Each MDB entry is encoded in a nested netlink attribute called 'MDBA_MDB_ENTRY'. In turn, this attribute contains another nested attributed called 'MDBA_MDB_ENTRY_INFO', which encodes a single port group entry within the MDB entry. The cited commit added the ability to restart a dump from a specific port group entry. However, on failure to add a port group entry to the dump the entire MDB entry (stored in 'nest2') is removed, resulting in missing port group entries. Fix this by finalizing the MDB entry with the partial list of already encoded port group entries.

Oleksij Rempel says: ==================== ag71xx: add ethtool and flow control support The main target of this patches is to provide flow control support for ag71xx driver. To be able to validate this functionality, I also added ethtool support with HW counters.

This adds functionality to report driver stats to Hypervisor. (Users may want to turn this feature off as a matter of privacy so a "report-stats" flag is added as an ethtool priv option. It is also disabled by default.) The hypervisor would trigger a stats report in case "too many" packets dropped; the stats would be useful in debugging stuck queues. A "stats_report_trigger_cnt" stat is added to count the number of times the hypervisor attempts to trigger stats report. A timer is also added so that when report-stats is enabled, stat are updated once every 20 seconds. Reviewed-by:

Karsten Graul says: ==================== net/smc: updates 2020-09-10 Please apply the following patch series for smc to netdev's net-next tree. This patch series is a mix of various improvements and cleanups. The patches 1 and 10 improve the handling of large parallel workloads. Patch 8 corrects a kernel config default for config CCWGROUP on s390. Patch 9 allows userspace tools to retrieve socket information for more sockets. ==================== Signed-off-by: -

There are 6 types of workers which exist per smc connection. 3 of them are used for listen and handshake processing, another 2 are used for close and abort processing and 1 is the tx worker that moves calls to sleeping functions into a worker. To prevent flooding of the system work queue when many connections are opened or closed at the same time (some pattern uperf implements), move those workers to one of 3 smc-specific work queues. Two work queues are module-global and used for handshake and close workers. The third work queue is defined per link group and used by the tx workers that may sleep waiting for resources of this link group. And in smc_llc_enqueue() queue the llc_event_work work to the system prio work queue because its critical that this work is started fast. Reviewed-by:

smc_lgr_cleanup_early() schedules the free worker with delay. DMB unregistering occurs in this delayed worker increasing the risk to reach the SMCD SBA limit without need. Terminate the linkgroup immediately, since termination means early DMB unregistering. For SMCD the global smc_server_lgr_pending lock is given up early. A linkgroup to be given up with smc_lgr_cleanup_early() may already contain more than one connection. Using __smc_lgr_terminate() in smc_lgr_cleanup_early() covers this. And consolidate smc_ism_put_vlan() and smc_put_device() into smc_lgr_free() only. Signed-off-by:
