Subject: Re: [edk2-devel] [PATCH v2] RedfishPkg: RedfishDiscoverDxe: Fix issue if IPv4 installed after RestEx
Date: Thu, 2 Nov 2023 02:56:57 +0000	[thread overview]
Message-ID: <MW4PR12MB7031BE43AB814C0DAF029828D9A6A@MW4PR12MB7031.namprd12.prod.outlook.com> (raw)
In-Reply-To: <20231101201704.1504-1-igork@ami.com>

This change looks good to me. Just minor comments:

> DEBUG ((DEBUG_INFO, "%a: all required protocols are found on this controller handle: %p.\n", __func__, ControllerHandle));

Could we use DEBUG_MANAGEABILITY to replace DEBUG_INFO in Redfish driver? This gives us the way to show manageability information only while debugging.

And it looks like we don't run uncrustify to this patch. May I know if it is possible to create a PR on edk2 repository and edk2 CI can test it? Edk2 CI helps me to catch some formatting issue that I am not aware of.

Thanks,
Nickle
