9604e7689d
- Add support for byte system bus mode. Based on patch in kern/17193 by Christian Groessler, with some improvements by me. - Rename sc_flags in mb86960_softc to sc_stat, rename "type" to sc_flags to specify controller quirks and remove enum mb86960_type. - Pass controller type via new sc_flags in mb86960_softc rather than via an mb86960_attach() arg. - Handle unaligned mbufs properly in mb86960_write_mbufs(). (from ne2000.c) - Fix a signed/unsigned comparision warning. - Add definitions of status bits in the RX packed header. - Change types of some members in mb86960_softc.
