> Subject: [PATCH v2 1/2] net/i40e: fix link status change interrupt
> 
> Previously, link status interrupt in i40e is achieved by checking
> LINK_STAT_CHANGE_MASK in PFINT_ICR0 register which is provided only
> for diagnostic use. Instead, drivers need to get the link status
> change notification by using LSE (Link Status Event).
> 
> This patch enables LSE and calls LSC callback when the event is
> received. This patch also removes the processing on
> LINK_STAT_CHANGE_MASK.

> Fixes: 4861cde46116 ("i40e: new poll mode driver")
