There's some NICs, such as hinic, with NETIF_F_IP_CSUM and NETIF_F_TSO
on but NETIF_F_HW_CSUM off. And ipvlan device features will be
NETIF_F_TSO on with NETIF_F_IP_CSUM and NETIF_F_IP_CSUM both off as
IPVLAN_FEATURES only care about NETIF_F_HW_CSUM. So TSO will be
disabled in netdev_fix_features.
For example:
Features for enp129s0f0:
rx-checksumming: on
tx-checksumming: on
tx-checksum-ipv4: on
tx-checksum-ip-generic: off [fixed]
tx-checksum-ipv6: on
