The fixed commit adds NETIF_F_GSO_ESP bit for bonding gso_partial_features. However, if we don't set the dev NETIF_F_GSO_PARTIAL bit, the later netdev_change_features() -> netdev_fix_features() will remove the NETIF_F_GSO_ESP bit from the dev features. This causes ethtool to show that the bond does not support tx-esp-segmentation. For example
# ethtool -k bond0 | grep esp tx-esp-segmentation: off [requested on] esp-hw-offload: on esp-tx-csum-hw-offload: on
Add the NETIF_F_GSO_PARTIAL bit to bond dev features when set gso_partial_features to fix this issue.
