Re: [Patch 0/2] Add IPv6 support condition check for HTTP/ISCSI.

["Wu, Jiaxin" <jiaxin.wu@intel.com>]

Hi Karunakar,

If you have no more comments, can you reply the below series patches with Reviewed-by/Tested-By tags, then I can go on the commit process?

[Patch v3 0/3] NetworkPkg/IScsiDxe: Display InitiatorInfo correctly.
            NetworkPkg/IScsiDxe: Fix the incorrect/needless DHCP process.
            NetworkPkg/IScsiDxe: Clean the previous ConfigData when switching the IP mode. /// This one is to fix the issue A.
            NetworkPkg/IScsiDxe: Display InitiatorInfo in attempt page even DHCP enabled. 

[Patch v2 0/2] Add IPv6 support condition check.
             NetworkPkg/HttpBootDxe: Add IPv6 support condition check. /// B  && C have been fixed in version 2.
             NetworkPkg/IScsiDxe: Add IPv6 support condition check.

Thanks,
Jiaxin
