Such a check wouldn't be that simple because the only way to perform such a

The other option woud be to disallow gappy SG lists unless supported by
the hardware with a single MR similar to iSER. While this would leave
the SRP protocol support for multiple SG entries per command unused it
would significantly simplify the driver.
Hello Christoph,
I will have a look into this after the kernel 4.4 merge window has been
closed.
Bart.
