In addition to the .add_interface op, a .update_vif_offload op is +introduced, which can be used for runtime changes. + +If a driver can't disable encap offload at runtime, or if it has some extra +limitations, it can simply override the flags within those ops. + +Support for encap offload with 4-address mode interfaces can be enabled +by setting a flag from .add_interface or .update_vif_offload. + +Signed-off-by: Felix Fietkau <nbd@nbd.name> +--- + +--- a/drivers/net/wireless/ath/ath11k/mac.c ++++ b/drivers/net/wireless/ath/ath11k/mac.c +@@ -4150,6 +4150,35 @@ static int ath11k_set_he_mu_sounding_mod + return ret; + } + ++static void ath11k_mac_op_update_vif_offload(struct ieee80211_hw *hw, ++ struct ieee80211_vif *vif) ++{ ++ struct ath11k *ar = hw->priv; ++ struct ath11k_base *ab = ar->ab; ++ struct ath11k_vif *arvif = ath11k_vif_to_arvif(vif); ++ u32 param_id, param_value; ++ int ret; ++ ++ param_id = WMI_VDEV_PARAM_TX_ENCAP_TYPE; ++ if (ath11k_frame_mode != ATH11K_HW_TXRX_ETHERNET || ++ (vif->type != NL80211_IFTYPE_STATION && ++ vif->type != NL80211_IFTYPE_AP)) ++ vif->offload_flags &= ~IEEE80211_OFFLOAD_ENCAP_ENABLED; ++ ++ if (vif->offload_flags & IEEE80211_OFFLOAD_ENCAP_ENABLED) ++ param_value = ATH11K_HW_TXRX_ETHERNET; ++ else ++ param_value = ATH11K_HW_TXRX_NATIVE_WIFI; ++ ++ ret = ath11k_wmi_vdev_set_param_cmd(ar, arvif->vdev_id, ++ param_id, param_value); ++ if (ret) { ++ ath11k_warn(ab, "failed to set vdev %d tx encap mode: %d\n", ++ arvif->vdev_id, ret); ++ vif->offload_flags &= ~IEEE80211_OFFLOAD_ENCAP_ENABLED; ++ } ++} ++ + static int ath11k_mac_op_add_interface(struct ieee80211_hw *hw, + struct ieee80211_vif *vif) + { +@@ -4159,7 +4188,6 @@ static int ath11k_mac_op_add_interface(s + struct vdev_create_params vdev_param = {0}; + struct peer_create_params peer_param; + u32 param_id, param_value; +- int hw_encap = 0; + u16 nss; + int i; + int ret; +@@ -4253,30 +4281,7 @@ static int ath11k_mac_op_add_interface(s + list_add(&arvif->list, &ar->arvifs); + spin_unlock_bh(&ar->data_lock); + +- param_id = WMI_VDEV_PARAM_TX_ENCAP_TYPE; +- if (ath11k_frame_mode == ATH11K_HW_TXRX_ETHERNET) +- switch (vif->type) { +- case NL80211_IFTYPE_STATION: +- case NL80211_IFTYPE_AP_VLAN: +- case NL80211_IFTYPE_AP: +- hw_encap = 1; +- break; +- default: +- break; +- } +- +- if (ieee80211_set_hw_80211_encap(vif, hw_encap)) +- param_value = ATH11K_HW_TXRX_ETHERNET; +- else +- param_value = ATH11K_HW_TXRX_NATIVE_WIFI; +- +- ret = ath11k_wmi_vdev_set_param_cmd(ar, arvif->vdev_id, +- param_id, param_value); +- if (ret) { +- ath11k_warn(ab, "failed to set vdev %d tx encap mode: %d\n", +- arvif->vdev_id, ret); +- goto err_vdev_del; +- } ++ ath11k_mac_op_update_vif_offload(hw, vif); + + nss = get_num_chains(ar->cfg_tx_chainmask) ?
