2011-09-21macmace, macsonic: cleanupFinn Thain2-17/+1
We check ether_type before registering the platform device in arch/m68k/mac/config.c. Doing the same test again in the driver is redundant so remove it. Multiple probes should not happen since the conversion to platform devices, so lose that test too. Then macmace.c need not include macintosh.h, so remove that and irq.h and include linux/interrupt.h explicitly. Tested on PowerBook 520, Quadra 660av, LC 630.

2011-09-21net/smsc911x: Correctly configure 16-bit register access from DTDave Martin1-0/+2
The SMSC911X_USE_16BIT needs to be set when using 16-bit register access. However, currently no flag is set if the device tree doesn't specify 32-bit access, resulting in a BUG() and a non- working driver when 16-bit register access is configured for smsc911x in the DT. This patch should set the SMSC911X_USE_16BIT flag in a manner consistent with the documented DT bindings.

Many of the function names in the hot path are carrying an extra "_adv" suffix on the end of them to represent the fact that they are using advanced descriptors instead of legacy descriptors. However since all igb uses are advanced descriptors adding the extra suffix doesn't really add any additional data.

The previous patch should have updated the allocation so that the rings can be treated as read-only within the clean_rx_irq function.

2011-09-19igb: update ring and adapter structure to improve performanceAlexander Duyck2-41/+46
This change is meant to improve performance by splitting the Tx and Rx rings into 3 sections. The first is primarily a read only section containing basic things like the indexes, a pointer to the dev and netdev structures, and basic information. The second section contains the stats and next_to_use and next_to_clean values. The third section is primarily unused values that can just be placed at the end of the ring and are not used in the hot path. The adapter structure has several sections that are read in the hot path. In order to improve performance there I am combining the frequent read hot path items into a single cache line.

2011-09-17tipc: Ensure both nodes recognize loss of contact between themAllan Stephens4-18/+42
Enhances TIPC to ensure that a node that loses contact with a neighboring node does not allow contact to be re-established until it sees that its peer has also recognized the loss of contact. Previously, nodes that were connected by two or more links could encounter a situation in which node A would lose contact with node B on all of its links, purge its name table of names published by B, and then fail to repopulate those names once contact with B was restored. This would happen because B was able to re-establish one or more links so quickly that it never reached a point where it had no links to A -- meaning that B never saw a loss of contact with A, and consequently didn't re-publish its names to A. This problem is now prevented by enhancing the cleanup done by TIPC following a loss of contact with a neighboring node to ensure that node A ignores all messages sent by B until it receives a LINK_PROTOCOL message that indicates B has lost contact with A, thereby preventing the (re)establishment of links between the nodes. The loss of contact is recognized when a RESET or ACTIVATE message is received that has a "redundant link exists" field of 0, indicating that B's sending link endpoint is in a reset state and that B has no other working links. Additionally, TIPC now suppresses the sending of (most) link protocol messages to a neighboring node while it is cleaning up after an earlier loss of contact with that node. This stops the peer node from prematurely activating its link endpoint, which would prevent TIPC from later activating its own end. TIPC still allows outgoing RESET messages to occur during cleanup, to avoid problems if its own node recognizes the loss of contact first and tries to notify the peer of the situation. Finally, TIPC now recognizes an impending loss of contact with a peer node as soon as it receives a RESET message on a working link that is the peer's only link to the node, and ensures that the link protocol suppression mentioned above goes into effect right away -- that is, even before its own link endpoints have failed. This is necessary to ensure correct operation when there are redundant links between the nodes, since otherwise TIPC would send an ACTIVATE message upon receiving a RESET on its first link and only begin suppressing when a RESET on its second link was received, instead of initiating suppression with the first RESET message as it needs to. Note: The reworked cleanup code also eliminates a check that prevented a link endpoint's discovery object from responding to incoming messages while stale name table entries are being purged. This check is now unnecessary and would have slowed down re-establishment of communication between the nodes in some situations.

The location of an RX flow classification rule is needed to identify it for retrieval, replacement or deletion. However it also defines the priority of the rule in the case that a flow is matched by multiple rules. This is what I intended to imply by referring to the use of a TCAM, commonly used to implement that behaviour. However there are other ways this can be done, and it is better to specify this explicitly. Further, I want to add the option for automatic selection of rule locations.
