Now that we've rolled the virtual channel API version to 1.1, add some macros to test what version is being used by our partner in crime. For the VF, add some macros to determine what our device capabilities are. Change-ID: I79f6683d4c23bd76a8ad9fd492776fcc1208e1dc Signed-off-by:

To prepare for the changes coming up in the X722 device and future devices, the virtual channel interface has to change slightly. The VF driver can now report what its capable of supporting, which then informs the PF driver when it sends the configuration information back to the VF. A 1.1 VF driver on a 1.0 PF driver should not send its capabilities. Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect or depend upon receiving the VF capabilities. All other aspects of the API are unchanged. Change-ID: I530cc55f107edd1ee8bdf95830aa90b87854058a Signed-off-by:

This patch changes the switch statement for dynamic interrupt throttling and adds a default case. With this patch, we check the latency setting instead of the current ITR settings and the included refactor improves performance. Without this patch, the ITR setting would never change dynamically, and there was no default. Change-ID: Idb5a8a14c7109ec47c90f6e94bd43baa17d7ee37 Signed-off-by:

This patch extends the reporting of the RSS key and hash table by adding support for X550 VFs. The difference is that X550 VFs have their own registers for RSS key and indirection table, so there is no need to query the PF. The RSS key and indirection table are stored in the adapter structure during the configuration of VFRSSRK and VFRETA which in turn can be used in ethtool for reporting. The logic for writing VFRETA is also changed to make sure that the indirection table is reported correctly. In addition this patch adds defines for the VFRETA entries and number of VFRSSRK registers as well as some whitespace cleanups. Reported-by:

Yuval Mintz says: ==================== bnx2x: update FW, rebrand and more This patch series does several things - it updates the bnx2x FW into 7.12.30 which both contains some small fixes as well as opening the door for several new features for the device - mainly vxlan/geneve offloads and vlan filtering offload. It then adds a new Multi-function mode [BD] which requires this FW in order to operate. In addition, this finally rebrands the driver from a 'broadcom' driver into a 'qlogic' driver [although it would still reside under Broadcom's tree in the kernel]. ==================== Signed-off-by: -

Devices with up-to-date management FW will be able to store register dumps on their persistent storage - in case management FW identifies a fatal error it would gather and store such dumps, which could later be retrieved using specific debug tools. This patch adds the necessary part in the driver in order to make the feature operational, as well as update users [under debug] during load in case their device contains a dump of a previous crash.

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following: - Packets from a VF with pvid configured which were sent with a different vlan were transmitted instead of being discarded. - FCoE traffic might not recover after a failue while there's traffic to another function. In addition, this FW opens the door for the driver to implement several new features; Specifically, this enhances the device's support for encapsulated packets and will allow vxlan/geneve offloads to be added in the future, as well as vlan filtering offload.

The driver is written as if it can adapt to a low memory situation allocating less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In reality though the driver would malfunction in this case. Stop being overly smart and just fail in such situation -- this is achieved by moving the memory allocation from ravb_ring_format() to ravb_ring_init(). We leave dma_map_single() calls in place but make their failure non-fatal by marking the corresponding RX descriptors with zero data size which should prevent DMA to an invalid addresses.

Some architectures like POWER can have a NUMA node_possible_map that contains sparse entries. This causes memory corruption with openvswitch since it allocates flow_cache with a multiple of num_possible_nodes() and assumes the node variable returned by for_each_node will index into flow->stats[node]. Use nr_node_ids to allocate a maximal sparse array instead of num_possible_nodes(). The crash was noticed after 3af229f2 was applied as it changed the node_possible_map to match node_online_map on boot. Fixes: 3af229f2Signed-off-by:

Edward Cree says: ==================== sfc: support for cascaded multicast filtering Recent versions of firmware for SFC9100 adapters add support for filter chaining, in which packets matching multiple filters are delivered to all filters' recipients, rather than only the highest match-priority filter as was previously the case. This patch series enables this feature and redesigns the filter handling code to make use of it; in particular, subscribing to a multicast address on one function no longer prevents traffic to that address reaching another function which is in promiscuous or allmulti mode. If the firmware does not support filter chaining, the driver will fall back to the old behaviour. ==================== Signed-off-by: -

If the workaround to support cascaded multicast filters ("workaround_26807") is enabled, the broadcast filter and individual multicast filters are not inserted when in promiscuous or allmulti mode. There is a race while inserting and removing filters when entering and leaving promiscuous mode. When changing promiscuous state with cascaded multicast filters, the old multicast filters are removed before inserting the new filters to avoid duplicating packets; this can lead to dropped packets until all filters have been inserted. The efx_nic:mc_promisc flag is added to record the presence of a multicast promiscuous filter; this gives a simple way to tell if the promiscuous state is changing. Signed-off-by: -

If a function is in promiscuous mode and another function has a broadcast or multicast filter inserted, the function in promiscuous mode won't see that broadcast or multicast traffic. Most notably this breaks broadcast, which means ARP doesn't work. Less show-stoppingly, a function listening on a multicast address that's also in promiscuous mode will not see that multicast traffic if another function is also listening on that multicast address.

When enabling the workaround for cascaded multicast filters, the MC can reset other functions if they have already inserted filters. In that case, the workaround has been enabled, but print an info message in the log recording that other functions had to be reset. As other functions were reset, the MC will have incremented its boot count, so also increment the warm_boot_count on the function which enabled the workaround, as that function won't have received an MC reboot event and does not need to reset.
