fb7ad441d4 ethdev: replace callback getting filter operations
Since rte_flow is the only API for filtering operations,
the legacy driver interface filter_ctrl was too much complicated
for the simple task of getting the struct rte_flow_ops.

The filter type RTE_ETH_FILTER_GENERIC and
the filter operarion RTE_ETH_FILTER_GET are removed.
The new driver callback flow_ops_get replaces filter_ctrl.

ff7079a3a8 net/cxgbe: ignore flow default masks for unrequested fields
commit 536db938a4 ("net/cxgbe: add devargs to control filtermode and
filtermask") allows configuring hardware to select specific combination
of header fields to match in the incoming packets. However, the default
mask is set for all fields in the requested pattern items, even if the
field is not explicitly set in the combination and results in
validation errors. To prevent this, ignore setting the default masks
for the unrequested fields and the hardware will also ignore them in
validation, accordingly. Also, tweak the filter spec before finalizing
the masks.

24c1d49ac8 net/cxgbe: support flow API for matching all packets on VF
Add support to match all packets received on the underlying VF.

Use new firmware API to fetch the Virtual Interface Number (VIN)
allocated to each VF by the firmware. The VIN is required to
write filter rules to match all packets on VFs, whose identifier
is beyond max 7-bit value (i.e. 127) in VIID.

If firmware doesn't support fetching the VIN information, then
fallback to manually retrieving the VIN value from the 7-bit field
in the VIID, which only supports in range of 0..127. In this case,
packets belonging to VFs, whose identifier is beyond 127 can't be
matched.

Add support to match all packets received on the underlying PF

Note that the same 17-bit hardware tuple is shared between QinQ

Also, remove check to reject rules without spec because
RTE_FLOW_ITEM_TYPE_PF doesn't require a spec. Due to this check
removal, RTE_FLOW_ITEM_TYPE_PHY_PORT item needs to be updated to
handle NULL spec

Relax check for repeated pattern items for RTE_FLOW_ITEM_TYPE_VLAN
item, since the same item is used to represent both QinQ and VLAN

When QinQ match is enabled, the ethertype field in the hardware
spec must contain the innermost VLAN header's ethertype field,
and not the Ethernet header's ethertype field. The hardware
automatically searches for ethertype 0x88A8/0x8100 in Ethernet
header, when parsing incoming packet against QinQ/VLAN pattern,
respectively.

97e02581a1 net/cxgbe: fix races on flow API operations
When rules are being inserted from multiple cores, there are several
race conditions during rte_flow operations.

For example, when inserting rules from 2 cores simultaneously, both
the cores try to fetch a free available filter entry and they both
end up fetching the same entry. Both of them start overwriting the
same filter entry before sending to firmware, which results in wrong
rule being inserted to hardware.

Fix the races by adding spinlock to serialize the rte_flow operations.

9eb2c9a480 net/cxgbe: implement flow create operation
Define filter work request API used to construct filter operations
to be communicated with firmware. These requests are sent via
control queue and completions come asynchronously in firmware event
queue.

Implement flow create operation to create filters in LE-TCAM
(maskfull) region at specified index.

ee61f5113b net/cxgbe: parse and validate flows
Introduce rte_flow skeleton and implement validate operation.

Parse and convert <item>, <action>, <attributes> into hardware
specification. Perform validation, including basic sanity tests
and underlying device's supported filter capability checks.

Currently add support for:
<item>: IPv4, IPv6, TCP, and UDP.
<action>: Drop, Queue, and Count.

Also add sanity checks to ensure filters are created at specified
index in LE-TCAM region. The index in LE-TCAM region indicates
the filter rule's priority with index 0 having the highest priority.
If no index is specified, filters are created at closest available
free index.
