For example, on device reset the driver frees the\nrmap right before allocating a new one (the splat above).\nMake rmap creation and freeing function symmetrical with\n{request,free}_irq() calls i.e. do that on ifup/ifdown instead\nof device probe/remove/resume. These operations can be performed\nindependently from the actual device aRFS configuration.\nAlso, make sure ice_vsi_free_irq() clears IRQ affinity notifiers\nonly when aRFS is disabled -- otherwise, CPU rmap sets and clears\nits own and they must not be touched manually." |
