Subject: [PATCH 01/15] net: introduce legacy dir to absorb 10Mbit, ISA, EISA drivers

There are lots of drivers that date back to the early 1990's when
Linux was started, and they correspond to hardware and bus
technologies that have largely disappeared from in-use hardware over
10 years ago.

There is no need to have these drivers polluting the namespace
in the top level drivers directory any longer; relocation to a
subdirectory is long overdue.  Start by creating this new home
for these drivers so that they can be targeted and relocated.

By leaving the default to include the legacy/Kconfig, we ensure
people who have existing stores of their own .config files will
not have drivers silently dropped from their builds.

Since the legacy drivers have their probe ordering defined in
the Space.c file, we don't have to strictly maintain any link
order in moving things from Makefile to legacy/Makefile.
