Description of problem:
since minTxRate is not supported for Intel card. So we should validate when creating sriovnetwork. 

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  init intel VF with following CR:
 apiVersion: sriovnetwork.openshift.io/v1
kind: SriovNetworkNodePolicy
metadata:
  name: intel-netdevice
  namespace: openshift-sriov-network-operator
spec:
  deviceType: netdevice
  mtu: 1500
  nicSelector:
    pfNames:
      - ens1f0
    rootDevices:
      - '0000:3b:00.0'
    vendor: '8086'
  nodeSelector:
    feature.node.kubernetes.io/sriov-capable: 'true'
  numVfs: 5
  priority: 99
  resourceName: intelnetdevice
2. Create sriovnetwork with minTxRate: 

apiVersion: sriovnetwork.openshift.io/v1
kind: SriovNetwork
metadata:
  name: static-sriovnetwork
  namespace: openshift-sriov-network-operator
spec:
  ipam: |
    {
      "type": "static"
    }
  capabilities: |
    {
      "mac": true,
      "ips": true
    }
  vlan: 0
  maxTxRate: 100
  minTxRate: 40
  spoofChk: "on"
  trust: "off"
  resourceName: intelnetdevice
  networkNamespace: z2
3. create pod with above net-attach-def

Actual results:

Pod cannot be created and it will also block the VF, see another bug: Red Hathttps://bugzilla.redhat.com/show_bug.cgi?id=1772815


Expected results:
should block When creating sriovnetwork with minTxRate for intel resource.
