mlx4_en: Fix a kernel panic when waking tx queue When the transmit queue gets full we enable interrupts for TX completions There was a race that we handled the TX queue both from the interrupt context and from the transmit function. Using "spin_trylock_irq()" ensures this doesn't happen. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
