Remove the duplicate ovsDpdk property.
The v2 cpu schema now declares ovsDpdk twice: once at lines 512-518 and again at lines 531-536. A duplicate mapping key makes the manifest ambiguous, and YAML decoders keep only one value. YAMLlint reports this as an error.
The two blocks also carry different descriptions. The block at lines 512-518 matches the doc comment on CPU.OvsDpdk in pkg/apis/performanceprofile/v2/performanceprofile_types.go, so the generated CRD must use that text. Keep one entry in the alphabetical position (after offlined) and use the description that matches the API type, then regenerate the manifest.
🐛 Proposed fix: keep a single generated entry

@Tal-or, the concern is about regression-test coverage, not a functional failure.
The new code adds --ovs-dpdk-cpu-count only when a fixture has OvsDpdkCPUCount > 0.
Currently, the regression fixtures do not set a positive ovs-dpdk-cpu-count. Therefore, this test does not execute the new conditional path. It also does not compare generated spec.cpu.ovsDpdk output against an expected profile.
A minimal coverage addition would update one existing fixture pair:
- Add
"ovs-dpdk-cpu-count": <positive even value>to its JSON parameters file. - Add the matching
spec.cpu.ovsDpdkCPU set to its YAML expected profile.
The unit tests cover CPU-set allocation. This fixture would cover CLI argument forwarding and generated profile serialization together.

New tests with positive "ovs-dpdk-cpu-count" value were added to new created profile json (profile2c.json).
After running the test they did match the YAML expected profile (profile2c.yaml).

The function's signature become long and cumbersome.
I suggest to create a new struct:
type performanceProfileCPUSets struct {
reserved cpuset.CPUSet
isolated cpuset.CPUSet
offlined cpuset.CPUSet
ovsDpdk cpuset.CPUSet
}
use the new struct instead of 4 separated CPUSet objects.

Remove this change and we're good to go
Add a new performance-profile-creator flag, --ovs-dpdk-cpu-count, that reserves a dedicated set of CPUs for OVS-DPDK PMD threads and populates spec.cpu.ovsDpdk on the generated PerformanceProfile. It defaults to 0, leaving existing behavior unchanged. CalculateCPUSets now also returns the OVS-DPDK cpuset. Selection happens after reserved and offlined CPUs are chosen, drawing only from cores not already claimed, and the resulting CPUs are excluded from the isolated set. Allocation mirrors the reserved-CPU hyperthreading rules: with HT enabled it takes whole sibling groups and requires an even count; with HT off (or --disable-ht) it takes one logical processor per core.
