Jay Vosburgh 1b76b31693 Convert bonding timers to workqueues
Convert bonding timers to workqueues.  This converts the various
monitor functions to run in periodic work queues instead of timers.  This
patch introduces the framework and convers the calls, but does not resolve
various locking issues, and does not stand alone.

Mathieu Desnoyers 1c3f0b8e07 Change struct marker users
Prior to use struct marker in the linux kernel markers, we need to clean
two drivers which use this structure name.

Change bonding driver types :
- struct marker to struct bond_marker.
- marker_t to bond_marker_t.
- marker_header to bond_marker_header.
- marker_header_t to bond_marker_header_t.

Change qla4xxx struct marker_entry usage :
- Change struct marker_entry for struct qla4_marker_entry.

Eric W. Biederman e730c15519 [NET]: Make packet reception network namespace safe
This patch modifies every packet receive function
registered with dev_add_pack() to drop packets if they
are not from the initial network namespace.

This should ensure that the various network stacks do
not receive packets in a anything but the initial network
namespace until the code has been converted and is ready
for them.

Jay Vosburgh 031ae4deb0 bonding: Fix 802.3ad no carrier on "no partner found" instance
Modify carrier state determination for 802.3ad mode to comply
with section 43.3.9 of IEEE 802.3, which requires that "Links that are
not successful candidates for aggregation (e.g., links that are attached
to other devices that cannot perform aggregation or links that have been
manually configured to be non-aggregatable) are enabled to operate as
individual IEEE 802.3 links."

	Bug reported by Laurent Chavey <chavey@google.com>.  This patch
is an updated version of his patch that changes the wording of
commentary and adds an update to the driver version.

Arnaldo Carvalho de Melo 459a98ed88 [SK_BUFF]: Introduce skb_reset_mac_header(skb)
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can
later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.

Jay Vosburgh 89cc76f95a [PATCH] bonding: Don't mangle LACPDUs
Fixed handling of 802.3ad LACPDUs.  Do not byte swap data in
place in the packet.  Updated nomenclature of "__ntohs_lacpdu" to be
"htons"; it was previously used for both ntohs and htons operations, but
only called ntohs functions.

Jay Vosburgh 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.

David S. Miller f2ccd8fa06 [NET]: Kill skb->real_dev
Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.

It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.

Jay Vosburgh 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:

Linus Torvalds 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!
