Message-ID: <1250907650-24672-6-git-send-email-mchan@broadcom.com> Date: Fri, 21 Aug 2009 19:20:48 -0700 From: "Michael Chan" <mchan@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org Subject: [PATCH -next 6/8] 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.
