1. Update NetLib to a combined NetLib support dual network stack: 1) Add Network Debug facility for IPv4 stack. 2) Extend the library APIs to support IPv6 stack: a. NetIp6IsUnspecifiedAddr b. NetIp6IsLinkLocalAddr c. NetIp6IsNetEqual d. NetLibCreateIPv6DPathNode. e. NetIp6PseudoHeadChecksum f. NetIp6IsValidUnicast 3) Update the structure definitions: a. Update NET_BUF to add EFI_IP6_HEADER and EFI_UDP_HEADER b. Add NET_IP6_PSEUDO_HDR 4) Update Ip4IsUnicast to NetIp4IsUnicast 2. Update the impacted modules to adopt the combined NetLib. 3. Clean up coding style errors in all network drivers and libraries. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9391 6f19259b-4bc3-4df7-8a09-765794883524
