Module Name:    src
Committed By:   tsutsui

Modified Files:
        src/sys/arch/ews4800mips/sbd: if_iee_sbdio.c
        src/sys/arch/hp700/gsc: if_iee_gsc.c
        src/sys/dev/ic: i82596.c i82596var.h

Log Message:
Misc bus_dma(9) related cleanup:
- calculate each descriptor sizes and offsets in iee_attach() and store them
  into softc, rather than re-calculating them everywhere via macros
- prepare macros to sync DMA shmem per each descriptor
- sync only necessary descriptors in iee_intr() and iee_start()
- make sure SCB_FOO macros take softc as an arg properly
- use bus_dmamap_load_mbuf(9) for RX mbufs
- put 2 byte alignments to RX mbufs

XXX: still slower than ie(4) in i82586 compat mode on HP9000 735/125.
