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.
Fixes: 4861333b4217 ("bonding: add ESP offload features when slaves support")
