[PATCH 05/19] net: Move SYS_RX_ETH_BUFFER into the network menu

[Simon Glass]

Move this Kconfig option into the correct place, so it doesn't show up
in the top-level menu.

Unfortunately this makes the CONFIG undefined on some boards which don't
enable CONFIG_NET but do include the net.h header file. In fact that
header is included from a lot of common places. So use a fallback in the
header file.
