Brett Creeley acd1751a39 ice: Remove unnecessary wait when disabling/enabling Rx queues
In ice_vsi_ctrl_rx_rings() we are unnecessarily waiting for
QRX_CTRL_QENA_REQ and QRX_CTRL_QENA_STAT to be the same value prior to
disabling each Rx queue. There is no reason to do this so remove
this wait loop as we already have a wait loop after disabling/enabling
the Rx queue through the QRX_CTRL register to make sure it gets
successfully disabled/enabled.

Brett Creeley b9c8bb06b5 ice: Add ability to update rx-usecs-high
Currently the driver allows rx-usecs-high values to be set,
but when querying the device for rx-usecs-high the value
does not stick. This is because it was not yet implemented.
Add code to allow the user to change rx-usecs-high and
use this to set the q_vector's intrl value.

Maxime Chevallier bec2d46d14 net: mvpp2: cls: Allow dropping packets with classification offload
This commit introduces support for the "Drop" action in classification
offload. This corresponds to the "-1" action with ethtool -N.

This is achieved using the color marking actions available in the C2
engine, which associate a color to a packet. These colors can be either
Green, Yellow or Red, Red meaning that the packet should be dropped.

Green and Yellow colors are interpreted by the Policer, which isn't
supported yet.

This method of dropping using the Classifier is different than the
already existing early-drop features, such as VLAN filtering and MAC
UC/MC filtering, which are performed during the Parsing step, and
therefore take precedence over classification actions.

Maxime Chevallier 90b509b39a net: mvpp2: cls: Add Classification offload support
This commit introduces basic classification offloading support for the
PPv2 controller.

The PPv2 classifier has many classification engines, for now we only use
the C2 TCAM match engine.

This engine allows to perform ternary lookups on 64 bits keys (called
Header Extracted Key), that are built by extracting fields from the packet
header and concatenating them. At most 4 fields can be extracted for a
single lookup.

This basic implementation allows to build the HEK from the following
fields :
 - L4 source and destination ports (for UDP and TCP)

More fields are to be added in the future.

Classification flows are added through the ethtool interface, using the
newly introduced flow_rule infrastructure as an internal rule
representation, allowing to more easily implement tc flower rules if
need be.

The internal design for now allocates one range of 4 rules per port
due to the internal design of the flow table, which uses 22 sub-flows.

When inserting a classification rule, the rule is created in every
relevant sub-flow.

This low rule-count is a very simple design which reaches quickly the
limitations of the flow table ordering, but guarantees that the rule
ordering will always be respected.

This commit only introduces support for the "steer to rxq" action.

Maxime Chevallier 84e90b0b51 net: mvpp2: cls: Use a bitfield to represent the flow_type
As of today, the classification code is used only for RSS. We split the
incoming traffic into multiple flows, that correspond to the ethtool
flow_type parameter.

We don't want to use the ethtool flow definitions such as TCP_V4_FLOW,
for several reason :

 - We want to decorrelate the driver code from ethtool as much as
   possible, so that we can easily use other interfaces such as tc flower,

 - We want the flow_type to be a bitfield, so that we can match flows
   embedded into each other, such as TCP4 which is a subset of IP4.

This commit does the conversion to the newer type.

Esben Haabendal f14f5c11f0 net: ll_temac: Support indirect_mutex share within TEMAC IP
Indirect register access goes through a DCR bus bridge, which
allows only one outstanding transaction.  And to make matters
worse, each TEMAC IP block contains two Ethernet interfaces, and
although they seem to have separate registers for indirect access,
they actually share the registers.  Or to be more specific, MSW, LSW
and CTL registers are physically shared between Ethernet interfaces
in same TEMAC IP, with RDY register being (almost) specificic to
the Ethernet interface.  The 0x10000 bit in RDY reflects combined
bus ready state though.

So we need to take care to synchronize not only within a single
device, but also between devices in same TEMAC IP.

This commit allows to do that with legacy platform devices.

For OF devices, the xlnx,compound parent of the temac node should be
used to find siblings, and setup a shared indirect_mutex between them.
I will leave this work to somebody else, as I don't have hardware to
test that.  No regression is introduced by that, as before this commit
using two Ethernet interfaces in same TEMAC block is simply broken.

buffer descriptors (cmdac_bd) are handled as big-endian, independent of the

Note, when using app3 and app4 for piggybacking skb pointers there is no
need to care about endianness, as neither TEMAC nor SDMA access app3 and
app4 in TX buffer descriptors.

Finally, the order in remove function is corrected to be reverse order
of what is done in probe, i.e. calling temac_mdio_teardown() last, so we

Vladimir Oltean e74f014eb4 net: dsa: b53: Use vlan_filtering property from dsa_switch

dsa_port_is_vlan_filtering helper, fabricating a dsa_port pointer is a
bit awkward, so simply retrieve this from the dsa_switch structure.
