Add TC-MATCHALL classifier offload with TC-POLICE action applied for
all outgoing traffic on the underlying interface. Split flow block
offload to support both egress and ingress classification.
For example, to rate limit all outgoing traffic to 1 Gbps:
$ tc qdisc add dev enp2s0f4 clsact
$ tc filter add dev enp2s0f4 egress matchall skip_sw \
action police rate 1Gbit burst 8Kbit
Note that skip_sw is important. Otherwise, both stack and hardware
will end up doing policing. Policing can't be shared across flow
blocks. Only 1 egress matchall rule can be active at a time on the
underlying interface.
v5:
- No change.
v4:
- Removed check to reject police offload if prio is not 1.
- Moved TC_SETUP_BLOCK code to separate function.
v3:
- Added check to reject police offload if prio is not 1.
- Assign block_shared variable only for TC_SETUP_BLOCK.
v2:
- Added check to reject flow block sharing for policers.

The driver allocates the spinlock but not initialize it.

Once every napi poll cycle, check if numa node is different than
the page pool's numa id, and update it using page_pool_update_nid().
Alternatively, we could have registered an irq affinity change handler,
but page_pool_update_nid() must be called from napi context anyways, so
the handler won't actually help.
Performance testing:
XDP drop/tx rate and TCP single/multi stream, on mlx5 driver
while migrating rx ring irq from close to far numa:
mlx5 internal page cache was locally disabled to get pure page pool
results.
CPU: Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz
NIC: Mellanox Technologies MT27700 Family [ConnectX-4] (100G)
XDP Drop/TX single core:
NUMA | XDP | Before | After
---------------------------------------
Close | Drop | 11 Mpps | 10.9 Mpps
Far | Drop | 4.4 Mpps | 5.8 Mpps
Close | TX | 6.5 Mpps | 6.5 Mpps
Far | TX | 3.5 Mpps | 4 Mpps
Improvement is about 30% drop packet rate, 15% tx packet rate for numa
far test.
No degradation for numa close tests.
TCP single/multi cpu/stream:
NUMA | #cpu | Before | After
--------------------------------------
Close | 1 | 18 Gbps | 18 Gbps
Far | 1 | 15 Gbps | 18 Gbps
Close | 12 | 80 Gbps | 80 Gbps
Far | 12 | 68 Gbps | 80 Gbps
In all test cases we see improvement for the far numa case, and no
impact on the close numa case.

The valid memory address check in dma_capable only makes sense when mapping
normal memory, not when using dma_map_resource to map a device resource.
Add a new boolean argument to dma_capable to exclude that check for the
dma_map_resource case.

CPSW switchdev based driver which is operating in dual-emac mode by
default, thus working as 2 individual network interfaces. The Switch mode
can be enabled by configuring devlink driver parameter "switch_mode" to 1:
devlink dev param set platform/48484000.switch \
name switch_mode value 1 cmode runtime
This can be done regardless of the state of Port's netdevs - UP/DOWN, but
Port's netdev devices have to be UP before joining the bridge to avoid
overwriting of bridge configuration as CPSW switch driver completely
reloads its configuration when first Port changes its state to UP.
When the both interfaces joined the bridge - CPSW switch driver will start
marking packets with offload_fwd_mark flag unless "ale_bypass=0".
All configuration is implemented via switchdev API and notifiers.
Supported:
- SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS
- SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS: BR_MCAST_FLOOD
- SWITCHDEV_ATTR_ID_PORT_STP_STATE
- SWITCHDEV_OBJ_ID_PORT_VLAN
- SWITCHDEV_OBJ_ID_PORT_MDB
- SWITCHDEV_OBJ_ID_HOST_MDB
Hence CPSW switchdev driver supports:
- FDB offloading
- MDB offloading
- VLAN filtering and offloading
- STP

Part 1:
Introduce basic CPSW dual_mac driver (cpsw_new.c) which is operating in
dual-emac mode by default, thus working as 2 individual network interfaces.
Main differences from legacy CPSW driver are:
- optimized promiscuous mode: The P0_UNI_FLOOD (both ports) is enabled in
addition to ALLMULTI (current port) instead of ALE_BYPASS. So, Ports in
promiscuous mode will keep possibility of mcast and vlan filtering, which
is provides significant benefits when ports are joined to the same bridge,
but without enabling "switch" mode, or to different bridges.
- learning disabled on ports as it make not too much sense for
segregated ports - no forwarding in HW.
- enabled basic support for devlink.
devlink dev show
platform/48484000.switch
devlink dev param show
platform/48484000.switch:
name ale_bypass type driver-specific
values:
cmode runtime value false
- "ale_bypass" devlink driver parameter allows to enable
ALE_CONTROL(4).BYPASS mode for debug purposes.
- updated DT bindings.

A following patches introduce new CPSW switchdev driver which uses common
code with legacy CPSW driver. This will introduce build dependency between
CPSW switchdev and CPSW legacy drivers related to for_each_slave() and
cpsw_slave_index() - they can be compiled both, but only one of them will
be not functional depending in Kconfig settings due to duffrences in Slave
Ports indexes calculation.
To fix this make for_each_slave() local (it's used now only by legacy CPSW
driver) and convert cpsw_slave_index() to be a function pointer which is
assigned in probe. Driver to probe is defined by DT.

This driver currently requires platform data to specify the
operational mode and regulator init data (in case of regulator
mode).
Optionally specify the operational mode by looking at the name
of the devicetree child node.
Example: put chip in regulator mode:
i2c0 {
tps61052@33 {
compatible = "ti,tps61052";
reg = <0x33>;
regulator {
regulator-min-microvolt = <5000000>;

regulator-always-on;

Commit a753bfcfdb1f ("intel_th: Make the switch allocate its subdevices")
factored out intel_th_subdevice_alloc() from intel_th_populate(), but got
the error path wrong, resulting in two instances of a double put_device()
on a freshly initialized, but not 'added' device.
Fix this by only doing one put_device() in the error path.

Now, since driver became OF independent, no need to keep OF dependency.
