John Crispin a2708d11e8 ramips: Rework ramips_eth to not require irqsave locking anymore ... Previously the tx housekeeping was done in a spin_lock_irqsave critical section which causes irqs to be disabled during that time. Since the housekeeping is already prepared to be scheduled as a tasklet process the housekeeping only in softirq context and revise the locking between the tx path and the housekeeping tasklet by using a normal spin_lock which in most situations will be a NOP anyway. This makes sure that interrupts are only disabled for a short time since in the worst case the housekeeping might have to free up to 256 skbs.
