bnx2: Refine coalescing parameters.
- Set the USE_INT_PARAM bit so the rx-frames-irq and tx-frames-irq will take
effect on 5709.
- Increase the default rx-frames to reduce interrupt count.
- Decrease the default rx-frames-irq and tx-frames-irq to catch more events
during NAPI poll.
All these will reduce interrupts without affecting latency.
