No.
The max_interrupt_work value is used in the main interrupt loop. I shouldn't
be used again in the *_rx() routine.
The intent of max_interrupt_work is to
- give other devices on the same IRQ a chance to do work under very high
workload
- to avoid unexpected hardware operation from locking up the machine
(commonly this isn't a hardware sample flaw, but a unanticipated "can't
clear the interrupt)
IMNSHO, no device driver should have unlimited loops. A quick scan of other
drivers shows that I am in the minority in that viewpoint.
