ewrk3/tulip: Move the DEC - Tulip drivers
Move the DEC - Tulip driver into drivers/net/ethernet/dec/tulip/ and make the necessary Kconfig and Makefile changes. The Digital Equioment (DEC) driver ewrk3 was moved into drivers/net/ethernet/dec/ and the remaining drivers (Tulip) were moved into drivers/net/ethernet/dec/tulip/ CC: Tobias Ringstrom <tori@unhappy.mine.nu> CC: Grant Grundler <grundler@parisc-linux.org> CC: David Davies <davies@maniac.ultranet.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Acked-by: Grant Grundler <grundler@parisc-linux.org>
