However, enetc_xdp_drop() is also used in XDP_TX and XDP_REDIRECT actions. If frame loss occurs in these two actions, the frames loss count should not be included in xdp_drops, because there are already xdp_tx_drops and xdp_redirect_failures to count the frame loss of these two actions, so it's better to remove xdp_drops statistic from enetc_xdp_drop() and increase xdp_drops in XDP_DROP action.
