The Makefile file is not actually part of the source tree: it is
generated by configure in the build tree (from the Makefile.in file in
the source tree).  So it's better to list some file like a .c file:
  AC_CONFIG_SRCDIR([src/basic_utilities/show_hardware_info.c])

Automake's options need to be listed space-separated here.
I think the commas will pretty much cause it to ignore all
but the first option.

Do you actually need this?  It is necessary only if you have another
configure script in src/.

It looks like you should list
  src/Makefile

here, too.  Wait: wouldn't that be 
  src/ethernet_tests/Makefile

instead of
  ethernet_tests/Makefile

and likewise for the other Makefiles?  That explains the errors you are
seeing.

You don't need this line if you add
  foreign

to the list of options as argument to AM_INIT_AUTOMAKE in configure.ac.

You don't need this line if you put
  AC_SUBST([EXTRA_CFLAGS], ...)

in configure.ac.

Same issues in the other Makefile.am files.

You don't need this line.

Hope that helps.
