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.

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.

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: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NDavid 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: NJohn Fastabend <john.r.fastabend@intel.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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: NJohn Fastabend <john.r.fastabend@intel.com> Signed-off-by: NDavid 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.

The number of TX and RX queues allocated depends on the device type, the current features set, online CPUs, and various compile flags. To enable DCB with multiple queues and allow it to coexist with all the features currently implemented it has to setup a valid queue count. This is done at init time using the FDIR and RSS max queue counts and allowing each TC to allocate a queue per CPU. DCB will now use available queues up to (8 x TCs) this is somewhat arbitrary cap but allows DCB to use up to 64 queues. Its easy to increase this later if that is needed. This is prep work to enable Flow Director with DCB. After this DCB can easily coexist with existing features and no longer needs its own DCB feature ring.
