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.

Ido Schimmel says: ==================== mlxsw: Make driver more robust In recent months we fixed several bugs in the driver that could have been avoided by re-evaluating some of the involved code paths and by introducing relevant and comprehensive test cases. This patchset tries to do that by introducing a set of small and mostly non-functional changes in addition to a new test. I have further improvements in mind, but they can be done in a different set. Patch #1 makes sure we correctly sanitize upper devices of a VLAN interface. Patch #2 removes an unexpected behavior from the driver, in which routes configured on a VLAN interface will cease being offloaded after certain operations. Patch #3 is a small cleanup. Patch #4 simplifies the driver by removing reference counting from VLAN entries configured on a port. Patches #5-#6 simplify linking/unlinking from a bridge, especially when LAG and VLAN devices are involved. They make both operations symmetric even when ports are unlinked from a bridged LAG device. Patch #7-#9 make router interface (RIF) deletion more robust by removing reliance on device chain to indicate whether a NETDEV_DOWN event in the inet{,6}addr notification chains should be processed. This is due to the fact that IP addresses can be flushed from a netdev after it was unlinked from its lower device. Patch #10 adds a new test to for valid and invalid configurations over mlxsw ports. Some of the test cases are derived from recent fixes. I expect that more test cases will be added over time. ==================== Signed-off-by: -

Add a new test that is focused on rtnetlink configuration. Its purpose is to test valid and invalid (as deemed by mlxsw) configurations and make sure that they succeed / fail without producing a trace. Some of the test cases are derived from recent fixes in order to make sure that the fixed bugs are not introduced again. Signed-off-by:

Previous patches tried to make RIF deletion more robust and avoid use-after-free situations. As another precaution, hold a reference on a RIF's netdev and release it when the RIF is deleted. Signed-off-by:
-
Ido Schimmel authored
In the past we had multiple instances where RIFs were not properly deleted. One of the reasons for leaking a RIF was that at the time when IP addresses were flushed from the respective netdev (prompting the destruction of the RIF), the netdev was no longer a mlxsw upper. This caused the inet{,6}addr notification blocks to ignore the NETDEV_DOWN event and leak the RIF. Instead of checking whether the netdev is our upper when an IP address is removed, we can instead check if the netdev has a RIF configured. To look up a RIF we need to access mlxsw private data, so the patch stores the notification blocks inside a mlxsw struct. This then allows us to use container_of() and extract the required private data. Signed-off-by: -
Ido Schimmel authored
Next patch is going to make RIF deletion more robust by removing reliance on fragile mlxsw_sp_lower_get(). This is because a netdev is not necessarily our upper anymore when its IP addresses are flushed. The inet{,6}addr notification blocks are going to resolve 'struct mlxsw_sp' using container_of(), but the functions they call still use mlxsw_sp_lower_get(). As a preparation for the next patch, propagate 'struct mlxsw_sp' down to the functions called from the notification blocks and remove reliance on mlxsw_sp_lower_get(). Signed-off-by:
