per-stack

Specify which CPU core interrupts for this stack should be handled on.

Onload interrupts are handled via net driver receive channel interrupts. The sfc_affinity driver is normally used to choose which net-driver receive channel is used, however this value can be used to override that mechanism.. It is only possible for interrupts to be handled on the requested core if a net driver interrupt is assigned to the selected core. Otherwise a nearby core will be selected.

Note: If the IRQ balancer service is enabled it can redirect interrupts to other cores.
