1. Proposed title of this feature request
Using sysctl to disable IPv6 at the adapter level

2. What is the nature and description of the request?
It's currently not supported to disable IPv6 using the kernel parameter
But this should be simply achievable to disable it on the external adapter using the sysctl config: net.ipv6.conf.<interface>.disable_ipv6 = 1

3. Why does the customer need this? (List the business requirements here)
Some customer want to limit the network traffic to IPv4 only and are trying to ensure their nodes are not accessible via IPv6.

4. List any affected packages or components.
This should simply require to set the setting net.ipv6.conf.<interface>.disable_ipv6 to 1 on the desired adapters using the tuned operator.
