[ Upstream commit ba766b8b99c30ad3c55ed8cf224d1185ecff1476 ]
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).
