Miller 1257995016 -0800 gianfar: Revive SKB recycling Before calling gfar_clean_tx_ring() the driver grabs an irqsave spinlock, and then tries to recycle skbs. But since skb_recycle_check() returns 0 with IRQs disabled, we'll never recycle any skbs. It appears that gfar_clean_tx_ring() and gfar_start_xmit() are mostly idependent and can work in parallel, except when they modify num_txbdfree. So we can drop the lock from most sections and thus fix the skb recycling. Signed-off-by: Anton Vorontsov Acked-by: Kumar Gala Signed-off-by: David S. Miller งา
