Hi Lubo,

        Please find the following details that may help.

NetworkPkg:Fix a bug the 2nd httpboot fail issue.

Httpboot over Ipv4 or Ipv6 stack,for both Identity and chunked transfer 
mode,when the last data has been parsed by HttpLib, the HttpInstance->NextMsg 
pointer should point a correct location.Now after the first  successful 
httpboot for ipv4 or ipv6,the HttpInstance->NextMsgpoint the character after 
the last byte, it may be a bad buffer if we don't receive another HttpHeader, 
so if call a 2nd httpboot, the wrong NextMsg pointer will cause the httpboot 
fail, so we need to check this case in HttpBodyParserCallback function in the 
first http boot process.

Hello,

          Revision 24729 of edk2 says 2nd HttpBoot fail issue has been fixed. 
So, I have taken the changes from the file NetworkPkg/HttpDxe/HttpImpl.c of the 
revsision 24729 and still the 2nd  HttpBoot fails. Please let me know if I have 
missed any.

P.S: The first http boot happens successfully though. (downloading a Shell.efi)

Thanks,
Naveen
