-/* The block size is currently chosen to be 512 bytes. This means, we can
-   allocate the receive buffer on the stack, but it results in a noticeable
-   performance penalty.
-   This is what needs to be done in order to increase the block size:
-     - size negotiation needs to be implemented in TCP
-     - the buffer needs to be allocated on the heap
-     - path MTU discovery needs to be implemented
