allow user to offload tc action to net device
Baowen Zheng says:
Allow use of flow_indr_dev_register/flow_indr_dev_setup_offload to offload

The motivation for this work is to prepare for using TC police action
instances to provide hardware offload of OVS metering feature - which calls
for policers that may be used by multiple flows and whose lifecycle is
independent of any flows that use them.
This patch includes basic changes to offload drivers to return EOPNOTSUPP
if this feature is used - it is not yet supported by any driver.

The MPTCP packet scheduler has sub-optimal behavior with asymmetric
subflows: if the faster subflow-level cwin is closed, the packet
scheduler can enqueue "too much" data on a slower subflow.
When all the data on the faster subflow is acked, if the mptcp-level
cwin is closed, and link utilization becomes suboptimal.
The solution is implementing blest-like[1] HoL-blocking estimation,
transmitting only on the subflow with the shorter estimated time to
flush the queued memory. If such subflows cwin is closed, we wait
even if other subflows are available.
This is quite simpler than the original blest implementation, as we
leverage the pacing rate provided by the TCP socket. To get a more
accurate estimation for the subflow linger-time, we maintain a
per-subflow weighted average of such info.
Additionally drop magic numbers usage in favor of newly defined
macros and use more meaningful names for status variable.

The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability added support that allows
the VF to support 802.1Q and 802.1ad VLAN insertion and stripping if
successfully negotiated via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS.
Multiple changes were needed to support this new functionality.

insertion offload requests via virtchnl.
2. Added the new method iavf_set_vlan_offload_features() that's

set the aq_required bits based on the current VLAN offload
configuration of the VF's netdev.

The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability added support that allows
the PF to set the location of the Tx and Rx VLAN tag for insertion and
stripping offloads. In order to support this functionality a few changes
are needed.
1. Add a new method to cache the VLAN tag location based on negotiated
capabilities for the Tx and Rx ring flags. This needs to be called in
the initialization and reset paths.
2. Refactor the transmit hotpath to account for the new Tx ring flags.
When IAVF_TXR_FLAGS_VLAN_LOC_L2TAG2 is set, then the driver needs to
insert the VLAN tag in the L2TAG2 field of the transmit descriptor.
When the IAVF_TXRX_FLAGS_VLAN_LOC_L2TAG1 is set, then the driver needs
to use the l2tag1 field of the data descriptor (same behavior as
before).
3. Refactor the iavf_tx_prepare_vlan_flags() function to simplify
transmit hardware VLAN offload functionality by only depending on the
skb_vlan_tag_present() function. This can be done because the OS
won't request transmit offload for a VLAN unless the driver told the
OS it's supported and enabled.
4. Refactor the receive hotpath to account for the new Rx ring flags and
VLAN ethertypes. This requires checking the Rx ring flags and
descriptor status bits to determine the location of the VLAN tag.
Also, since only a single ethertype can be supported at a time, check
the enabled netdev features before specifying a VLAN ethertype in
__vlan_hwaccel_put_tag().

Based on VIRTCHNL_VF_OFFLOAD_VLAN_V2, the VF can now support more VLAN
capabilities (i.e. 802.1AD offloads and filtering). In order to
communicate these capabilities to the netdev layer, the VF needs to
parse its VLAN capabilities based on whether it was able to negotiation
VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2 or neither of
these.
In order to support this, add the following functionality:
iavf_get_netdev_vlan_hw_features() - This is used to determine the VLAN
features that the underlying hardware supports and that can be toggled
off/on based on the negotiated capabiltiies. For example, if
VIRTCHNL_VF_OFFLOAD_VLAN_V2 was negotiated, then any capability marked
with VIRTCHNL_VLAN_TOGGLE can be toggled on/off by the VF. If
VIRTCHNL_VF_OFFLOAD_VLAN was negotiated, then only VLAN insertion and/or
stripping can be toggled on/off.
iavf_get_netdev_vlan_features() - This is used to determine the VLAN
features that the underlying hardware supports and that should be
enabled by default. For example, if VIRTHCNL_VF_OFFLOAD_VLAN_V2 was
negotiated, then any supported capability that has its ethertype_init
filed set should be enabled by default. If VIRTCHNL_VF_OFFLOAD_VLAN was
negotiated, then filtering, stripping, and insertion should be enabled
by default.
Also, refactor iavf_fix_features() to take into account the new
capabilities. To do this, query all the supported features (enabled by
default and toggleable) and make sure the requested change is supported.
If VIRTCHNL_VF_OFFLOAD_VLAN_V2 is successfully negotiated, there is no
need to check VIRTCHNL_VLAN_TOGGLE here because the driver already told
the netdev layer which features can be toggled via netdev->hw_features
during iavf_process_config(), so only those features will be requested
to change.

