It is not easy to fix. Need put tx to NAPI poll function.
I will work on that after China New year holiday

Converting Tx to NAPI is the best solution, but you can put a temporary fix
in.  Don't take a spin_lock() in fec_enet_tx(), rather take a
spin_lock_irqsave() since you're still in HARDIRQ context.

That's not help.
skb_tx_timestamp function call some function using lock, which lock
used at the other place, just call spinlock_bh.

skb_tx_timestamp seem be called only in softirq context, not irq context.
