as a first attempt, I've followed your steps, but got:

Please install the sg3_utils package. Every Linux distro I know of =

I happened to do this test on a Fedora.

For ib_srp-backport, I get a lot of warnings like the following one,
at "make install" (preceded by corresponding warnings at the end of
the compilation):
depmod: WARNING: /lib/modules/4.16.0-rc1+/extra/ib_srp.ko needs =

Unfortunately, it gets worse while executing "make scst srpt":

Please neither install the ib_srp-backport driver nor SCST. These =

Install the following software packages if these have not yet been =

fio, gcc-c++, make, multipath-tools or device-mapper-multipath, =

sg3_utils,

srptools, e2fsprogs and xfsprogs.

Thank you very much for these instructions Bart.

After following all of them (and taking some other step needed), I
invoked:
sudo ./run_tests -c -d -r 10 -t 02-mq -e bfq

But I got the following:
./lib/functions: riga 34: /sys/class/block/ram0/size: No such file or =
directory
./lib/functions: riga 34: * 512: errore di sintassi: atteso un operando =

Unloaded the ib_srpt kernel module
Unloaded the rdma_rxe kernel module
modprobe: FATAL: Module ib_uverbs not found in directory =
/lib/modules/4.16.0-rc1+
modprobe: FATAL: Module ib_umad not found in directory =
/lib/modules/4.16.0-rc1+
SoftRoCE network interfaces: rxe0
modprobe: FATAL: Module target_core_iblock not found in directory =
/lib/modules/4.16.0-rc1+

So I think I need a little more help, to have this working in a
reasonable amount of time.  In particular, could you tell me all what
is missing?

Thanks,
Paolo
