This change fixes the fact that we would trigger a null pointer dereference or specify the wrong ring if the rings were restored. This change makes certain that the DROP queue is a static value, and all other rings are based on the ring offsets for the PF.

This code adds support for displaying the filters that were added via the nfc interface. This is primarily to test the interface for now, but I am also looking into the feasibility of moving all of the ntuple filter code in ixgbe over to the nfc interface since it seems to be better implemented.

I am removing the requirement that Ntuple filters have the same number of queues and requirements as ATR. As a result this change will make it so that all the Ntuple flag does is disable ATR for now. This change fixes an issue in which we were incorrectly re-enabling ATR when we exited perfect filter mode. This was due to the fact that the logic assumed RSS and DCB were mutually exclusive which is no longer the case. To correct this we just need to add a check to guarantee DCB is disabled before re-enabling ATR.

Due to numerous issues in ntuple filters it has been decided to move the interface over to the network flow classification interface.

This adds support for a configuring the minimum number of links that must be active before asserting carrier. It is similar to the Cisco EtherChannel min-links feature. This allows setting the minimum number of member ports that must be up (link-up state) before marking the bond device as up (carrier on). This is useful for situations where higher level services such as clustering want to ensure a minimum number of low bandwidth links are active before switchover.

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. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

With multiple APP entries per selector and protocol drivers or stacks may want to pick a specific value or stripe traffic across many priorities. Also if an APP entry in use is deleted the stack/driver may want to choose from the existing APP entries. To facilitate this and avoid having duplicate code to walk the APP ring provide a routine dcb_ieee_getapp_mask() to return a u8 bitmask of all priorities set for the specified selector and protocol. This routine and bitmask is a helper for DCB kernel users. Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Now that we allow multiple IEEE App entries we need a way to remove specific entries. To do this add the ieee_dcb_delapp() routine.

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.

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.

This patch adds 2 tracepoints to get a status of a socket receive queue and related parameter. One tracepoint is added to sock_queue_rcv_skb. It records rcvbuf size and its usage. The other tracepoint is added to __sk_mem_schedule and it records limitations of memory for sockets and current usage. By using these tracepoints we're able to know detailed reason why kernel drop the packet.

It was suggested by "make versioncheck" that the follwing includes of linux/version.h are redundant: /home/jj/src/linux-2.6/net/caif/caif_dev.c: 14 linux/version.h not needed. /home/jj/src/linux-2.6/net/caif/chnl_net.c: 10 linux/version.h not needed. /home/jj/src/linux-2.6/net/ipv4/gre.c: 19 linux/version.h not needed. /home/jj/src/linux-2.6/net/netfilter/ipset/ip_set_core.c: 20 linux/version.h not needed. /home/jj/src/linux-2.6/net/netfilter/xt_set.c: 16 linux/version.h not needed. and it seems that it is right. Beyond manually inspecting the source files I also did a few build tests with various configs to confirm that including the header in those files is indeed not needed.
