[v4] net/i40e: fix link status
Checks
Commit Message
If the PF driver supports the new speed reporting capabilities
then use link_event_adv instead of link_event to get the speed.
Fixes: 2a73125b7041 ("i40evf: fix link info update")

v4:
* fix compilation issue in meson build
v3:
* request the capability for i40evf
v2:
* modify commit log
