From fdb246f526e422b18b48d578085c01ab28ec2c33 Mon Sep 17 00:00:00 2001 From: Michael Chan <mchan@broadcom.com> Date: Mon, 18 Oct 2010 14:30:54 +0000 Subject: bnx2: Increase max rx ring size from 1K to 2K A number of customers are reporting packet loss under certain workloads (e.g. heavy bursts of small packets) with flow control disabled. A larger rx ring helps to prevent these losses. No change in default rx ring size and memory consumption.
