2f64a5c772 replace tcpip_input by ethernet_input/ip_input 
All MetalSVM drivers guarantee that the input function will be called in the context of the tcpip thread.
Therefore, we are able to use ethernet_input/ip_input instead of tcpip_input

Stefan Lankes
24914fcb4f add prototype of a tickless kernel 
only by entering the kernel, the tick counter will be updated
=> by using this feature, MetalSVM supports only LwIP's raw interface,
   because we have no guarantee that the tcpip thread will get computation time
=> no NETCONN & BSD socket support
=> no load balancing support

227cc19890 add alpha version of x64 support 
New features:
- support of kernel tasks in 64bit mode
- support of LwIP in 64bit mode

Missing features in 64bit mode
- user-level support
- APIC support => SMP support

To create a 64bit version of the MetalSVM kernel, the compiler flags “-m64 -mno-red-zone” and the assembler flags “-felf64” has to be used. Please use qemu-system-x86_64 as test platform.

Notice, metalsvm.elf is a 32bit ELF file. However, it contains (beside the startup code) only 64bit code. This is required because GRUB doesn’t boot 64bit ELF kernels. Therefore, for disassembling via objdump the flag  “-M x86-64” has to be used.
