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:
