This API is used to create an ENI and bind it to a CVM.

• You can specify private IP addresses and a primary IP when creating an ENI. The specified private IP must be idle and in the same subnet as the ENI.
• When creating an ENI, you can specify the number of private IPs that you want to apply for. The system will randomly generate private IP addresses.
• The number of IPs bound with an ENI is limited. For more information, see ENI Use Limits.
• You can bind an existing security group when creating an ENI.
• You can bind a tag when creating an ENI. The tag list in the response indicates the tags that have been successfully added.

  Note：
