====================
Intel Wired LAN Driver Updates 2020-09-09

This series contains updates to i40e and igc drivers.

Stefan Assmann changes num_vlans to u16 to fix may be used uninitialized
error and propagates error in i40_set_vsi_promisc() for i40e.

Vinicius corrects timestamping latency values for i225 devices and
accounts for TX timestamping delay for igc.
