| | | | | | | | | | Slaves represent typical network interfaces available from userspace. Each ieee802154 device/transceiver may have several slaves and able to be associated with several networks at the same time. So this patch adds structure for slaves declaration.

* mac802154: basic ieee802.15.4 device structuresalex.bluesman.smirnov@gmail.com2012-05-161-0/+126
| | | | | | | | | | | | | | | | | | The IEEE 802.15.4 Working Group focuses on the standardization of the bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC. The MAC layer provides access control to a shared channel and reliable data delivery. The main functions performed by the MAC sublayer are: association and disassociation, security control, optional star network topology functions, such as beacon generation and Guaranteed Time Slots (GTSs) management, generation of ACK frames (if used), and, finally, application support for the two possible network topologies described in the standard. This is an initial commit which describes main data structures needed for ieee802.15.4 compatible devices representation in the MAC layer.

| | | | | | | | | | | | | | | | | | | | | | | | | | We are going to delete the Token ring support. This removes any special processing in the core networking for token ring, (aside from net/tr.c itself), leaving the drivers and remaining tokenring support present but inert.

If any resources were not properly cleaned up during the shutdown process, an Oops would result. Fix so that delete slave (only) resources during cleanup. Master resources are cleaned up during unload process, and need not separately be cleaned. Note that during cleanup, we need to split the resource-tracker freeing functionality. Before removing all the bitmaps, we free any leftover slave resources. However, we can only remove the resource tracker linked list after all bitmap frees, since some of the freeing functions (e.g., mlx4_cleanup_eq_table) use paravirtualized FW commands which expect the resource tracker linked list to be present.

* | net/mlx4_core: Do not reset module-parameter num_vfs when fail to enable sriovJack Morgenstein2012-05-161-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider the following scenario: 2 HCAs, where only one of which can run SRIOV. If we reset the module parameter, all the VFs of the SRIOV HCA will be claimed by the PPF host (-- the code relies on num_vfs being non-zero to avoid this claiming, and num_vfs was reset when pci_enable_sriov failed for the non-SRIOV HCA). The solution is not to touch the num_vfs parameter. Also, eliminate the unneeded check of num_vfs when disabling sriov (the dev flag bit is sufficient).

* | net/mlx4_core: Fix init_port mask state for slavesJack Morgenstein2012-05-161-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In function mlx4_INIT_PORT_wrapper, the port state mask for the slave is only set if we are invoking the INIT_PORT fw command. However, the reference count for the (initialized) port is incremented anyway. This creates a problem in that when we have multiple slaves, then the CLOSE_PORT command will never be invoked. The reason is that in the CLOSE_PORT wrapper, if the port-state mask is zero for the slave (which it is), the wrapper returns without doing anything. The only slave which will not return immediately in the CLOSE_PORT wrapper is that slave for which INIT_PORT was invoked. The fix is to not have the port-state mask setting depend on the logic for calling the INIT_PORT fw command.

| | | | | | | | | | | | | | | | | | | | __ratelimit() can be considered an inverted bool test because it returns true when not ratelimited. Several tests in the kernel tree use this __ratelimit() function incorrectly. No net_ratelimit uses are incorrect currently though. Most uses of net_ratelimit are to log something via printk or pr_<level>. In order to minimize the uses of net_ratelimit, and to start standardizing the code style used for __ratelimit() and net_ratelimit(), add a net_ratelimited_function() macro and net_<level>_ratelimited() logging macros similar to pr_<level>_ratelimited that use the global net_ratelimit instead of a static per call site "struct ratelimit_state".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of a client X roaming from a generic node A to another node B, it is possible that a third node C gets A's OGM but not B's. At this point in time, if C wants to send data to X it will send a unicast packet destined to A. The packet header will contain A's last ttvn (C got A's OGM and so it knows it). The packet will travel towards A without being intercepted because the ttvn contained in its header is the newest for A. Once A will receive the packet, A's state will not report to be in a "roaming phase" (because, after a roaming, once A sends out its OGM, all the changes are committed and the node is considered not to be in the roaming state anymore) and it will match the ttvn carried by the packet. Therefore there is no reason for A to try to alter the packet's route, thus dropping the packet because the destination client is not there anymore. However, C is well aware that it's routing information towards the client X is outdated as it received an OGM from A saying that the client roamed away. Thanks to this detail, this patch introduces a small change in behaviour: as long as C is in the state of not knowing the new location of client X it will forward the traffic to its last known location using ttvn-1 of the destination. By using an older ttvn node A will be forced to re-route the packet. Intermediate nodes are also allowed to update the packet's destination as long as they have the information about the client's new location. Signed-off-by: Antonio Quartulli <ordex@autistici.org>
