Subject: tests/srp/rc: Avoid triggering "QP creation failed" error messages
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1cf827c8a1f2084638d8da2cf97c8d9612dc4938;p=users%2Fsagi%2Fblktests.git

tests/srp/rc: Avoid triggering "QP creation failed" error messages

Instead of trying to log in to each target port from each initiator
port, only log in to the target ports associated with the RDMA HCA
from which the log in request is sent. This avoids that the SRP
initiator driver logs the following error message when e.g.
attempting to log in to interface lo from an Ethernet interface:
"QP creation failed".
