The flags are typically computed by calling ieee80211_set_sdata_offload_flags for a vif before a drv_add_interface or drv_update_vif_offload call, which allows the driver to set the offload flags to their final state. I think the right approach for fixing this is to change ieee80211_check_fast_rx to make it check the vif offload flag for the bss sdata instead of the AP_VLAN vif. - Felix

The WDS interface whose iftype is NL80211_IFTYPE_AP_VLAN can not be enabled rx decap offload because its offload_flags is not configured. The offload_flags of wds interface shall be configured by checking hardware information.