In order to support the new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability the
VF driver needs to rework it's initialization state machine and reset
flow. This has to be done because successful negotiation of
VIRTCHNL_VF_OFFLOAD_VLAN_V2 requires the VF driver to perform a second
capability request via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS before
configuring the adapter and its netdev.
Add the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit when sending the
VIRTHCNL_OP_GET_VF_RESOURECES message. The underlying PF will either
support VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2 or
neither. Both of these offloads should never be supported together.
Based on this, add 2 new states to the initialization state machine:
__IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS
__IAVF_INIT_CONFIG_ADAPTER
The __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state is used to request/store
the new VLAN capabilities if and only if VIRTCHNL_VLAN_OFFLOAD_VLAN_V2
was successfully negotiated in the __IAVF_INIT_GET_RESOURCES state.
The __IAVF_INIT_CONFIG_ADAPTER state is used to configure the
adapter/netdev after the resource requests have finished. The VF will
move into this state regardless of whether it successfully negotiated
VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2.
Also, add a the new flag IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS and set
it during VF reset. If VIRTCHNL_VF_OFFLOAD_VLAN_V2 was successfully
negotiated then the VF will request its VLAN capabilities via
VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS during the reset. This is needed
because the PF may change/modify the VF's configuration during VF reset
(i.e. modifying the VF's port VLAN configuration).
This also, required the VF to call netdev_update_features() since its
VLAN features may change during VF reset. Make sure to call this under
rtnl_lock().

Currently VIRTCHNL only allows for VLAN filtering and offloads to happen
on a single 802.1Q VLAN. Add support to filter and offload on inner,
outer, and/or inner + outer VLANs.
This is done by introducing the new capability
VIRTCHNL_VF_OFFLOAD_VLAN_V2. The flow to negotiate this new capability
is shown below.
1. VF - sets the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit in the
virtchnl_vf_resource.vf_caps_flags during the
VIRTCHNL_OP_GET_VF_RESOURCES request message. The VF should also set
the VIRTCHNL_VF_OFFLOAD_VLAN bit in case the PF driver doesn't support
the new capability.
2. PF - sets the VLAN capability bit it supports in the
VIRTCHNL_OP_GET_VF_RESOURCES response message. This will either be
VIRTCHNL_VF_OFFLOAD_VLAN_V2, VIRTCHNL_VF_OFFLOAD_VLAN, or none.
3. VF - If the VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability was ACK'd by the
PF, then the VF needs to request the VLAN capabilities of the
PF/Device by issuing a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS request.
If the VIRTCHNL_VF_OFFLOAD_VLAN capability was ACK'd then the VF
knows only single 802.1Q VLAN filtering/offloads are supported. If no
VLAN capability is ACK'd then the PF/Device doesn't support hardware
VLAN filtering/offloads for this VF.
4. PF - Populates the virtchnl_vlan_caps structure based on what it
allows/supports for that VF and sends that response via
VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS.
After VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS is successfully negotiated
the VF driver needs to interpret the capabilities supported by the
underlying PF/Device. The VF will be allowed to filter/offload the
inner 802.1Q, outer (various ethertype), inner 802.1Q + outer
(various ethertypes), or none based on which fields are set.
The VF will also need to interpret where the VLAN tag should be inserted
and/or stripped based on the negotiated capabilities.

RX fencing allows the driver to know that any prior change to the RQs has
finished, e.g. when the RQs are disabled/enabled or the hashkey/indirection
table are changed, RX fencing is required.
Remove the previous workaround "ssleep(1)" and add the real support for
RX fencing as the PF driver supports the MANA_FENCE_RQ request now (any
old PF driver not supporting the request won't be used in production).
