+static void +ice_set_rx_rings_vlan_proto(struct ice_vsi *vsi, __be16 vlan_ethertype)@vsi can be const (I hope).I will try to make it const.quoted
Line can be broken on arguments, not type (I hope).This is how we break the lines everywhere in this file though :/
I know and would really like us stop at least adding new such occurrences when not needed :s

- vlan_tag = ice_get_vlan_tag_from_rx_desc(rx_desc); + vlan_tci = ice_get_vlan_tci(rx_desc);Unrelated: I never was a fan of scattering rx_desc parsing across several files, I remember I moved it to process_skb_fields() in both ice (Hints series) and iavf (libie), maybe do that here as well? Or way too out of context?A little bit too unrelated to the purpose of the series, but a thing we must do in the future.
Sure, +
