>ixgbe_txrx_ring_{dis, en}able
>
>Currently routines that are supposed to toggle state of ring pair do not take
>care of associated interrupt with queue vector that these rings belong to. This
>causes funky issues such as dead interface due to irq misconfiguration, as per
>Pavel's report from Closes: tag.
>
>Add a function responsible for disabling single IRQ in EIMC register and call
>this
>as a very first thing when disabling ring pair during xsk_pool setup. For
>enable
>let's reuse ixgbe_irq_enable_queues(). Besides this, disable/enable NAPI as
>first/last thing when dealing with closing or opening ring pair that xsk_pool
>is
>being configured on.
