Continue hacking on esp driver. Seems relatively stable in read only mode.
...
write operations appear to lose scsi interrupts and causes timeouts.
changes in this checkin include:
a nextdma bugfix causing a diagnostic check to erroneously trigger
Changed tail strategy to only use tail buffer for the minimal end slop
changed expected write dma overrun to 32 bytes.
turned on nextdma diagnostic check for dma end address since it
no longer gets triggerred by ethernet dma and helps debug scsi dma.
