1. Support netboot6 tftp URL format like tftp://[aaaa::bbbb]/myfile.efi;mode=octet, other mode is rejected.
2. Fix bug in PXE driver UdpRead function to handle the IP fragmentation. Signed-off-by: sfu5 Reviewed-by: xdu2 Reviewed-by: hhuan13 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12308 6f19259b-4bc3-4df7-8a09-765794883524
