Sagi - From what I can tell, i40iw is also exposed to this same issue if the
IRQ affinity
is configured by user.
managed affinity does not allow setting smp_affinity from userspace.

Christoph, Sagi: it seems you think /proc/irq/$IRP/smp_affinity
shouldn't be allowed if drivers support managed affinity. Is that correct?
Not just shouldn't, but simply can't.
But as it stands, things are just plain borked if an rdma driver
supports ib_get_vector_affinity() yet the admin
