ff59c4563a [PATCH] bonding: support carrier state for master
Add support for the bonding master to specify its carrier state
based upon the state of the slaves.  For 802.3ad, the bond is up if
there is an active, parterned aggregator.  For other modes, the bond is
up if any slaves are up.  Updates driver version to 3.0.3.

	Based on a patch by jamal <hadi@cyberus.ca>.

8f903c708f [PATCH] bonding: suppress duplicate packets
Originally submitted by Kenzo Iwami; his original description is:

The current bonding driver receives duplicate packets when broadcast/
multicast packets are sent by other devices or packets are flooded by the
switch. In this patch, new flags are added in priv_flags of net_device
structure to let the bonding driver discard duplicate packets in
dev.c:skb_bond().

	Modified by Jay Vosburgh to change a define name, update some
comments, rearrange the new skb_bond() for clarity, clear all bonding
priv_flags on slave release, and update the driver version.

5af47b2ff1 [PATCH] bonding: UPDATED hash-table corruption in bond_alb.c
I believe I see the race Michael refers to (tlb_choose_channel
may set head, which tlb_init_slave clears), although I was not able to
reproduce it.  I have updated his patch for the current netdev-2.6.git
tree and added a version update.  His original comment follows:

Our systems have been crashing during testing of PCI HotPlug
support in the various networking components.  We've faulted in
the bonding driver due to a bug in bond_alb.c:tlb_clear_slave()

In that routine, the last modification to the TLB hash table is
made without protection of the lock, allowing a race that can lead
tlb_choose_channel() to select an invalid table element.

b76cdba9cd [PATCH] bonding: add sysfs functionality to bonding (large)
This large patch adds sysfs functionality to the channel bonding module.
Bonds can be added, removed, and reconfigured at runtime without having
to reload the module.  Multiple bonds with different configurations are
easily configured, and ifenslave is no longer required to configure bonds.

8e3babcd69 [PATCH] bonding: fix feature consolidation
This should resolve http://bugzilla.kernel.org/show_bug.cgi?id=5519

The current feature computation loses bits that it doesn't know about,
resulting in an inability to add VLANs and possibly other havoc.
Rewrote function to preserve bits it doesn't know about, remove an
unneeded state variable, and simplify the code.

	This patch removes backwards compatibility for old ifenslave
binaries (ifenslave prior to verison 1.0.0).

	I did not similarly modify ifenslave itself; with sysfs on the
horizon, I don't see that as being worthwhile.

8531c5ffbc [PATCH] bonding: inherit zero-copy flags of slaves
This change allows a bonding device to inherit the "zero-copy"
features of its slave devices.

It was inspired by a couple of previous postings on this topic:
http://marc.theaimsgroup.com/?l=bonding-devel&m=111924607327794&w=2
http://marc.theaimsgroup.com/?l=bonding-devel&m=111925242706297&w=2
and it's largely a combination of the patches that appear in those
emails.

169a3e6663 bonding: xor/802.3ad improved slave hash
Add support for alternate slave selection algorithms to bonding
balance-xor and 802.3ad modes.  Default mode (what we have now: xor of
MAC addresses) is "layer2", new choice is "layer3+4", using IP and port
information for hashing to select peer.

Originally submitted by Jason Gabler for balance-xor mode;
modified by Jay Vosburgh to additionally support 802.3ad mode.  Jason's
original comment is as follows:

The attached patch to the Linux Etherchannel Bonding driver modifies the
driver's "balance-xor" mode as follows:

      - alternate hashing policy support for mode 2
        * Added kernel parameter "xmit_policy" to allow the specification
          of different hashing policies for mode 2.  The original mode 2
          policy is the default, now found in xmit_hash_policy_layer2().
        * Added xmit_hash_policy_layer34()

This patch was inspired by hashing policies implemented by Cisco,
Foundry and IBM, which are explained in
Foundry documentation found at:
http://www.foundrynet.com/services/documentation/sribcg/Trunking.html#112750

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
