Hi Roland,
We got a report that on a system with multiple (say two) ConnectX HCAs,
its possible
for the order of device probing to be different across simple reboots,
that is sometimes
the device with PCI BDF X is probed 1st and gets to be IB device mlx4_0
and some
other-timesthe device with BDF Y gets to be mlx4_0 and X becomes mlx4_1,
and so on,
which for some reason creates a hassle for them.
I don't fully understand how the PCI scan order can change between
different
reboots, but have the feeling its possible (in black box manner, the
reports claims that).
Thinking about this a bit, will it be possible to provide a udev
rulethat can dictate
to the IB core what name / suffix digit to assign for a device with
certain BDF?
Or.
