The Flow Director function ice_fdir_create_dflt_rules() calls few
times function ice_create_init_fdir_rule() each time with different
enum ice_fltr_ptype parameter. Next step is to return error code if
error occurred.
Change the code to store all necessary default rules in constant array
and call ice_create_init_fdir_rule() in the loop. It makes it easy to
extend the list of default rules in the future, without the need of
duplicate code more and more.

Fix Flow Director not allowing to re-map traffic to 0th queue when action
is configured to drop (and vice versa).
The current implementation of ethtool callback in the ice driver forbids
change Flow Director action from 0 to -1 and from -1 to 0 with an error,
e.g:
# ethtool -U eth2 flow-type tcp4 src-ip 1.1.1.1 loc 1 action 0
# ethtool -U eth2 flow-type tcp4 src-ip 1.1.1.1 loc 1 action -1
rmgr: Cannot insert RX class rule: Invalid argument
We set the value of `u16 q_index = 0` at the beginning of the function
ice_set_fdir_input_set(). In case of "drop traffic" action (which is
equal to -1 in ethtool) we store the 0 value. Later, when want to change
traffic rule to redirect to queue with index 0 it returns an error
caused by duplicate found.
Fix this behaviour by change of the type of field `q_index` from u16 to s16
in `struct ice_fdir_fltr`. This allows to store -1 in the field in case
of "drop traffic" action. What is more, change the variable type in the
function ice_set_fdir_input_set() and assign at the beginning the new
`#define ICE_FDIR_NO_QUEUE_IDX` which is -1. Later, if the action is set
to another value (point specific queue index) the variable value is
overwritten in the function.

While the iavf driver adds a s/w limit (128) on the number of FDIR
filters that the VF can request, a malicious VF driver can request more
than that and exhaust the resources for other VFs.
Add a similar limit in ice.

Add support for 'flow-type ether' Flow Director rules via ethtool.
Create packet segment info for filter configuration based on ethtool
command parameters. Reuse infrastructure already created for
ipv4 and ipv6 flows to convert packet segment into
extraction sequence, which is later used to program the filter
inside Flow Director block of the Rx pipeline.
Rules not containing masks are processed by the Flow Director,
and support the following set of input parameters in all combinations:
src, dst, proto, vlan-etype, vlan, action.
It is possible to specify address mask in ethtool parameters but only
00:00:00:00:00 and FF:FF:FF:FF:FF are valid.
The same applies to proto, vlan-etype and vlan masks:
only 0x0000 and 0xffff masks are valid.
Testing:
(DUT) iperf3 -s
(DUT) ethtool -U ens785f0np0 flow-type ether dst <ens785f0np0 mac> \
action 10
(DUT) watch 'ethtool -S ens785f0np0 | grep rx_queue'
(LP) iperf3 -c ${DUT_IP}
Counters increase only for:
'rx_queue_10_packets'
'rx_queue_10_bytes'

Allow the user to set the symmetric Toeplitz hash function via:
# ethtool -X eth0 hfunc toeplitz symmetric-xor
All existing RSS configurations will be converted to symmetric unless they
have a non-symmetric field (other than IP src/dst and L4 src/dst ports)
used for hashing. The driver will reject a new RSS configuration if such
a field is requested.
The hash function in the E800 NICs is set per-VSI and a specific AQ
command is needed to modify the hash function. Use the AQ command to
enable setting the symmetric Toeplitz RSS hash function for any VSI
in the new ice_set_rss_hfunc().
When the Symmetric Toeplitz hash function is used, the hardware sets the
input set of the RSS (Toeplitz) algorithm to be the XOR of the fields
index by HSYMM and the fields index by the INSET registers. We use this
to create a symmetric hash by setting the HSYMM registers to point to
their counterparts in the INSET registers:
HSYMM [src_fv] = dst_fv;
HSYMM [dst_fv] = src_fv;
where src_fv and dst_fv are the indexes of the protocol's src and dst
fields.

