Currently the IRQ affinity settings are getting lost when interface
goes through a soft reset (due to MTU configuration, changing number
of queues etc). Use irq_set_affinity_notifier() callbacks to keep
the IRQ affinity info in sync between driver and kernel.
Could you try doing this in the core? Store the mask in napi_struct
if it has IRQ associated with it?
Barely any drivers get this right.
The napi structs are allocated/freed with open/close ndos. I don't think
we should expect the user to re-set CPU affinity after link down/up.
netdev->_rx perhaps?
