Subject: [PATCH 4/4] Changes for adding keyfile support in RHEL specific
script
RH-Author: Ani Sinha <anisinha@redhat.com>

RH-Commit: [4/4] b60a8d644b0e777373c92f4778c3d4560f6f2642 (anisinha/centos-hyperv-daemons)
Some adjustments to the RHEL specific customization script in order to support
Network Manager keyfiles. These changes were tested internally by Red Hat QE.
These changes are mostly trivial and are not pushed upstream at this momemnt.

Subject: [PATCH 3/4] hv/hv_kvp_daemon: Handle IPv4 and Ipv6 combination for
keyfile format
RH-Author: Ani Sinha <anisinha@redhat.com>

RH-Commit: [3/4] e164b6951b873467f8c87e0d01b1fd89326aa64e (anisinha/centos-hyperv-daemons)
If the network configuration strings are passed as a combination of IPv4
and IPv6 addresses, the current KVP daemon does not handle processing for
the keyfile configuration format.
With these changes, the keyfile config generation logic scans through the
list twice to generate IPv4 and IPv6 sections for the configuration files
to handle this support.
Testcases ran:Rhel 9, Hyper-V VMs
(IPv4 only, IPv6 only, IPv4 and IPv6 combination)

RH-Commit: [2/4] 1676c48ed1f2d91dd1f8c43f6c8009e3bebf295a (anisinha/centos-hyperv-daemons)
Some small fixes:
- lets make sure we are not adding ipv4 addresses in ipv6 section in
keyfile and vice versa.
- ADDR_FAMILY_IPV6 is a bit in addr_family. Test that bit instead of
checking the whole value of addr_family.
- Some trivial fixes in hv_set_ifconfig.sh.
These fixes are proposed after doing some internal testing at Red Hat.

RH-Commit: [1/4] 0cb079b0cc30bef47bddd193e262dfa52b7f2874 (anisinha/centos-hyperv-daemons)
Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig
The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.
