src/sys/dev/ic: ld_nvme.c nvme.c nvmevar.h
Log Message:
pass maxphys from device rather then assuming MAXPHYS; it's clipped in ld(4)
if bigger then MAXPHYS
multiply the queue size by number of queues for ld(4) sc_maxqueuecnt, so
that ld_diskstart() would try to use full capacity, instead of throttling
to one queue worth of commands
