100GbE Intel Wired LAN Driver Updates 2018-10-03

This series contains updates to ice and virtchnl.

Yashaswini Raghuram adds a new virtchnl capability flag to support the
exchange of additional supported speeds.

Anirudh adds support for SR-IOV for the ice driver.  Added code to
initialize, configure and use mailbox queues for PF and VF
communication.  Updated the VSI and queue management to handle both PF
and VF VSI type.  Added "Adaptive Virtual Function (AVF)" support for
the ice PF driver by implementing virtchnl commands.  Extended the
malicious driver detection logic to include the VF driver as well.
Fixed the queue region size which needs to be log base 2 of the number
of queues in region.

Brett fixes an issue which was causing switch rules to be lost, by
making a call to ice_update_pkt_fwd_rule() with the necessary changes.
Fixed how the PF and VF assigned the ITR index by adding a struct member
itr_idx to be used to dynamically program the correct ITR index.

Dave fixed a potential NULL pointer dereference by adding checks in the
filter handling.

This issue came about when looking at the VF function
ice_vc_cfg_irq_map_msg. Currently we are assigning the itr_setting value
to the itr_idx received from the AVF driver, which is not correct and is
not used for the VF flow anyway. Currently the only way we set the ITR
index for both the PF and VF driver is by hard coding ICE_TX_ITR or
ICE_RX_ITR for the ITR index on each q_vector.

To fix this, add the member itr_idx in struct ice_ring_container. This
can then be used to dynamically program the correct ITR index. This change
also affected the PF driver so make the necessary changes there as well.

Also, removed the itr_setting member in struct ice_ring because it is not
being used meaningfully and is going to be removed in a future patch that
includes dynamic ITR.

On another note, this will be useful moving forward if we decide to split
Rx/Tx rings on different q_vectors instead of sharing them as queue pairs.

virtchnl is a protocol/interface specification that allows the Intel
"Adaptive Virtual Function (AVF)" driver (iavf.ko) to work with more than
one physical function driver. The AVF driver sends "virtchnl commands"
(control plane only) to the PF driver over mailbox queues and the PF driver
executes these commands and returns a result to the VF, again over mailbox.

This patch adds AVF support for the ice PF driver by implementing the
following virtchnl commands:

VIRTCHNL_OP_VERSION
VIRTCHNL_OP_GET_VF_RESOURCES
VIRTCHNL_OP_RESET_VF
VIRTCHNL_OP_ADD_ETH_ADDR
VIRTCHNL_OP_DEL_ETH_ADDR

Post VF initialization, there are a couple of different ways in which a

Also introduced in this patch is a helper function ice_aq_send_msg_to_vf
to send messages to VF over the mailbox queue. The PF uses this to send

This patch implements parts of ice_sriov_configure and VF reset flow.

To create virtual functions (VFs), the user sets a value in num_vfs
through sysfs. This results in the kernel calling the handler for
.sriov_configure which is ice_sriov_configure.

VF setup first starts with a VF reset, followed by allocation of the VF
VSI using ice_vf_vsi_setup. Once the VF setup is complete a state bit
ICE_VF_STATE_INIT is set in the vf->states bitmap to indicate that
the VF is ready to go.

Also for VF reset to go into effect, it's necessary to issue a disable
queue command (ice_aqc_opc_dis_txqs). So this patch updates multiple
functions in the disable queue flow to take additional parameters that
distinguish if queues are being disabled due to VF reset.

Presently, for non-zero copy case, separate pages are allocated for
storing plaintext and encrypted text of records. These pages are stored
in sg_plaintext_data and sg_encrypted_data scatterlists inside record
structure. Further, sg_plaintext_data & sg_encrypted_data are passed
to cryptoapis for record encryption. Allocating separate pages for
plaintext and encrypted text is inefficient from both required memory
and performance point of view.

This patch adds support of inplace encryption of records. For non-zero
copy case, we reuse the pages from sg_encrypted_data scatterlist to
copy the application's plaintext data. For the movement of pages from
sg_encrypted_data to sg_plaintext_data scatterlists, we introduce a new
function move_to_plaintext_sg(). This function add pages into
sg_plaintext_data from sg_encrypted_data scatterlists.

tls_do_encryption() is modified to pass the same scatterlist as both
source and destination into aead_request_set_crypt() if inplace crypto
has been enabled. A new ariable 'inplace_crypto' has been introduced in
record structure to signify whether the same scatterlist can be used.
By default, the inplace_crypto is enabled in get_rec(). If zero-copy is
used (i.e. plaintext data is not copied), inplace_crypto is set to '0'.

Similar to other patches from ERic.

As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.

In netvsc driver it uses NAPI for TX completions. The default
poll_napi will do this for us now and avoid the capture.

dpaa2-eth: Add support for Rx flow classification

The Management Complex (MC) firmware initially allowed the
configuration of a single key to be used both for Rx flow hashing
and flow classification. This prevented us from supporting
Rx flow classification independently of the hash key configuration.

Newer firmware versions expose separate commands for
configuring the two types of keys, so we can use them to
introduce Rx classification support. For frames that don't match
any classification rule, we fall back to statistical distribution
based on the current hash key.

The first patch in this set updates the Rx hashing code to use
the new firmware API for key config. Subsequent patches introduce
the firmware API for configuring the classification and actual
support for adding and deleting rules via ethtool.

Add support for inserting and deleting Rx flow classification
rules through ethtool.

We support classification based on some header fields for

Rx queues are core affine, so the action argument effectively
selects on which cpu the matching frame will be processed.
Discarding the frame is also supported.

For firmware versions that support it, configure an Rx flow
classification key at probe time.

Hardware expects all rules in the classification table to share
the same key. So we setup a key containing all supported fields
at driver init and when a user adds classification rules through
ethtool, we will just mask out the unused header fields.

Since the key composition process is the same for flow
classification and hashing, reuse existing code where possible.
