From 2371408c021f961b92fd2c42480cfddc9c6254f0 Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Sun, 29 Jan 2006 00:49:09 +0100 Subject: [PATCH 01/20] r8169: prevent excessive busy-waiting The MII registers read/write function blindly busy waits for an amount of 1000 us (1 ms), then up to 200 ms. These functions are called from irq disabled context. Depending on the clock management, it triggers lost ticks events. Since the value is way above the standard delay required for mii register access, it strangely looks like a bandaid against posted writes.
