[PATCH] sky2: NAPI poll fix

When sky2 driver gets lots of received packets at once, it can get stuck.
The NAPI poll routine gets called back to keep going, but since no IRQ bits
are set it doesn't make progress.

Increase version, since this is serious enough problem that I want to be
able to tell new from old problems.
