In brcmf_rx_frames() the call to brcmf_fweh_process_skb() could change the ifidx using information in the event data. This is only different to the BDC ifidx for IF ADD event. However, the creation of the new interface is deferred to event worker so it does not exist. After brcmf_fweh_process_skb() it is only used to set statistics.
