This patch initialize the RSS tables to evenly (depending on the packets RSS hashes) distribute the packets across port Rx queues. This helps to handle packets on different CPUs to improve performances, as more queues will be used in parallel. Signed-off-by:

The Rx FIFO size was set to the same value for all ports. This patch sets it depending on the maximum speed a given port can handle. This is only working for PPv2.2. Signed-off-by:

David Ahern says: ==================== net: Allow non-fatal messages to be passed in extack There are many cases where networking subsystems throw non-fatal warning messages that end up in dmesg / kernel log to which a user making the change is completely oblivious. This set makes the extack facility usable for returning such messages. The case in point here is spectrum and adding FIB rules which causes an offload abort. Make the use case more user friendly by letting the user know that offload is no longer happening because of the rule change. v2 - kept the offload abort in a work queue entry per Ido's comment ==================== Signed-off-by: -
David Ahern authored
Adding a FIB rule on a spectrum platform silently aborts FIB offload: $ ip ru add pref 99 from all to 192.168.1.1 table 10 $ dmesg -c [ 623.144736] mlxsw_spectrum 0000:03:00.0: FIB abort triggered. Note that FIB entries are no longer being offloaded to this device. This patch reworks FIB rule handling to return a message to the user: $ ip ru add pref 99 from all to 8.8.8.8 table 11 Error: spectrum: FIB rules not supported. Aborting offload. spectrum currently only checks whether the fib rule is a default rule or an l3mdev rule, both of which it knows how to handle. Any other it aborts FIB offload. Move the processing to check the rule type inline with the user request. If the rule is an unsupported one, then a work queue entry is used to abort the offload. Change the rule delete handling to just return since it does nothing at the moment. Signed-off-by:David Ahern <dsahern@gmail.com> Reviewed-by:

Vivien Didelot says: ==================== net: dsa: add port parsing functions This patchset adds port parsing functions called early in the new bindings parsing stage, which regroup all the fetching of static data available at the port level, including the port's type, name and CPU master interface. This simplifies the rest of the code which does not need to dig into device tree or platform data again in order to check a port's type or name. ==================== Signed-off-by: -

Fetching the master device can be done directly when a port is parsed from device tree or pdata, instead of waiting until dsa_dst_parse. Now that -EPROBE_DEFER is returned before we add the switch to the tree, there is no need to check for this error after dsa_dst_parse. Signed-off-by:

Assign a port's type at parsed time instead of waiting for the tree to be completed. Because this is now done earlier, we can use the port's type in dsa_port_is_* helpers instead of digging again in topology description. Signed-off-by:

Add symmetrical DSA port parsing functions for pdata and device tree, used to parse and validate a given port node or platform data. They don't do much for the moment but will be extended later on to assign a port type and get device references. Signed-off-by:

Vivien Didelot authored
There is no point into hiding the -EINVAL error code in ERR_PTR from a dsa_get_ports function, simply get the "ports" node directly from within the dsa_parse_ports_dn function. This also has the effect to make the pdata and device tree handling code symmetrical inside _dsa_register_switch. At the same time, rename dsa_parse_ports_dn to dsa_parse_ports_of because _of is a more common suffix for device tree parsing functions. Signed-off-by:

the verifier got progressively smarter over time and size of its internal state grew as well. Time to reduce the memory consumption. Before: sizeof(struct bpf_verifier_state) = 6520 After: sizeof(struct bpf_verifier_state) = 896 It's done by observing that majority of BPF programs use little to no stack whereas verifier kept all of 512 stack slots ready always. Instead dynamically reallocate struct verifier state when stack access is detected. Runtime difference before vs after is within a noise. The number of processed instructions stays the same.

Saeed Mahameed says: ==================== mlx5-updates-2017-10-31 mlx5e stats groups This series from Kamal introduces an important refactoring for mlx5e stats handling, which groups the stats into generic groups structure which allows to control the behavior and stats reporting per group in a modular way. In the first patch Kamal introduces a new data type "mlx5e_stats_grp" This change defines a new API to create a group of stats and simplifies the way of handling them. This struct will define the following behavior per group: - get_num_stats() - return the number of counters in the group. - fill_strings() - fill counters strings within the group. - fill_stats() - fill counters values within the group. All other patches will be straight forward refactoring per stats group, where Kamal will move each mlx5e stats group to use the new API. The idea is to have better flexibility and modularity to add new counters, all ethtool logic was rendered generic and loops through the generic stats groups and calls the groups callbacks to figure out how and what to report back to user space. Introducing new file en_stats.c to hold all the new stat groups logic and implementation. Static structures (counters descriptors) moved from en_stats.h to en_stats.c which reduces the mlx5_core binary footprint, originally reported and addressed by Stephen Hemminger: ("mlx5: fix space waste from ethtool descriptions") which was waived due to this re-design. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-10-31 This series contains updates to i40e, i40evf and net/sched. Arnd Bergmann cleans up the power management code to resolve a build warning. Shannon Nelson fixes i40e to only redistribute our vectors when we did not get the full count that we requested. Alex reverts a previous commit because it potentially causes a memory leak when combined with the current page recycling scheme. Amritha enables configuring cloud filters in i40e using the tc-flower classifier. The classification function of the filter is to match a packet to a traffic class. cls_flower is extended to offload classid to hardware. Hardware traffic classes are identified using classid values reserved in the range :ffe0 - :ffef. The cloud filters are added for a VSI and are cleaned up when the VSI is deleted. The filters that match on L4 ports needs enhanced admin queue functions with big buffer support for extended fields in cloud filter commands. ==================== Signed-off-by: -

Move the config customization into a site-local file tdc_config_local.py, so that updates of the tdc test software does not require hand-editing of the config. This patch includes a template for the site-local customization file. In addition, this makes it easy to revert to a stock tdc environment for testing the test framework and/or the core tests. Also it makes it harder for any custom config to be submitted back to the kernel tdc. Signed-off-by:

As part of documentation, supply some very simple test cases to illustrate how test cases work. One test case shows commands in the setup, command, verify and teardown stages. Other test cases show how to have a working test case that does not have commands in the setup, verify and/or teardown stages. Specifically, the command lists for setup and teardown can be empty. And the verify command must have a command, but it can be /bin/true. The regex must have a string, we recommend a single space, and the count of matches must be zero if you do not want to use the match feature of verify. Verify will always look for a return code of success (0) so we give /bin/true when we do not want to make a check there. Also, update the documentation for testcases to be more specific in the cases of: - accepting non-success return codes in setup and teardown stages - how to write the test when no setup, teardown and/or verify are desired. To run the example test cases: $ sudo -E ./tdc.py -f creating-testcases/example.json -l 1f: (example) simple test to test framework 2f: (example) simple test, no need for verify 3f: (example) simple test, no need for setup or teardown (or verify) $ sudo -E ./tdc.py -f creating-testcases/example.json Test 1f: simple test to test framework Test 2f: simple test, no need for verify Test 3f: simple test, no need for setup or teardown (or verify) All test results: 1..3 ok 1 1f simple test to test framework ok 2 2f simple test, no need for verify ok 3 3f simple test, no need for setup or teardown (or verify) $ Signed-off-by: -
