* tipc: Partition name table instance array info into two partsAllan Stephens2011-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modifies the name table array structure that contains the name sequence instances for a given name type so that the publication lists associated with a given instance are stored in a dynamically allocated structure, rather than being embedded within the array entry itself. This change is being done for several reasons: 1) It reduces the amount of data that needs to be copied whenever a given array is expanded or contracted to accommodate the first publication of a new name sequence or the removal of the last publication of an existing name sequence. 2) It reduces the amount of memory associated with array entries that are currently unused. 3) It facilitates the upcoming conversion of the publication lists from TIPC-specific circular lists to standard kernel lists. (Standard lists cannot be used with the former array structure because the relocation of array entries during array expansion and contraction would corrupt the lists.) Note that, aside from introducing a small amount of code to dynamically allocate and free the structure that now holds publication list info, this change is largely a simple renaming exercise that replaces references to "sseq->LIST" with "sseq->info->LIST" (or "info->LIST").

* tipc: Optimizations & corrections to message rejectionAllan Stephens2011-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Optimizes the creation of a returned payload message by duplicating the original message and then updating the small number of fields that need to be adjusted, rather than building the new message header from scratch. In addition, certain operations that are not always required are relocated so that they are only done if needed. These optimizations also have the effect of addressing other issues that were present previously: 1) Fixes a bug that caused the socket send routines to return the size of the returned message, rather than the size of the sent message, when a returnable payload message was sent to a non-existent destination port. 2) The message header of the returned message now matches that of the original message more closely. The header is now always the same size as the original header, and some message header fields that weren't being initialized in the returned message header are now populated correctly -- namely the "d" and "s" bits, and the upper bound of a multicast name instance (where present).

* net: remove mm.h inclusion from netdevice.hAlexey Dobriyan2011-06-21
| | | | | | | | | | | | | | | | | Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file.

Also if an APP entry in use is deleted the stack/driver may want to choose from the existing APP entries.

| | | | | | | | | | | | | | | | This adds a setapp routine for IEEE802.1Qaz encoded APP data types. The IEEE 802.1Qaz spec encodes the priority bits differently and allows for multiple APP data entries of the same selector and protocol. Trying to force these to use the same set routines was becoming tedious. Furthermore, userspace could probably enforce the correct semantics, but expecting drivers to do this seems error prone in the firmware case. For these reasons add ieee_dcb_setapp() that understands the IEEE 802.1Qaz encoded form. Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

* net: dcbnl, add multicast group for DCBJohn Fastabend2011-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that dcbnl is being used in many cases by more than a single agent it is beneficial to be notified when some entity either driver or user space has changed the DCB attributes. Today applications either end up polling the interface or relying on a user space database to maintain the DCB state and post events. Polling is a poor solution for obvious reasons. And relying on a user space database has its own downside. Namely it has created strange boot dependencies requiring the database be populated before any applications dependent on DCB attributes starts or the application goes into a polling loop. Populating the database requires negotiating link setting with the peer and can take anywhere from less than a second up to a few seconds depending on the switch implementation. Perhaps more importantly if another application or an embedded agent sets a DCB link attribute the database has no way of knowing other than polling the kernel. This prevents applications from responding quickly to changes in link events which at least in the FCoE case and probably any other protocols expecting a lossless link may result in IO errors. By adding a multicast group for DCB we have clean way to disseminate kernel DCB link attributes up to user space. Avoiding the need for user space to maintain a coherant database and disperse events that potentially do not reflect the current link state.

* ixgbe: setup redirection table for multiple packet buffersJohn Fastabend2011-06-21
| | | | | | | | | | | | | Setup RSS redirection table to be compatible with multiple packet buffers.
