONF packet
including addition of the new IP address and deletion of the old
address. This patch implements this functionality.
In this case, the ASCONF chunk is added to the beginning of the
queue, because the other chunks cannot be transmitted in this state.
