When running ibstat (if transceiver is not connected in adapter):

Any output before that ?
no, It only prints this line.
and setting the width to 1x in the driver so the rate file is properly
populated fixes this ?
Yes, because a value is written in
/sys/class/infiniband/mlx5_X/ports/1/rate
I must be missing something as to what is going
on in this scenario.
Without this bug fix, file /sys/class/infiniband/mlx5_X/ports/1/rate is
empty, which results in ibpanic.

sysfs.c:rate_show is inconsistent as it paves over an invalid speed
setting that to SDR but does not pave over invalid width returning
-EINVAL but this comment is in another "direction".

I'm trying to understand how far it gets. It
looks to me that empty rate file would be parsed as 0 and ibstat would
show that rate. ibpanic would occur if file was not found but I could be
missing something.
