Ah, now I see that the GRE support patch for i40e_tx_enable_csum() hasn't been pushed out yet. This explains some of this discussion. Okay - for the moment we're dropping this patch, to be reworked when the other patch gets pushed.
I think you're right about simply dropping the use of vxlan_features_check() as it is too specific for our needs. This will be part of the rework.
