from NetBSD. This driver actually can replace lnc(4). Advantages over lnc(4) are: - Cleaner and more flexible regarding MD needs. - Endian-clean and MPSAFE. - Supports ALTQ, VLAN_MTU, ifmedia. - Uses 32bit DMA for the PCI variants. This commit includes front-ends for the dma(4) pseudo-bus found on SBus- based sparc64 machines (thus supports the on-board LANCE in Sun Ultra 1) and PCI. In order to actually replace lnc(4), the front-ends for ISA and the PC98 CBUS would have to be added but for which I don't have hardware to test. Reviewed and some improvements by: yongari Tested on: i386, sparc64
