[PATCH v3 0/2] nvme-fabrics: short-circuit connect retries

[Daniel Wagner <dwagner@suse.de>]

I've picked up Hannes' DNR patches. In short the make the transports behave the
same way when the DNR bit set on a re-connect attempt. We had a discussion this
topic in the past and if I got this right we all agreed is that the host should
honor the DNR bit on a connect attempt [1]

The nvme/045 test case (authentication tests) in blktests is a good test case
for this after extending it slightly. TCP and RDMA try to reconnect with an
invalid key over and over again, while loop and FC stop after the first fail.
