2007-12-07ibm_newemac: Skip EMACs that are marked unused by the firmwareHugh Blemings
Depending on how the 44x processors are wired, some EMAC cells might not be useable (and not connected to a PHY). However, some device-trees may choose to still expose them (since their registers are present in the MMIO space) but with an "unused" property in them.

2007-12-07ibm_newemac: Workaround reset timeout when no linkBenjamin Herrenschmidt
With some PHYs, when the link goes away, the EMAC reset fails due to the loss of the RX clock I believe. The old EMAC driver worked around that using some internal chip-specific clock force bits that are different on various 44x implementations. This is an attempt at doing it differently, by avoiding the reset when there is no link, but forcing loopback mode instead. It seems to work on my Taishan 440GX based board so far.

2007-12-07bonding: Add new layer2+3 hash for xor/802.3ad modesJay Vosburgh
Add new hash for balance-xor and 802.3ad modes. Originally submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by Jay Vosburgh to move setting of hash policy out of line, tweak the documentation update and add version update to 3.2.2. Glenn's original comment follows: Included is a patch for a new xmit_hash_policy for the bonding driver that selects slaves based on MAC and IP information. This is a middle ground between what currently exists in the layer2 only policy and the layer3+4 policy. This policy strives to be fully 802.3ad compliant by transmitting every packet of any particular flow over the same link. As documented the layer3+4 policy is not fully compliant for extreme cases such as ip fragmentation, so this policy is a nice compromise for environments that require full compliance but desire more than the layer2 only policy.

The three multivalue cases are different, because they also have to swallow back a trailing space.
