commit 9946b783844d3dd369d99acd3fe333b1667c3042
Author: Antonio Borneo <bor...@gm...>

    configure.ac: add adapter dependency from sys/mman.h
    
    The adapter's driver that require the header file sys/mman.h
    should check for it and don't compile if it is not present.
    
    Add the check for sys/mman.h in configure.ac and prevent the
    build of the adapter's driver that depend on it.
