* net: UDP tunnel encapsulation module for tunnelling different protocols like ↵Martin Varghese2020-02-243-0/+757
| | | | | | | | | | | | MPLS, IP, NSH etc. The Bareudp tunnel module provides a generic L3 encapsulation tunnelling module for tunnelling different protocols like MPLS, IP,NSH etc inside a UDP tunnel.

* ptp: Add a ptp clock driver for IDT 82P33 SMU.Min Li2020-02-244-0/+1192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IDT 82P33 Synchronization Management Unit (SMU) family provides tools to manage timing references, clock sources and timing paths for IEEE 1588 / Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE) based clocks. The device supports up to three independent timing paths that control: PTP clock synthesis; SyncE clock generation; and general purpose frequency translation. The device supports physical layer timing with Digital PLLs (DPLLs) and it supports packet based timing with Digitally Controlled Oscillators (DCOs). This patch adds support for ptp clock based on the device. Changes since v1: - As suggested by Richard Cochran: 1. Replace _mask_bit_count with the existing hweight8 2. Prefix all functions with idt82p33 3. Fix white space issues in Kconfig and Makefile 4. Remove forward declaration 5. Use adjfine instead of adjfreq for better resolution - As suggested by David Miller: 1. Replace CHAN_INIT macro with a static function idt82p33_channel_init 2. Employ reverse christmas tree ordering for local variables 3. Fix indentation problem by appropriate number of TAB then SPACE character Signed-off-by: Min Li <min.li.xe@renesas.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* mlxsw: spectrum_trap: Add ACL devlink-trap supportJiri Pirko2020-02-242-0/+18
| | | | | | | | | | | | | Add the trap group used to report ACL drops. Setup the trap IDs for ingress/egress flow action drop. Register the two packet traps associated with ACL trap group with devlink during driver initialization. As these are "source traps", set the disabled trap group to be the dummy, discarding as many packets in HW as possible.

* mlxsw: spectrum_trap: Introduce dummy group with thin policerJiri Pirko2020-02-242-0/+25
| | | | | | | | | | | | | For "source traps" it is not possible to change HPKT action to discard. But there is still need to disallow packets arriving to CPU as much as possible. Handle this by introduction of a "dummy group". It has a "thin" policer, which passes as less packets to CPU as possible. The rest is going to be discarded there. The "dummy group" is to be used later on by ACL trap (which is a "source trap").

Let both groups be the same for MLXSW_RXL however extend MLXSW_RXL_DIS to register separate groups for enable and disable.

* mlxsw: core: Allow to enable/disable rx_listener for trapJiri Pirko2020-02-242-10/+40
| | | | | | | | | | | | For source traps, the "thin policer" is going to be used in order to reduce the amount of trapped packets to minimum. However, there will be still small number of packets coming in that need to be dropped in the driver. Allow to enable/disable rx_listener related to specific trap in order to prevent unwanted packets to go up the stack.

| | | | | | | | | | | | Introduce a new set of traps: DISCARD_INGRESS_ACL and DISCARD_EGRESS_ACL Set the trap_action from NOP to TRAP which causes the packets dropped by the TRAP action to be trapped under new trap IDs, depending on the ingress/egress binding point.
