This fix attempts to solve a customer (IBM) reported issue with NAPI enabled e1000 having bad performance when transmitting simultaneously on four ports. The issue comes down to an interaction between NAPI, hardware interrupt balancing, and the driver rescheduling poll on the same processor. Try to fix by allowing the driver to re-enable interrupts sooner instead of polling one more time, when there was recently all the work completed in cleanup.
