>Description:
	the following is the first i/o request of
	"dd if=/dev/rsd0c of=/dev/null", after biodone() is called on it.

		db> sh buf 0xfffffc001dde6458
		  vp 0x0 lblkno 0xdeadbeefdeadbeef blkno 0x0 dev 0x802
		  error 0 flags 0x1c0210<BUSY,DONE,PHYS,RAW,READ>
		  bufsize 0x200 bcount 0x200 resid 0x200
		  data 0x120018000 saveaddr 0x0 dep 0x0
		  iodone 0xfffffc0000480420

	after putting some printf,
	esiop_intr seems to call esiop_scsicmd_end with offset == 0.
