describeNetworkInterfaces  
  inline suspend fun Ec2Client.describeNetworkInterfaces(crossinline block: DescribeNetworkInterfacesRequest.Builder.() -> Unit): DescribeNetworkInterfacesResponse
Describes the specified network interfaces or all your network interfaces.
If you have a large number of network interfaces, the operation fails unless you use pagination or one of the following filters: group-id, mac-address, private-dns-name, private-ip-address, subnet-id, or vpc-id.
We strongly recommend using only paginated requests. Unpaginated requests are susceptible to throttling and timeouts.
