However __netif_rx() can only be called from interrupt context.\nChange the call to netif_rx() in order to allow completion via normal\ncontext for dmaengine drivers that utilize threaded irq handling.\n\nWhile the following commit changed from netif_rx() to __netif_rx(),\nbaebdf48c360 (\"net: dev: Makes sure netif_rx() can be invoked in any context.\"),\nthe change should've been a noop instead. However, the code precedes this\nfix should've been using netif_rx_ni() or netif_rx_any_context()."
