Fix interrupt storm on bone A4 cause by non-by-the-book interrupt handling.
While at it, added a non-NAPI mode (which is easier to debug), plus
some general fixes.

I have tested CPSW on AM335x EVM 1.5A with flood ping and i am not
seeing any interrupt storm.
Can you provide more details on how to reproduce the issue.
A beaglebone prototype with the new silicon version, with the ethernet errata
fixed displays this. You can't trigger it on old silicon.
The TI people on the CC list can confirm.
But i have the same silicon revision (PG2.0) in my EVM and I am not
seeing any issues. Can you
point me to the ethernet errata which you are mentioning?
