Instead of selecting REGEX when NET is enabled, make it the default, but allow boards that are tiny to disable it and lose functionality on all but the first Ethernet adapter. cm-bf548, bf538f-ezkit, and bf533-stamp need this. None appear to have more than one Ethernet interface. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
