This could really benefit from some helper macros.
e.g. if the test could look like

(VALID_TCP6 (TargetNetworkInterface, ThisNetworkInterface) ||
VALID_TCP4 (TargetNetworkInterface, ThisNetworkInterface))) {

If this is just a local helper function, we probably want it STATIC.

Similarly, this becomes a bit of a handful.
But it also feels like the logic is incorrect?
I.e. it won't filter out entries where IpType ==
REDFISH_HOST_INTERFACE_HOST_IP_ADDRESS_FORMAT_UNKNOWN, or invalid?
Shouldn't the test be
((gRequiredProtocol[Index].ProtocolType == ProtocolTypeTcp4) &&
(IpType != REDFISH_HOST_INTERFACE_HOST_IP_ADDRESS_FORMAT_IP4))
and
((gRequiredProtocol[Index].ProtocolType == ProtocolTypeTcp6) &&
(IpType != REDFISH_HOST_INTERFACE_HOST_IP_ADDRESS_FORMAT_IP6)))
Either way, those tests could probably also do with being turned into
macros to improve readability.

[AMD Official Use Only - General]
Thanks Leif, some responses are given in line.
As we would like to have this be part of edk2-stable202312, we prefer letting this change gets in stable release first and address the comment in another patch afterward.
Hi Igor,
Could you please check my comment and help to send another patch after edk2-stable202312?
Thanks
Abner

However, it is recommended that not using STATIC for local function for the source level debug purpose in 5.4.2.2.2 in edk2 C coding standard spec.

Igor, could we consider using MACRO for this as well?

I think above is the error condition, thus there is a "continue" to skip this entry.

Yeah, we need to fix that doc. I have no idea what decade that comment

We would like to include this fix to edk2-stable202311 release. Could you
please help us to merge this patch? This patch review was started on
November 1: https://edk2.groups.io/g/devel/message/110440. Anber and I gave
reviewed-by to this patch today. We have a pull request ready for merging
here: https://github.com/tianocore/edk2/pull/4994
Thanks,
Nickle

(You have my old now-dysfunctional @nuviainc.com email address on cc,
please delete that one if you can.)
I think it's fine to merge this bugfix, but I have a couple of review
comments I will make on the v3 code itself, replying to that submission.
(I am however not the maintainer of RedFishPkg, so Nickle is free to
ignore me and push this version.)
