2019-05-26net: dynamically allocate fqdir structuresEric Dumazet

Michal Kalderon says: ==================== qed*: Improve performance on 100G link for offload protocols This patch series modifies the current implementation of PF selection. The refactoring of the llh code enables setting additional filters (mac / protocol) per PF, and improves performance for offload protocols (RoCE, iWARP, iSCSI, fcoe) on 100G link (was capped at 90G per single PF). Improved performance on 100G link is achieved by configuring engine affinty to each PF. The engine affinity is read from the Management FW and hw is configured accordingly. A new hw resource called PPFID is exposed and an API is introduced to utilize it. This additional resource enables setting the affinity of a PF and providing more classification rules per PF. qedr,qedi,qedf are also modified as part of the series. Without the changes functionality is broken. v1 --> v2 --------- - Remove iWARP module parameter. Instead use devlink param infrastructure for setting the iwarp_cmt mode.

This patch refactors the current llh implementation. It exposes a hw resource called ppfid (port-pfid) and implements an API for configuring the resource. Default configuration which was used until now limited the number of filters per PF and did not support engine affinity per protocol.

Maxime Chevallier says: ==================== net: mvpp2: Classifier updates, RSS Here is a set of updates for the PPv2 classifier, the main feature being the support for steering to RSS contexts, to leverage all the available RSS tables in the controller. The first two patches are non-critical fixes for the classifier, the first one prevents us from allocating too much room to store the classification rules, the second one configuring the C2 engine as suggested by the PPv2 functionnal specs. Patches 3 to 5 introduce support for RSS contexts in mvpp2, allowing us to steer traffic to dedicated RSS tables. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-05-25net: mvpp2: cls: Support steering to RSS contextsMaxime Chevallier
When steering to an RXQ, we can perform an extra RSS step to assign a queue from an RSS table. This is done by setting the RSS_EN attribute in the C2 engine. In that case, the RXQ that is assigned is the global RSS context id, that is then translated to an RSS table using the RXQ2RSS table. An example using ethtool to steer to RXQ 2 and 3 would be : ethtool -X eth0 weight 0 0 1 1 context new (This would print the allocated context id, let's say it's 1) ethtool -N eth0 flow-type udp4 dst-port 1234 context 1 loc 0 The hash parameters are the ones that are globally configured for RSS : ethtool -N eth0 rx-flow-hash udp4 sdfn When an RSS context is removed while there are active classification rules using this context, these rules are removed.

2019-05-25net: mvpp2: cls: Extract the RSS context when parsing the ethtool ruleMaxime Chevallier
ethtool_rx_flow_rule_create takes into parameter the ethtool flow spec, which doesn't contain the rss context id. We therefore need to extract it ourself before parsing the ethtool rule. The FLOW_RSS flag is only set in info->fs.flow_type, and not info->flow_type. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-05-25net: mvpp2: cls: Use RSS contexts to handle RSS tablesMaxime Chevallier
The PPv2 controller has 8 RSS tables that are shared across all ports on a given PPv2 instance. The previous implementation allocated one table per port, leaving others unused. By using RSS contexts, we can make use of multiple RSS tables per port, one being the default table (always id 0), the other ones being used as destinations for flow steering, in the same way as rx rings. This commit introduces RSS contexts management in the PPv2 driver. We always reserve one table per port, allocated when the port is probed. The global table list is stored in the struct mvpp2, as it's a global resource. Each port then maintains a list of indices in that global table, that way each port can have it's own numbering scheme starting from 0. One limitation that seems unavoidable is that the hashing parameters are shared across all RSS contexts for a given port. Hashing parameters for ctx 0 will be applied to all contexts.

2019-05-25flow_offload: use struct_size() in kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

This way more tests can easily be added in the future and can be run in virtually any MAC/GMAC/QoS/XGMAC platform. Having this we can find regressions and missing features in the driver while at the same time we can check if the IP is correctly working. We have been using this for some time now and I do have more tests to submit in the feature. My experience is that although writing the tests adds more development time, the gain results are obvious.

2019-05-24net: stmmac: Introduce selftests supportJose Abreu
We add support for selftests on stmmac driver with 9 basic sanity checks for now: - MAC Loopback - PHY Loopback - MMC Counters - EEE - Hash Filter Multicast - Perfect Filter Unicast - Multicast Filter All - Unicast Filter All - Flow Control This allows for fast tracking of regressions in the driver and helps in spotting mis-configuration of HW. Changes from v1: - Fix build error as module (David) - Check for link status before running tests Changes from RFC v2: - Return proper error code in stmmac_test_mmc (Corentin) - Use only 1 MMC counter in stmmac_test_mmc (Alexandre) Changes from RFC v1: - Change test_loopback to test_mac_loopback (Andrew) - Change timeout to retries (Andrew) - Add MC/UC filter tests (Andrew) - Only test in offline mode (Andrew) - Do not call phy_loopback twice (Alexandre) Signed-off-by: Jose Abreu <joabreu@synopsys.com> Cc: Joao Pinto <jpinto@synopsys.com> Cc: David S.

2019-05-24net: stmmac: dwxgmac2: Also pass control frames while in promisc modeJose Abreu
In order for the selftests to run the Flow Control selftest we need to also pass pause frames to the stack. Pass this type of frames while in promiscuous mode.
