Firmware advertises the transfer lenght for writesame commands to driver during init.
So for any writesame IOs with ndob and unmap bit set and transfer lengh is greater
than the max write same length specified by the firmware, then direct those commands
to firmware instead of hardware otherwise hardware will break.

This is Broadcom's mpi3mr driver for FreeBSD version 8.6.0.2.0.
The mpi3mr driver supports Broadcom SAS4116-based cards in the 9600
series: 9670W-16i, 9670-24i, 9660-16i, 9620-16i, 9600-24i, 9600-16i,
9600W-16e, 9600-16e, 9600-8i8e.
Initially only available as a module and on amd64/arm64, since that's
how it has been tested to date. Future commits will add it to the kernel
build and may expand the architectures it is supported on.
