> Since commit bacd75cfac8a ("i40e/i40evf: Add capability exchange for outer
> checksum", 2017-04-06) the i40e driver has not reported support for IP-in-IP
> offloads. This likely occurred due to a bad rebase, as the commit extracts
> hw_enc_features into its own variable. As part of this change, it dropped the
> NETIF_F_FSO_IPXIP flags from the
> netdev->hw_enc_features. This was unfortunately not caught during code
> review.
> 
> Fix this by adding back the missing feature flags.
> 
> For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa4a
> ("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20), replacing
> NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT.
> 
> NETIF_F_GSO_IPXIP6 was added in commit bf2d1df39502 ("intel: Add
> support for IPv6 IP-in-IP offload", 2016-05-20).
