Public bug reported:
[Impact]
Using IPv4-specific APIs during NIC setup based on iBFT information, regardless
of the IP version, results in the following error in IPv6-only environments:
Setting up software interface ens300f0np0
iscsistart: Invalid or missing ipaddr in fw entry
Setting up software interface ens300f0np0 failed
[Fix]
Upstream has a patch to resolve this issue.

IPv6 support for iBFT iSCSI boot (#493)
* Avoid reassigning a char pointer variable to a newly allocated
string
Introduce two separate variables to clearly distinguish their usage.

* IPv6 support for iBFT iSCSI boot
Use IPv4-specific APIs during NIC setup based on iBFT information,
regardless of the IP version, which leads to the following error
in IPv6-only environments:
Setting up software interface ens300f0np0
iscsistart: Invalid or missing ipaddr in fw entry
Setting up software interface ens300f0np0 failed
To address this, the process now determines the IP version first
and calls the appropriate functions to handle NIC setup.

[Test Plan]
1. Set up a machine with an iSCSI backend in an IPv6-only environment.
2. Power on the machine and verify that the following error does not occur:
Setting up software interface ens300f0np0
iscsistart: Invalid or missing ipaddr in fw entry
Setting up software interface ens300f0np0 failed
3. Ensure that the machine can successfully boot via iSCSI in an IPv4
environment.
[Where problems could occur]
The fix primarily adds IPv6 support for iBFT iSCSI boot and should not impact
the IPv4 scenario. However, if any regressions occur, the iBFT iSCSI boot
mechanism may be affected, potentially preventing the machine from booting via
iSCSI.