The flow director and RSS blocks use separate methods to generate a
unique 64 bit ID for the flow. This is not extendable, especially for
the RSS that already uses all 64 bit space.
Refactor the flow generation API so that the ID is generated within
ice_flow_add_prof(). The FD and RSS blocks caches the generated ID for

The virtual channel is going to be extended to support FDIR and
RSS configure from AVF. New data structures and OP codes will be
added, the patch enable the FDIR part.
To support above advanced AVF feature, we need to figure out
what kind of data structure should be passed from VF to PF to describe
an FDIR rule or RSS config rule. The common part of the requirement is
we need a data structure to represent the input set selection of a rule's
hash key.
An input set selection is a group of fields be selected from one or more
network protocol layers that could be identified as a specific flow.
For example, select dst IP address from an IPv4 header combined with
dst port from the TCP header as the input set for an IPv4/TCP flow.
The patch adds a new data structure virtchnl_proto_hdrs to abstract
a network protocol headers group which is composed of layers of network
protocol header(virtchnl_proto_hdr).
A protocol header contains a 32 bits mask (field_selector) to describe
which fields are selected as input sets, as well as a header type
(enum virtchnl_proto_hdr_type). Each bit is mapped to a field in
enum virtchnl_proto_hdr_field guided by its header type.
+------------+-----------+------------------------------+
| | Proto Hdr | Header Type A |
| | +------------------------------+
| | | BIT 31 | ... | BIT 1 | BIT 0 |
| |-----------+------------------------------+
|Proto Hdrs | Proto Hdr | Header Type B |
| | +------------------------------+
| | | BIT 31 | ... | BIT 1 | BIT 0 |
| |-----------+------------------------------+
| | Proto Hdr | Header Type C |
| | +------------------------------+
| | | BIT 31 | ... | BIT 1 | BIT 0 |
| |-----------+------------------------------+
| | .... |
+-------------------------------------------------------+
All fields in enum virtchnl_proto_hdr_fields are grouped with header type
and the value of the first field of a header type is always 32 aligned.
enum proto_hdr_type {
header_type_A = 0;
header_type_B = 1;
....
}
enum proto_hdr_field {
/* header type A */
header_A_field_0 = 0,
header_A_field_1 = 1,
header_A_field_2 = 2,
header_A_field_3 = 3,
/* header type B */
header_B_field_0 = 32, // = header_type_B << 5
header_B_field_0 = 33,
header_B_field_0 = 34
header_B_field_0 = 35,
....
};
So we have:
proto_hdr_type = proto_hdr_field / 32
bit offset = proto_hdr_field % 32
To simply the protocol header's operations, couple help macros are added.
For example, to select src IP and dst port as input set for an IPv4/UDP
flow.
we have:
struct virtchnl_proto_hdr hdr[2];
VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[0], IPV4)
VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[0], IPV4, SRC)
VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[1], UDP)
VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[1], UDP, DST)
The byte array is used to store the protocol header of a training package.
The byte array must be network order.
The patch added virtual channel support for iAVF FDIR add/validate/delete
filter. iAVF FDIR is Flow Director for Intel Adaptive Virtual Function
which can direct Ethernet packets to the queues of the Network Interface
Card. Add/delete command is adding or deleting one rule for each virtual
channel message, while validate command is just verifying if this rule
is valid without any other operations.
To add or delete one rule, driver needs to config TCAM and Profile,
build training packets which contains the input set value, and send
the training packets through FDIR Tx queue. In addition, driver needs to
manage the software context to avoid adding duplicated rules, deleting
non-existent rule, input set conflicts and other invalid cases.
NOTE:
Supported pattern/actions and their parse functions are not be included in
this patch, they will be added in a separate one.

Enable accelerated Receive Flow Steering (aRFS). It is used to steer Rx
flows to a specific queue. This functionality is triggered by the network
stack through ndo_rx_flow_steer and requires Flow Director (ntuple on) to
function.
The fltr_info is used to add/remove/update flow rules in the HW, the
fltr_state is used to determine what to do with the filter with respect
to HW and/or SW, and the flow_id is used in co-ordination with the
network stack.
The work for aRFS is split into two paths: the ndo_rx_flow_steer
operation and the ice_service_task. The former is where the kernel hands
us an Rx SKB among other items to setup aRFS and the latter is where
the driver adds/updates/removes filter rules from HW and updates filter
state.
In the Rx path the following things can happen:
1. New aRFS entries are added to the hash table and the state is
set to ICE_ARFS_INACTIVE so the filter can be updated in HW
by the ice_service_task path.
2. aRFS entries have their Rx Queue updated if we receive a
pre-existing flow_id and the filter state is ICE_ARFS_ACTIVE.
The state is set to ICE_ARFS_INACTIVE so the filter can be
updated in HW by the ice_service_task path.
3. aRFS entries marked as ICE_ARFS_TODEL are deleted
In the ice_service_task path the following things can happen:
1. New aRFS entries marked as ICE_ARFS_INACTIVE are added or
updated in HW.
and their state is updated to ICE_ARFS_ACTIVE.
2. aRFS entries are deleted from HW and their state is updated
to ICE_ARFS_TODEL.
