[PATCH V3 blktests 0/5] nvmeof-mp/srp/nvme-rdma misc fix and enhancement

[Yi Zhang]

Hi

This patch series addressed some failures when I run nvmeof-mp/srp
test and also add suport to use siw for nvme-rdma/nvmeof-mp/srp  testing
from cmdline, like this:

$ use_siw=1 nvme-trtype=rdma ./check nvme
$ use_siw=1 ./check nvmeof-mp
$ use_siw-1 ./check srp

V3:
Use sed to output the scheduler from sysfs directly in patch 3

V2:
Update the ib_srpt module path in patch 1, avoid to use ls
Update the SKIP_REASON in patch 2
Introduce get_scheduler_list, fix nvmeof-mp/012 and srp/012 in patch 3
Typo fix in patch 4

Yi Zhang (5):
  tests/srp/rc: update the ib_srpt module name
  tests/nvmeof-mp/rc: run nvmeof-mp tests if we set multipath=N
  nvmeof-mp/012, srp/012: fix the scheduler list
  common/rc: _have_iproute2 fix for "ip -V" change
  common/multipath-over-rdma: allow to set use_siw

[PATCH V3 blktests 3/5] nvmeof-mp/012, srp/012: fix the scheduler list

There is no cfq scheduler and new added kyber scheduler in lastest kernel,
introduce get_scheduler_list and fix nvmeof-mp/012 srp/012

To reproduce it:
$ ./check nvmeof-mp/012
nvmeof-mp/012 (dm-mpath on top of multiple I/O schedulers)   [passed]

[PATCH V3 blktests 5/5] common/multipath-over-rdma: allow to set use_siw

[Yi Zhang]

With this change, we can change to use siw for nvme-rdma/nvmeof-mp/srp
testing from cmdline:

$ use_siw=1 nvme-trtype=rdma ./check nvme/
$ use_siw=1 ./check nvmeof-mp/
$ use_siw=1 ./check srp/
