selftests: net: tcp_mmap: Use huge pages in send path

Browse source

There are significant gains using huge pages when
available, as shown in [1].

This patch adds mmap_large_buffer() and uses it
in client side (tx path of this reference tool)

Following patch will use the feature for server side.
