There is currently a single list that is containing both cluster-scope and zone-scope publications, and the list count is a separate free floating variable. Create a struct to bind the count to the list, and to pave the way for factoring out the publications into zone/cluster/node scope. The current "publ_root" most matches what will be the cluster scope list, so it is named accordingly in this commit.

The driver does not always use the same timing for what looks like the same operations. - DCR0 Use the same udelay everywhere for reset. Upper bound is 100 us. - DCR9 Use 5us delay for srom clock. 1us delay for phy_write_1bit (writes PHY_DATA_[01]) are not changed as they stay withing a 2,5MHz MDIO clock range.

This adds FDB bridge ops to the macvlan device passthru mode. Additionally a flags field was added and a NOPROMISC bit to allow users to use passthru mode without the driver calling dev_set_promiscuity(). The flags field is a u16 placed in a 4 byte hole (consuming 2 bytes) of the macvlan_dev struct. We want to do this so that the macvlan driver or stack above the macvlan driver does not have to process every packet. For the use case where we know all the MAC addresses of the endstations above us this works well. This patch is a result of Roopa Prabhu's work. Follow up patches are needed for VEPA and VEB macvlan modes. v2: Change from distinct nopromisc mode to a flags field to configure this. This avoids the tendency to add a new mode every time we need some slightly different behavior. v3: fix error in dev_set_promiscuity and add change and get link attributes for flags.

The UTA table was being set to the functional equivalent of promiscuous mode. This was resulting in traffic from the virtual function being flooded onto the wire and the PF device. This resulted in additional overhead for VF traffic sent to the network and in the case of traffic sent to the PF or another VF resulted in unwanted packets on the wire. This was actually not the intended behavior. Now that we can program the embedded switch correctly we can remove this snippit of code. Users who want to support this should configure the FDB correctly using the FDB ops.

It is useful to be able to monitor for FDB events in user space. This patch adds support to generate netlink events when a change is made to a device supporting the FDB ops.

This adds a dev_uc_add_excl() and dev_mc_add_excl() calls similar to the original dev_{uc|mc}_add() except it sets the global bit and returns -EEXIST for duplicat entires. This is useful for drivers that support SR-IOV, macvlan devices and any other devices that need to manage the unicast and multicast lists. v2: fix typo UNICAST should be MULTICAST in dev_mc_add_excl() CC: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

This adds two new flags NTF_MASTER and NTF_SELF that can now be used to specify where PF_BRIDGE netlink commands should be sent. NTF_MASTER sends the commands to the 'dev->master' device for parsing. Typically this will be the linux net/bridge, or open-vswitch devices. Also without any flags set the command will be handled by the master device as well so that current user space tools continue to work as expected. The NTF_SELF flag will push the PF_BRIDGE commands to the device. In the basic example below the commands are then parsed and programmed in the embedded bridge. Note if both NTF_SELF and NTF_MASTER bits are set then the command will be sent to both 'dev->master' and 'dev' this allows user space to easily keep the embedded bridge and software bridge in sync. There is a slight complication in the case with both flags set when an error occurs. To resolve this the rtnl handler clears the NTF_ flag in the netlink ack to indicate which sets completed successfully. The add/del handlers will abort as soon as any error occurs. To support this new net device ops were added to call into the device and the existing bridging code was refactored to use these. There should be no required changes in user space to support the current bridge behavior. A basic setup with a SR-IOV enabled NIC looks like this, veth0 veth2 | | ------------ | bridge0 | <---- software bridging ------------ / / ethx.y ethx VF PF \ \ <---- propagate FDB entries to HW \ \ -------------------- | Embedded Bridge | <---- hardware offloaded switching -------------------- In this case the embedded bridge must be managed to allow 'veth0' to communicate with 'ethx.y' correctly. At present drivers managing the embedded bridge either send frames onto the network which then get dropped by the switch OR the embedded bridge will flood these frames. With this patch we have a mechanism to manage the embedded bridge correctly from user space. This example is specific to SR-IOV but replacing the VF with another PF or dropping this into the DSA framework generates similar management issues. Examples session using the 'br'[1] tool to add, dump and then delete a mac address with a new "embedded" option and enabled ixgbe driver: # br fdb add 22:35:19:ac:60:59 dev eth3 # br fdb port mac addr flags veth0 22:35:19:ac:60:58 static veth0 9a:5f:81:f7:f6:ec local eth3 00:1b:21:55:23:59 local eth3 22:35:19:ac:60:59 static veth0 22:35:19:ac:60:57 static #br fdb add 22:35:19:ac:60:59 embedded dev eth3 #br fdb port mac addr flags veth0 22:35:19:ac:60:58 static veth0 9a:5f:81:f7:f6:ec local eth3 00:1b:21:55:23:59 local eth3 22:35:19:ac:60:59 static veth0 22:35:19:ac:60:57 static eth3 22:35:19:ac:60:59 local embedded #br fdb del 22:35:19:ac:60:59 embedded dev eth3 I added a couple lines to 'br' to set the flags correctly is all. It is my opinion that the merit of this patch is now embedded and SW bridges can both be modeled correctly in user space using very nearly the same message passing. [1] 'br' tool was published as an RFC here and will be renamed 'bridge' http://patchwork.ozlabs.org/patch/117664/ Thanks to Jamal Hadi Salim, Stephen Hemminger and Ben Hutchings for valuable feedback, suggestions, and review. v2: fixed api descriptions and error case with both NTF_SELF and NTF_MASTER set plus updated patch description.

To prevent interrupts lost they should be dropped only if they are scheduled via napi interfaces. In other case, there is exists situation when napi handler process TX interrupt, stay in RX processing and in that moment any other interrupt received. Then before this patch TX bit in ISR will be cleaned, napi schedule will not occur in case of currently processing event and TX interrupt definitely will be lost.
