If ice driver has q_vectors w/ active NAPI that has no rings, then this will result in a divide by zero error. To correct it I am updating the driver code so that we only support NAPI on q_vectors that have 1 or more rings allocated to them. See commit 13a8cd19 ("i40e: Do not enable NAPI on q_vectors that have no rings") for detail. Signed-off-by:

Out of bound read reported by KASan. i40iw_net_event() reads unconditionally 16 bytes from neigh->primary_key while the memory allocated for "neighbour" struct is evaluated in neigh_alloc() as tbl->entry_size + dev->neigh_priv_len where "dev" is a net_device. But the driver does not setup dev->neigh_priv_len and we read beyond the neigh entry allocated memory, so the patch in the next mail fixes this. Signed-off-by:

Section 4.5.9 of the datasheet says that the total size of all packet buffers combined (TxPB 0 + 1 + 2 + 3 + RxPB + BMC2OS + OS2BMC) must not exceed 60KB. Today we are configuring a total of 62KB, so reduce the RxPB from 32KB to 30KB in order to respect that. The choice of changing RxPBSIZE here is mainly because it seems more correct to give more priority to the transmit packet buffers over the receiver ones when running in Qav mode. Also, the BMC2OS and OS2BMC sizes are already too short. Signed-off-by:

This change is based off of the work and suggestion of Jan Jablonsky <jan.jablonsky@thalesgroup.com>. The Watchdog workqueue in igb driver is scheduled every 2s for each network interface. That includes updating a statistics protected by spinlock. Function igb_update_stats in this case will be protected against preemption. According to number of a statistics registers (cca 60), processing this function might cause additional cpu load on CPU0. In case of statistics spinlock may be replaced with mutex, which reduce latency on CPU0.

Michael Chan says: ==================== bnxt_en: Update for net-next. Three main changes in this series, besides the usual firmware spec update: 1. Add support for a new firmware communication channel direct to the firmware processor that handles flow offloads. This speeds up flow offload operations. 2. Use 64-bit internal flow handles to increase the number of flows that can be offloaded. 3. Add level-2 context memory paging so that we can configure more context memory for RDMA on the 57500 chips. Allocate more context memory if RDMA is enabled on the 57500 chips. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Older firmware only supports 16-bit flow handle, because of which the number of flows that can be offloaded can’t scale beyond a point. Newer firmware supports 64-bit flow handle enabling the host to scale upto millions of flows. With the new 64-bit flow handle support, driver has to query flow stats in a different way compared to the older approach. This patch adds support for 64-bit flow handle and new way to query flow stats. Signed-off-by:

To support level 2 context page memory structures, enhance the bnxt_ring_mem_info structure with a "depth" field to specify the page level and add a flag to specify using full pages for L1 and L2 page tables. This is needed to support RDMA functionality on 57500 chips since RDMA requires more context memory. Signed-off-by:

Earlier, some of the firmware commands (ex: CFA_FLOW_*) which are processed by KONG processor were sent to the CHIMP processor from the host. This approach was taken as there was no direct message channel to KONG. CHIMP in turn used to send them to KONG. Newer firmware supports a new message channel which the host can send messages directly to the KONG processor. This patch adds support for required changes needed in the driver to support direct KONG message channel. This speeds up flow related messages sent to the firmware for CLS_FLOWER offload.

While doing DOWN operation, the driver will reclaim the memory which has already used for TX. If the hardware is processing this memory, it will cause a RCB error to the hardware.

Each pf supports max 64 vectors and 128 tqps. For 2p/4p core scenario, there may be more than 64 cpus online. So the result of min_t(u16, num_Online_cpus(), tqp_num) may be more than 64.
