2020-05-06net: flow_offload: skip hw stats check for FLOW_ACTION_HW_STATS_DONT_CAREPablo Neira Ayuso
This patch adds FLOW_ACTION_HW_STATS_DONT_CARE which tells the driver that the frontend does not need counters, this hw stats type request never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests the driver to disable the stats, however, if the driver cannot disable counters, it bails out. TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_* except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED (this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*.

2020-05-06net: ethernet: ti: am65-cpsw-nuss: fix irqs typeGrygorii Strashko
The K3 INTA driver, which is source TX/RX IRQs for CPSW NUSS, defines IRQs triggering type as EDGE by default, but triggering type for CPSW NUSS TX/RX IRQs has to be LEVEL as the EDGE triggering type may cause unnecessary IRQs triggering and NAPI scheduling for empty queues. It was discovered with RT-kernel. Fix it by explicitly specifying CPSW NUSS TX/RX IRQ type as IRQF_TRIGGER_HIGH.

2020-05-06ionic: Use debugfs_create_bool() to export boolGeert Uytterhoeven
Currently bool ionic_cq.done_color is exported using debugfs_create_u8(), which requires a cast, preventing further compiler checks.

One may notice that automatically-learnt entries 'never' expire, even though the bridge configures the address age period at 300 seconds.

2020-05-06net: dsa: ocelot: the MAC table on Felix is twice as largeVladimir Oltean
When running 'bridge fdb dump' on Felix, sometimes learnt and static MAC addresses would appear, sometimes they wouldn't. Turns out, the MAC table has 4096 entries on VSC7514 (Ocelot) and 8192 entries on VSC9959 (Felix), so the existing code from the Ocelot common library only dumped half of Felix's MAC table. They are both organized as a 4-way set-associative TCAM, so we just need a single variable indicating the correct number of rows.

The CPTS module is used to facilitate host control of time sync operations.

Introduced driver provides Linux PTP hardware clock for each CPTS device and network packets timestamping where applicable. CPTS PTP hardware clock supports following operations: - Set time - Get time - Shift the clock by a given offset atomically - Adjust clock frequency - Time stamp external events - Periodic output signals Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.
