i40e NIC no longer working

[mzac]

Running Intel X710-DA4 NICs and they are no longer showing up since upgrading to 5.4.0-97 from 5.4.0-96.

Note that we are running pf_ring ZC on this system and we are getting errors.

The interfaces no longer show up with ifconfig either after boot however they are seen in dmesg.
