Use network markers when a job needs real NIC hardware.

```yaml
xdp-tests:
  tags:
    - saas-linux-large-amd64
    - nic:tier:25g
    - nic:driver:mlx5_core
  variables:
    HW_NIC_TIER: "25g"
  script:
    - ./run-xdp-tests.sh
```

## Marker forms

- `nic:<driver>`
- `nic:driver:<driver>`
- `nic:speed:<mbps>`
- `nic:tier:1g`
- `nic:tier:10g`
- `nic:tier:25g`
- `nic:tier:40g`
- `nic:tier:100g`

For SR-IOV jobs, pair NIC markers with `HW_SRIOV_VF_COUNT`.
